Need Part Number 2005 Escalade Touch Screen Nav Radio

[allwest]

The TNR will go in your 04 Denali with no problem. For the VSS harness it will be interesting to see JP's approach. Unit will be a virgin so no dealer trips. Removing the dash cover is about an hour the first time. GPS antenna is a bolt in and uses existing screw.

Ok, gang - the package arrived from JP Customs yesterday, but they forgot to pack the GPS antenna in the box. A quick call took care of that and the GPS antenna is on it's way (again, overnight shipping - for free). It should be here today.

With the GPS antenna on the way to my door today, I've started in on the installation. What a learning experience! I've torn into the dash of my '01 Silverado before (as I noted previously), but I've never had to remove the top of the dash. There's a lot to remove, but most of it is friction-fit clips and screws. I have pics of most of it, and I'll be posting those as soon as they're edited down for size. There are a few things to note, however:

1: The Yukon Denali (at least in my '04 XL) already has the VSS wire going to the stereo. I suspect this is the case with all Y91 trucks. Not that it matters, but I've got a pic of the harness where that wire would need to go, and there's already a green/white wire at spot "E". It's the same color found on the instrument cluster harness. If anyone reading this is upgrading a Y91 truck to the Nav system, check to see if you have a wire at socket "E" on your harness before going to tap your instrument cluster's harness. It will save you about 15 minutes and cut-up knuckes (damn metal support braket!). BTW - If you're doing an instrument cluster overlay and/or bezel, now would be a *great* time to do it since the dash is already disassembled far enough. It's another 4 screws (7mm heads) and it slides right out.

2: On the Denali, and presumably on all the other Y91 trucks, SCV (Speed Compensated Volume) does NOT rely completely on the VSS signal. I discovered this when the volume was going up and down on me while at the car wash a few days ago. (Funny, I never noticed it before. ) Either the OnStar mic or some other mic is picking up background noise for the stereo.

3: My "virgin" Nav unit does, indeed, work straight out of the box without a visit to the dealer. But it isn't picking up the manufacturer code in order to display "GMC" when booting. Right now, all it shows is "Delphi". I have a pic of this, as well. It really isn't a problem for me, as the Delphi logo isn't that bad to look at.

4: When removing the climate control panel, the 7mm socket I was using slipped between the lower dash facia and the innards down below. D'Oh! There's a small crack where you can drop screws and small tools and it will be just about impossible to get at unless you either disassemble the lower dash or have a magnetic pickup tool (screws are metal, hopefully so are any tools). That took about 10 minutes of fishing with my pickup tool, but I was back on track.

5: The instructions for the JP Customs kit says that a 10mm socket would be required, among other things. This is NOT the case - a 5/16" socket is required instead. I'm assuming that size socket is to disconnect the battery's negative terminal nut - My truck has a 5/16" nut for this, not 10mm. No other screws, nuts, fasteners, etc., are 10mm during the install. In fact, everything else is a 7mm-headed screw or is fastened with clips.

6: If I wasn't waiting on the GPS antenna, I would have completed this in about 2 hours. I started at 0630, and I powered the unit on at about 0815. Add 15 more minutes to reassemble the dash, and we're right at about 2 hours. JP Customs' instructions states 1.5 - 2 hours. That sounds about right to me based on what I've done thus far.

Overall, I'm pleased. I can't wait to get it out on the road.

Stay tuned for pix, too!

This is EXACTLY what happend to me when I was removing the top part of the dash. Unfortunatly I couldn't find the screw even after disassembling the whole middle part of the dash! It was a very good experience, at least I know how to remove all those plastic pieces now but the screw is still down there. Could you tell (with pictures if possible) how you managed to get it out? I don't really hear it rattling but it would be nice to get it back to where it belongs .

I got the TNR for $1025 off ebay, new, never connected. Ordered the GPS antenna from gpspartsdirect.com and should install everything this weekend. One thing I don't think I'll do as stock is the location of the GPS antenna. I'm not very comfortable with it being there in the dash. In other GM cars it is mounted up on the windshield next to the rear-view mirror. That would be a much better place. Especially that I'm planning to put some heat rejection film on the windows and that TOTALLY blocks the GPS signal!

glad it works but still for 1/2 the price, you could have got it off ebay and it WOULD show your logo for your truck...even if it took 35.00 to get it programmed, whats the big deal when you save over a G?

[flyingdutchman]

From the following link http://www.gmtechlink.com/images/iss...e.html#story16

This information appllies to the following 2004-05 vehicles with the UM8 Navigation Radio Sound System:
- Buick Rendezvous and Rainier
- Cadillac Escalade, ESV, and EST
- Chevrolet Avalanche, Tahoe, Suburban, TrailBlazer and EXT
- GMC Yukon, XL, Denali, Envoy, XL and XUV
- HUMMER H2 SUVand SUT

Customers may comment that their navigation radio system does not have complete coverage for their area. This may be due to recent construction, or changes to public access roads or highways.

2005 model vehicles should contain the latest navigation DVD disk release, version 3.0 If not, refer to service bulletin 04-08-126-001.

2004 model vehicles should contain an earlier navigation DVD disk release, such as version 2.0.

TIP: The New Vehicle Warranty does not cover cases in which the customer requests an updated navigation DVD. However, customers can purchase the DVD disk, release version 3.0, under part number 10390370.

An update - The logo is now showing up, which I'll have a pic of "Real Soon Now" (tm). It was kind of funny how I noticed it, too.

I managed to only screw up once during the entire install - I bent the metal clip that secures the drivers A-pillar trim. I went to the dealer to pick up the part ($2 and some change, BTW) and just HAD to show the guys that said, "It can't be done" that it COULD be done. Lo and behold, the GMC logo appeared during my brief presentation to them.

Yeah - I keep getting the, "It's cheaper if you buy the stuff on eBay." from others, as well. I'll be willing to debate this until I breathe my last breath. I still think I got a fair deal with someone reputable, which is far more valueable to me than trying to save a few bucks. After all, I spent about $50k for the truck to begin with, so I don't think that spending a few extra bucks on quality, guaranteed parts is too much to bear. I'm not saying that that you can't find quality parts on eBay, but it's rare to find someone that will/can give the sort of replacement warranty a retailer can offer. Besides, the risk of getting screwed over on eBay is a very real risk that I just refuse to take chances with. So I paid more... If I'm a fool for parting with my money on a product from JP Customs when I could have parted with less through someone on eBay, then I'm a very happy fool.

On another note - I'll have the photos ready in another hour or so (currently 0740 CST), and I'll make sure to post a link as soon as they're ready. To answer another post - I'll have pics of the slot my socket fell down into and where (and how) I used a magnetic pickup tool to retreive it.

[racermd]

Ok - Pics are up: http://home.mn.rr.com/elynch/navinstpics

They're labelled appropriately enough, I hope. A brief narration for you:

I started with NavHUPackage01 and NavHU[Right|Left|Back|Front] to show what came with the kit. You'll probably notice that the GPS antenna is missing. JP Customs didn't package it for some reason (forgot?) and had it shipped separately. I never really did get a good pic of the antenna, so you won't see one from me. I can basically describe it as a circuit board on a metal bracket with a foam-covered wire coming from it. Hardly worth photographing if you ask me, but it could be useful to anyone that hasn't done this before.

The DashStart and DashStartAlt are the "Before" pics of my truck.

The instructions I received stated to remove a fuse from the under-hood box and then disconnect the battery's negative cable. That's not such a bad idea considering that moving the shift lever makes this job a ton easier, if not required. That, among other safety-related reasons, is why I chose to do this. Ordinarily, I'm pretty lax about disconnecting the battery. But there's more than just convenience at stake.

DashApart01, DashApart02, and EmptyHUPocket show the front of the dash pulled apart. You may notice a black metal shaft sticking up from the floor in the right-hand part of the two dash pics. That's a laptop mount I purchased for my Silverado and had to modify to work with the Denali. It's a bolt-in unit that utilizes the front-most bolt on the left-hand rail of the passenger seat. The rest of it (removed from these pics) uses clamps. I'm hoping that the laptop mount can be removed now, but we might still use it for other in-car passenger entertainment such as DVDs, games, MP3s, etc.

Take note of Harness01 and Harness02 - these show the smaller harness from the back of the factory, non-Nav radio. At position "E", there's already a wire (green/white on my truck) that's sending VSS data. No need to tap into the instrument cluster! Position "F" and "G" are empty, BTW, as you can see from the pics. I apologize for the blurry pic of Harness02 - autofocus can be a bitch sometimes.

The only reason to disassemble the top of the dash is to install the GPS antenna, which I never really did get a good picture of. Removing the top of the dash requires the removal of the A-pillar trim. This is only slightly tricky, as it requires that you disconnect the embedded tweeters by using the speaker's wiring harness at about dashboard level. You'll have to twist the trim out of the way to get to it and it can be a bit awkward. Other than that, there's only one metal clip per side attaching it and it pulls straight out. Just be careful reassembling that trim - I bent one of the clips because it didn't go in perfectly straight. Luckily it's an inexpensive fix. My dealer has replacements for about $2 each.

Also be careful of the light sensor bubble. The wires tend to be fragile, so I'm told, and it only requires about a quarter-turn to release it from it's socket in the dash. Admittedly, putting this back proved more difficult than removing it.

After the top of the dash is disassembled, installing the GPS antenna is super-easy. One screw and one wire to route to the radio pocket (a distance of about 4-6 inches and underneath a small air duct) is all it takes. Then the top of the dash can go back on as well as the A-pillar trim.

At this point, I connected up the new NAV unit, reconnected the battery, and replaced the fuse removed from earlier. Since most of the dash is already disassembled, it makes things easier to troubleshoot if there's a problem. See NavHUDelphi, NavHUDvdCheck, NavHUNight, and NavHUNightFlash to see things at this stage. This is also where my unit was displaying the Delphi logo instead of GMC's. I had let it sit for a good 20 minutes, and I still got Delphi's logo. Not until I arrived at the dealer to buy that replacement trim clip did it start showing the GMC logo. I'll try to get a pic of that and edit this post when it's up. That will also serve as my "after" pic.

Everything checked out, so reassembly was in order. That took all of 15 minutes, including the top of the dash and A-pillar trim.

One thing that really helped save a bunch of time is using a "spinner" or "speeder" handle with the 7mm socket to remove and replace the screws in the dash.

When I tried to disassemble the dash before I dug up my spinner handle, I used a traditional ratchet handle to break the screw loose and tried to complete the removal of each screw by hand using the socket on a short extension. Well... the socket slipped at one point and got into the innards of the lower-dash column. Apparently, it was sitting on top of the 6-disc changer and had rolled "backwards" toward the front of the truck. Luckily, I had a magnetic pickup tool (a small, powerful magnet at the end of a stick, essentially) on a swivel-head. I angled it at about 90 degrees and slid it sideways down the slot, magnet towards the driver's side. Once down there, I gave it a spin so I could cover as much area as possible. It took a few tries, but I finally got it out. It did require that I remove the Stabillitrack button panel, however. It's only held with friction fit clips, so all it needed was a tug. Unfortunately, I had to let it dangle there as the wiring harness/clip is a bit tricky and I just didn't have the patience to figure it out right then. See SocketLost01 and SocketLost02 for some basic pics of where the tool went.

There are only 4 screws in this entire procedure that aren't 7mm heads, and they're phillips-headed on the ends of the dashboard top hiding behind the fuse-box covers near the door hinges. Use a stubby phillips screwdriver, if possible, 'cause the door is going to get in the way.

That was it! About 2 hours for install, including the time needed to recover my only 7mm socket from the depths of the dash. I think the next project I tackle will be an aftermarket DVD system with an Aux adapter for the factory system and headrest monitors. I never really was a fan of the overhead system as it can restrict vision from the ISRV mirror out the back of the truck.

Apparently you've not seen the GPS Antenna. I don't think you will be mounting it on your windshield. It works perfect under the dash in the factory location. I have never lost a signal.

Actually I have the antenna right here in my hand. I will take off the metal part (or cut it if I had to . And will get me a longer wire.

I know it would work fine as stock. But the last time I installed this heat rejection film on the windshield it totally blocked the signal off my portable GPS. I had to eventually get me an external antenna and mount it on the windshield. I was surprised but this film REALLY does a good job keeping the car cool (I live in the middle east afterall and it reaches 50C in summer for not less than 3 months!).

I will find me a good black plastic case tho. Even if I had to take the case of the external antenna I got last year. I wouldn't need that anymore anyway.

[Samboosa]

I just read this service bulletin about GPS reception when glass tinting is present (for the 2005 Escalade):

Info - Global Position Sensor (GPS) Performance Degradation #00-08-46-003B - (Feb 9, 2005)

Navigation and OnStar® systems require a GPS antenna in order to function properly. This antenna may be located inside the vehicle. If the GPS antenna is located inside the vehicle, performance of the system may be compromised by window tinting film.

If the GPS system performance is in question and the vehicle has window tinting, a quick diagnostic check can be made by temporarily moving the GPS antenna to an external vehicle surface, such as the decklid or roof. If the GPS function of the navigation or OnStar® system operates normally with the antenna relocated , the repair would not be considered a warranty repair. The subsequent repair procedure or GPS placement would be up to the customer.

Some vehicles have the GPS antenna located on the rear window shelf. Objects placed on the rear window shelf, such as tissue boxes, books, dolls, etc., also have the potential to interfere with GPS performance.

You can get any GM navigation unit and it will work with any of their trucks right.. I saw one on ebay that came out of a yukon. This will work with the Escalade right..

You'll need to check to see if the vehicle it came from has a "Lux" amp. Somewhere inside the glovebox will be a sticker that has all the 3-letter manufacturer build codes. Your Escalade has a code of "Y91" to designate the "Lux" amp. The Nav unit you're looking at must come from a vehicle with the same code. If not, then it won't work properly, if at all.

I know it's tedious and long, but read this entire thread for additional information on the topic. Most of your questions will be answered by many early posts.

im just nervouse because the touch screen i am getting came out of a yukon... i dont want my ext starting um with a gmc logo you know... i want to make sure that the computer of the car will have it light up with the caddy logo... will this work or no..

The image the Nav unit displays at boot is tied the VIN, I think. Once you install it and have the old VIN cleared by the dealer (or anyone else with a Tech 2 tool), it will pull some data from your truck's computer and will display the proper logo.

That's the popular theory, anyway. It *should* work as stated. There's even a guy that took a unit removed from a truck and put it in a Pontiac - a Grand Prix IIRC... The guy has a screenshot of the unit displaying the Pontiac logo. And as far as anyone knows, there hasn't been any of these particular units (touch-screen nor joystick) in a Pontiac before.

[Samboosa]

I installed mine last weekend and it's working beautifully!

It is the 7351 (hope I got that right!) number and it displays the Cadillac Logo when it boots.

Amazing! I just realised that the Auto-Volume wasn't actually working with the old CD/Cassette unit! Only now with the touchscreen it started working!
