Hi I'm new ro the forums. I have a stock Bose radio in my 05 sts an I wanna change it to a stock 05-06 sts nav. I was woundering if anyone has attempted this. The dealer said they wouldn't do it cause it's to much work.. I already have the nav and the nav disk I'm waiting on the nav antenna to get here. A local radio ship said they can install it for $100 which ain't bad I think.. I know once it's installed I got to take it to the dealer to to get it unlock with the tech 2 tool.. I was just woundering if any of yall had any info on whatelse would i need.. The only think on here I found close to this was the swap on the cts's an older sts's.. If anyone has any info it would be very helpfull.


Thanks
Jose

I tried it on my last 05 STS. No luck. The GPS never moved. No voice recognition. Basically the BUS does not support all the functionality. So unless something has changed, it looks cool, but there will be no CPS functionality.

I opted to trade my old STS for another 05 STS with the nav and XM installed.

Anyone else can chime in but that has neen my hands on experience.

Thanks.. Just woundering did u have a navigation antenna.. Cause the dealer said that I would have to upgrade to a "shark fin" antenna which is a navigaton antenna..how did everything else work like any other troubles?

As I understand it, the problems include a different wiring harness and the interface between 2 different network bus's. The shop you're talking to must not have ever done it or they wouldn't be quoting $100.

Your Nav Head unit will grow in value as more out-of-warranty cars have issues. All the Denso units are serviced by them - depot style. Most aftermarket shops are not yet able to fix them.

IMHO, find the STS you want and work a trade. You'll be a lot of time ahead. If your time is free... Have Fun!

So basically I shouldn't even try it.. I'm not really worried if the nav doesn't work I never travel out of town..

Welll, the Nav screen does look cool... Much better than the base level dash. The tunes are great but you probably don't have all the speakers, etc. You may have to put in the armrest input jacks to get line level input functionality. XM requires a module in the trunk. All your memory settings (seats, remote start, etc.) are stored in your current head-end so if you change it out you'll really want full functionality of the Nav head-end.

If overcoming technical complications sounds like fun, more power to you. It has been done by at least one member of this forum.

On the other hand, if you can do without a lot of those tricks, maybe you should consider an aftermarket Nav/Head-end in that slot. Regardless, I don't work on my late model-daily driver cars much anymore. I have a TR6 hobby car that I can keep running with rubber bands & tinfoil. (Points! What are points?)

I'd just advise you to pick your battles. I'm not getting any smarter, but I have learned a thing or two!:o

Ok I'm sure they can hook up the DVD spekers to play on the stock spekers that wouldn't be a problem.. It might not sound as clean as the stock DVD suround Sound but. I don't wanna get an aftermarket nav cause I know I'll loose being able to program sutff to it like seat positions stuff like that.. At least with the stock nav I can well at least I think I can.. But thanks fo ur input if anyone else has something to say please feel free...

You should be able to find the thread where a member described his project. I think it was about 2 years ago. (My wife thinks I'm addicted to this site because I've read almost every thread.) The search function on this forum is a bit cumbersome but with some persistence, there's a wealth of information here.

Serendipity is a wonderful word. In finding the answer to your question, you can learn a lot.

Have Fun!

IMHO- find yourself a good aftermarket unit, you will be much happier.. The stock unit doesn't work when you are moving (unless you add an expensive , unsupported, aftermarket wiring harness) , MP3 limited to cd's vs DVD, the nav disks are expensive, and the unit itself is marginal at best as a GPS unit.. It won't look as clean as a stock unit but will give you better overall perfromance..

Your dealer has no clue.... The GPS antenna is in the dash not in the fin antenna. The swap can be done but its not worth the cost and time. If you dont have the 15 speaker bose system then you are definately not getting it done since the entire bose amplified would need to be replaced as well.

I do know that some Bose systems ('98 STS comes to mind) have speaker amplifiers external to the head-end unit. I have no idea about our cars but the Bose system may not even be close to what's needed.

I trust Tomm's opinion.

Hey guys just wanted to update yall.. I got my nav installed today everything works fine an I payed 80 bucks instead of 100 they took like 2 to 3 hours to install it.. Then I took it to the dealer to get it unlocked with the tech 2 tool an they charged me like 110 cause they upgraded something I forgot already but the bottom line is that it can be done!!! And I got it all for under 900 buck... The next thing is a lockpick but I'm not in a rush to get that.... So if yall have any questions feel free to ask I maybe able to help..

You are not missing much because the STS nav leaves alot to be desired imho.

I've read a lot up on this. It's not an easy thing to do and I was quoted roughly $4000 for the dealer to add it in. Your best bet is to go to an aftermarket unit but then you lose all the "options" the factory one gives you.

I figured it wasn't worth the time or money even though it's something I really wanted to add. Next Caddillac I will make sure the model includes everything I want so I don't end up short in the end.

Hi all, has anyone found the old thread on the Bose stock single disk conversion to the "YQ4" 6 disc/DVD/Nav? I almost bought the unit but sure would like to know if it will work. Tried an aftermarket head-in but no one has a harness adaptor for my 05 STS.... Also, I can't get an answer if the 6 disk unit has the XM integrated or a separate tuner. I found all kinds of GM part numbers.
468100-5112 6 disc cd
468100-5113 6 disc nav
Sure could use some help!

Was this a chain shop, or local? I'd considered doing this on mine but was under the impression it "couldn't be done" but sounds like that's not the case if you got it for <$100.

Any suggestions on parts list (what would I need to supply).

To be clear, your car HAD the Bose 8-speaker with 6 disc in-dash CD, and you swapped for the stock Caddy NAV unit, seat memory still works, etc?

Well as soon as i receive the Nav unit i'm going to try it. I don't have seat memory as an option but what the heck! The Nav antenna under the dash is going to be fun if the yard doesn't have it. ($173 new) Apparently, the XM tuner is in the trunk under the rear window?? Now the poor yard has to try and find it....or a new tuner for about $100.00 so if anyone has more info, i'd love to hear it. Especially any problems or non functional options once it has been done.

Thanks,

Yea I had the Bose 6 disk.. I got a homeboy that works for that shop that's why they did it for 80 bucks but at first they said 100 which still isn't that bad.. If u do do it ur gona need an navigation antenna which I got on eBay for like 30 bucks.. Even the guy at the dealer was suprised that it was working so good he said he never seen it done and everything work on it as good as it is.. He did hook me up with the softwear stuff he said that it would cost Iike 6 or 700 but I was just being cool with him and he unlocked it an did the softwear update for 125 which is a good deal...
The only thing that don't work is the bluetooth well it does but were I got it installed they said that I would have to install a mic so the other person can hear me but that's the only thing..

What I suggest u do is call or go to ur local dealer and ask them how much would it be to get it unlocked and if it needs to be updated how much would that be.. See if it would fit ur bugget..

If I u got anymore questions feel free to ask..

I too have looked into doing this. I was told and looked for myself that if your STS does not come with nav, you do not have the wiring. I took out my non-nav cd player in my STS, and compared my wiring harness to a picture of a nav wiring harness, and you can see that my non-nav wiring harness is missing a lot of wires.

I cant post links yet but, go to ebay and either search for store called LKQ or search for cadillac sts navigation. Either way get to the store called LKQ. Look at their nav's and regular 6 discs for the STS. If you click the pictures some of them have pics with the wiring harnesses still in them just cut. You will see the differences.

You can acually see on the back of the non nav the where the cut out is/would be for the other harness if it were a nav.

so the question is what are the other wires? Is it possible that if you plug in just the non nav wiring harness into the nav it will work or work missing some functions.

Can you ask your friend or place that installed it what all they had to do?

yea i know what u mean about all the extra wiring.. actually my friend took it to get it installed cause i had to work that day and he didnt pay attention to how they installed it.. hes not an installer his more like a sells man for that shop...anyway if u are thinking about it make sure when u buy the nav system that it has the wiring harness ill make it a little easyer to get it done... i havent had a chanse to look back there ill probably do it this weekend if its not to hot .. ill take some pics so yall can see it too...

one thing i did notice is that when i got the stock radio it had the nav wiring harness on it it wasnt complet i dont know if the stock harness just pluged in the back of the nav system i do know that 3 plugs are the same but ill let yall know for sure when i take a look myself..

polarbear05
08-05-09, 09:48 PM
Hey guys i just took a look at it and just the two plugs that ur car comes with are connected to the nav system... i dont know what the other plugs that it has are for but everything works on it..

stock 6 disk bose has 2 plugs..
stock nav bose has 4 plugs..
(plugs were the wiring harness connects to the back of the radio)

I thought they had more plugs but they dont sorry if i got anyone confused i think i said it had 3 plugs that were the same or something like that but i was wrong...

it looks like it just plugged up to the stock wiring harness(2 plugs) thats what it looks like.. basically like a plug an play type but that sounds too easy u know what i mean

my car is an 05
the nav was from an 05-06
so i dont know if different years have different connections or if there the same...

Im still wondering what them other 2 plugs are for??but they must not be that important cause everything is working fine...

Possible to post some before/after pictures ? I'd greatly appreciate it !! Right now my car does NOT have the nav. and the dash looks very bland/plain. These cars were designed so the nav. would be a part of the dash. Just the regualer radio with no nav. looks very "goofy' lol.
Thanks for the (already) posted info ! I'm just wondering if it's worth pursuing or not ?

If you could, please ask your friend or the shop what they had to do to make this work. I have read alot of posts on here with people trying to do this, so I am sure that alot of people will find this information very usefull. I was about to order a replacement regular radio and try to do the CTS mod to take the 6 disc out to make a custom aftermarket nav install and still keep the stock radio for the settings. But I would much rather just install a caddy nav than go through all that trouble, as I think it will be harder than doing the CTS mod. If you could find out though that would be great, before I spend the money on the nav.:bouncy:

Thanks

08-08-09, 04:16 PM
well I talked to my friend and he said that the stock wiring harness just pluged right in to the back of the nav.. It just took the installer a while to check the wiring on it.. So it just a plug an play type and I could of done it my self i would of known that.. And after it's on u just have to take it to the dealer to get it unlocked and that's basically it..

Did all functions work? seat memory,fob recognition,greeting,ect?

Polarbear05 - you are my hero!...:worship: LOL...I too would LOVE to see the pics. If the Stock Nav works in an STS that had the non nav 6 disc Bose, this is, without a doubt, the BEST way to go.

He sent me two pics. One of the NAV front with it on and working, and one from the top of the nav with it pulled half out looking down showing the harnesses. All you can see is that only the stock non nav harnesses are hooked up and there is a single wire running into the pins on one of the other plugs for the other harnesses that are not hooked up (GPS antenna?). I will post links to them later today when I get to my computer. I am on my iPhone right now.

Here you go. These are the only two he sent me. I am still undecided if I am willing to chance spending the money on a stock nav without more confidence this will work. I don't want to be stuck selling one on ebay because it wont work.

I did find a stock STS radio in very good condition on an ebay auction, and I won it for $32. I got it now and I am going to try to take it apart and modify it to take an aftermarket nav like has beed done with the CTS radios.

snum1fan,

Thanks for posting the pics. That single wire comming out of one of the connectors is interesting. Perhaps the pin out for the non nav and nav head units could tell us what we need to know. I am though, very curious to the modiciation you are going to do with the non nav STS radio. I too would like to do something like that as well and in looking at the radio structure, it seems the ideal add would be to modify the middle pocket thereby eliminating the articulating door. While measuring it up, I have done some research and come accorss with some small (1 DIN) units have potential to package (with modifications) in which the screen projects and flips in and out of the unit. The trick is not only to find one that packages but with one that the screen does not cover the radio controls. Then ofcourse, trying to integrate it (electronically) with the existing radio. I have a few ideas there too but not sure if they are feasible....

Really curious on the mod you were thinking.

It'd be nice if the person whom ever hooked up polarbears OEM nav explain what and how he did it. As buying the OEM nav would be ideal (if it would work).

I wasn't going to just take out the pocket. Look at the cts FAQ for modify center stack to take aftermarket nav. I am going to remove the 6 disc and the pocket creating room for a double din. I will then have a custom fiberglass mount made to fit the after market double din nav in. I have had one made before for a car that I could not find a mouning kit for theybusually run around $150


and Thanks polarbear soon as I get them I will post them

caddimike
08-24-09, 02:47 PM
Hmmm, interesting. I'll take a look at the cts FAQ...I never thought of having a custom mount made...$150 aint too bad....

I am still going to attempt to get the pin out for both radios (that may help explain how polarbears was hooked up), if I am successfull, I will share with everyone (if interested)

Polarbear - That would be outstanding...thanks!!

Hey snum1fan I found this double din kit when I was lookin to get the nav if he stock one didn't work I'll had to go with an aftermarket indash.. Well I found the kit on eBay i think it was less then 40 bucks.. Here's the item# 390061895360.. it might be better then spending the 150..

"This is the stock 6 disk with the nav wiring harness.."
This is what he said in the email.

I replied back and asked him what he meant by with the nav wiring harness, and where those harnesses came from, I dont see them hooked up, and non nav cars do not have them. My guess is that they came in the back of the nav and the wires were just cut.

snum1fan
08-24-09, 06:15 PM
Here is our little discussion after he sent the pictures.

I said---

Thank You SOOOO much!!!

Where did the nav wiring harness come from? Was it in the nav when you got it, just cut off wires? Is it in your car?

So, you just had a stock radio with the two hrnesses coming from your car. They took the radio out and hooked the two harnesses that were in your car for the radio to the nav? So right now the only thing that is hooked up to your nav is the two harnesses that were originally hooked up to the stock 6 disc radio, and the other wire for the GPS antenna? Right?

He replied---

Yea that one came with the nay unit.. An ur right.. Like I said on the forums I wasn't there when it got installed my friend was an he said that it took the installer a while cause he was checking the wires to see if they were the same.. One thing I did notice on the sound was that it sounds a little better like the bass hits a little more I guess the nav unit has more power going out to the speakers or something .. And when I play a DVD it uses all the speakers so it sounds nice too.. I'm sure not as good as the 5.1 suround sound or what ever it is..

Here are the pinouts from alldata that I found. Some are labled nav/tv, some are labled radio, but you can see from reading them what they are for.

On another subject could you please get the exploded view of the 08-09 sts front bumper assy. I am putting a 08-09 bumper cover, and grill on my 05, and I would like to see if anything is different on the exploded view than on mine.

snum1fan, polarbear,

Picture says a thousand words...

OUTSTANDING!

Makes you wonder why all the "experts" said it couldn't be done...

Couple of questions:

If you label each connection of the nav radio as 1,2,3,4

You can see in Polarbears car connector 1 and 2 are not hooked up at all...pretty straight forward.

If I'm interpreting the picture right, connector 4 looks as though it is a direct replacement as in the back of the non nav radio...

Connector 3 has me puzzeled a little. Perhaps that is the harness was modified by the shop polarbear took it to to get it installed?? I'm guessing yes.

Comments?

Once again, thanks for all the work you guys have done . . . I very much appreciate you guys sharing this info

Thanks for putting the pin out info but when I click the links, it doesnt connect me to the pin out data...in fact each link is a different diagram from anything but electrical...strange

In snum1fan's defense, the links did work earlier. Your right, they don't work any longer.

I have no idea what happened to the links. I couldn't figure out how to put them in the post or upload them to photobucket. I will use the snipping tool in win 7(and vista) and try to put them in the post.

snum1fan
08-25-09, 01:34 AM
Im going to check Tom. But I'm pretty sure that my connector number 3 looks just like that one. I know that there are barely any wires in it. Tom I will loom and post pics of the stock non nav harnesses.

snum1fan, polarbear

Okay, I'm a little confused...again...sorry.

According to the picutre both connectors of the non nav radio (6 disc) were well populated. So, if I understand correctly, polarbear, did you then just plug in the cut harnesses from the nav radio into the back of the non nav radio, held the other 2 nav harness, and then snapped a photo???

I just find it hard to believe that no splicing or mods are needed and that both non nav harness plugs right in to the nav and it works! If that was the case why has it been so well documented that the swap just doesnt work....until now??!? Oh well.

I'm sorry for the questions, I just want to understand how the hell this got done and it seems you guys have this thing almost figured out ... please don't read this as being mad/frustrated....this is exciting!

snum1fan, although you have an idea, (like you indicated) it will be interesting to see what you find when you pull your non nav radio...

Thanks again for all your work

snum1fan
08-25-09, 01:05 PM
I am trying to find out just like you if it works for sure. I have not saw anywhere where somebody tried this. The only posts I have saw are where people ask if it can be done and are told that the wiring are not there. If you look in the CTS forum, it has been done there many times, besides an antenna and a wire needing to be spliced for the door chimes to work, it is completely plug and play.

If you look at his picture of him holding the harness. you can tell that the orange one has no wires coming from it, and the black one looks like it has barely any.

I dont know. Like I said, I will pull my radio today and take a couple pics of the harnesses, and post them.

caddimike
08-25-09, 02:27 PM
Awesome, hopefully it will help answer all the questions.

If I'm not mistaken, there are probably at least 6 to 8 pins assigned for the input (for MP3) and audio/video connections located inside the center council found in a a vehicle with a stock nav from the factory.

I'm guessing Polarbear's hook up was minus the Input and A/V connections. If all checks out, I may try to wire them up. The FM modulator for an MP3 just doesn't cut it for me. Although I probably wouldn't need the A/V line out connecitons, it wouldn't hurt to try and wire them up while installing it if its not too much trouble. . . I'm thinking pigtail instead of cutting the storage bin.

On second thought, aside from the additional 7 speakers the nav unit is equip to power (perhaps another 14 pins?!?)...I can't think of any other option that would need a vehicle harness connection to the radio...

Yeah, lets see what your hook up looks like and I think all the conclusions will be drawn...hopefully. Once again, appreciate (everybody's) your work here!

08-25-09, 05:37 PM
I also did a lot of research on this an a lot of people were saying that it was impossible cause I didn't have all the wiring needed for the nav unit.. But
I only found one guy that did it but he said that his nav never moved I don't know why or if that nav unit wasn't working right.. He posted on here I think he's on te second page or something.. I don't have the video out put or that other thing.. But like I said everything works fine I can even pair my iPhone thru bluetooth but I can't hear anything don't know why nut I can care less about that I'm just happy it worked out as good as it did..

If anyones has a question feel free to ask.. I'll do my best to help u out..

Ok I am going to the dealer to get my other radio unlocked, or attempted to be unlocked tomorrow. So I will take the pics and post them then.

What I do have though is the wiring diagrams. This time I used the snipping tool and then uploaded them to photobucket.

http://i687.photobucket.com/albums/vv235/snum1fan/snip6.jpg

I know there are 6 diagrams here. These are all of the diagrams that alldata provides for the radio/nav.



Oh yea, and about the fm modulator. I got so sick of mine that I went out and bought an ipac until I figure this nav out. I found one for a sts, but you gotta make sure you get the right one, because I saw a few that said they would fit, but if you looked really close you could see that the plugs were a little different.

The one I got works great, 100% plug and play, no power wire, nothing. You just hook the two harnesses into the radio, and then there are two that plug into the car harnesses, then a plug goes into the ipac box, and you have dual aux inputs. You could have two ipods hooked up if you wanted. It sounds 1000% better than fm modulator. I cant tell the difference between my ipod now and a cd.


Thay are around $149 at alot of stores online. I found one for $80 at a couple of them though.

snum1fan,

Good stuff, thank you! Boy was I off on the pin outs...lol...
An Ipac eh? I think I still have one of those. One of these days if the nav thing doesn't work out, I may go that route.

Good Luck tomorrow, we'll all be waiting for the pics and results.

Thank you!!!

As you suspected, no different than polarbears hook up. So J2 utilizes pins 1,2,5,9,10. Thats it, right? The pics were just a tad blurry but good enough!!! Just wanted to verify.

Also, now I see what you meant by an Ipac. I was thinking an Ipaq. You know the HP personal organizers before they started integrating them as phones...LOL....I was looking at the Ipaq I had and wondering, how the hell did he do that???

Awesome work!

Just curious, is there a trick to popping off the wood IP panel without damaging it?

snum1fan
08-26-09, 10:40 PM
To take the wood off you just start at the top and pop the top clips and then work your way down to the bottom being carefull at the bottom not to crack it because it is really thin there. I have took mine off over ten times and it still goes back on nice and tight.

Sorry about the blurry pics. I don't know if it was my lens fogging up or what.

i was comparing my stock harness to the pictures of the stock harness that snum1fan posted and noticed that on my black connector i only have the pink wire. if i was to put in the aPac-sts would it matter that i didnt have them.

my 05 sts doesnt have xm or anything so im guessing thats what the missing wires are. im getting a little frustrated with the whole process of trying to hook my ipod up to this thing. i need some help.

11-28-10, 05:56 PM
So did you buy a uPAC-STS, install it and find it didn't work?

If not, did you find a uPAC-STS vendor and ask them if it would work with a non-Nav STS? If they say yes, pay for it with a credit card and you are protected in case it doesn't work. You can just ship it back and file a dispute if the vendor won't reverse the charge.

Come on... You own a Cadillac! Show some initiative!

Ok so with this ipac thing u can hook it up to the nav an have the video/audio aux inputs with out having the stock video/audio aux connection the one that goes to the back of the nav.. Like do u just connect it where the stock connection goes or what?

11-30-10, 05:13 PM
i bought an 2005 sts with a stock bose system. i looked into swapping out with an sts navi system i found on ebay, well to make a long story short, it was easier to add a single din head unit(flip out monitor) into the space between the radio and the stock cd changer. making this work all depends on going to a reputable installer to save the onstar on the stock head unit. if you want pics i put an ad on the classified section with my number. ill text you the pics.

dchun81
11-30-10, 09:46 PM
when i bought the car, there was a void space with a flip to open cover(perfect size for a single din). the metal bracket in the back was cut open so the head unit was sit flush. ill post up pics soon.

LAC_STS
12-01-10, 12:54 AM
Yea I have that same radio with the flip up storage compartment. I took mine apart and was going to put a double din in there with a custom fiberglass faceplate made.

But then I got the STS NAV instead.


Modding the stock CD player to fit either a single or double din unit is NOT easier than the OEM NAV upgrade. With the OEM NAV upgrade you just unplug your radio and plug the NAV in. Then run 1 wire to the trunk. Oh yea and have the dealer unlock it.

Alot easier than modding the stock CD player. Besides the 1 wire its plug and play.

If you don't keep a stock head-end wired in, you lose the ability to change car settings. A dealer once told me that an owner installed an aftermarket stereo but wired the old radio into the car in the trunk!

okay i have read through this whole thread and nobody has mentioned this one wire running to the trunk but you. could you please inform us/me on this one wire and where it need to go exactly and what it is for?

also, could somebody explain this IPAC thing a little better please? i want to ad my Zune to my radio, but want to get the best bang for my buck and if the FM modulator isnt cutting it, then i need to look into this IPAC

thanks in advance all

Echas: Theyre talking about adding a NAV to the OEM radio. The OEM radio would still be hooked up. the NAV would just be hooked up to the speaker wires.

You can look in the 1st gen CTS forum and see what were talking about. Theyve done it many times.


txbest: Read the other threads on the OEM NAV install. theres another one that is titled something like "NAV confirmed thanks polarbear" Its all discussed there. Basically you have to run a wire from the brownish red connector on the NAV (you wont have this connector. You either have to buy one or buy a lockpick) to the rear parking assist module in the trunk.

The NAV's GPS needs the VSS wire as it relies on VSS more alot for tracking. The NAVs GPS screen will freeze facing east if you dont have it.


I forget which one I had before but I think its the Ipac. You have the have XM to be able to use most of those units (ipac, upac, etc). You just plug it up and it works. I dunno what else to explain.

Yes, very true but what a pain the ass. Happens on all GM's at one point in time, either us for the seat/vehicle functions or cheaper GM's for their head unit lock out, when people don't change the whole stereo they need to keep the OE deck in place to have it function.

EChas3
12-02-10, 11:20 AM
Is the wire you're referring to the XM radio antenna wire? It would then go to the roof antenna.

The AM/FM antenna connector resembles older cars only smaller and the antenna is embedded in the rear window. The GPS antenna is under the front dash. I think the Onstar antenna is in the mirror.

I'm not familiar with IPAC but have the uPAC-STS installed. It's from Pacific Accessories Corporation and utilizes the XM interface to provide support for various add-in's. I have the iPod & HD Radio modules. They are controlled using the OEM radio tuning knob. The iPod interface provides a powered connection on a standard plug (audio-only) and the screen is just for control. An additional antenna is required for the HD Radio module.

Assuming my installation is a different product, I'd also be interested in details about the IPAC feature/functions.

12-07-10, 12:27 PM
If you werent gonna go with the OEM NAV I would have went with a double din 7" aftermarket NAV.

I have an OEM STS radio gutted and ready for one. All I have to do is have the fiberglass face/adapter made ($100).

Like in the 1st gen CTS forums the double din looks nicer than a flip up. Your covering your radio/settings controls anyways.

dchun81
12-10-10, 09:50 PM

LAC_STS
12-11-10, 10:31 AM
but will you still have onstar and driver settings active like i do?

Yea all you would have done is removed the cd/changer tray. The whole radio only uses the little board in the top.

If you take the radio apart and disconnect the ribbon cable going to the cd/changer in the bottom an take the cd part out you have a nice spot for a DD.

I tested the radio and everything works fine with the cd part removed.

I got a quote at a high end local mobile A/V shop to make a custom fiberglass face/adapter for a DD and it was gonna be $100-150.

my question for you though, how did you wire up the radio?
