: replacing factory radio with After market

Hi there, I am a new Cadillac Owner. Mine is a 1997 DeVille 4door Sedan I fell in love as soon as I sat in it and drove it. So Here is my question. I know NOTHING about car stereo systems from RADIO to SPEAKERS!! All I do know right now is that the factory radio that is in there is
1) not working
2) according to the Dealer not the right one for my car because the VIN doesn't match.

So the dealer suggested getting an After market system to put in there. NOW I don't need a whole DJ system to blow the windows out of my neighbors house as I drive by. I just want something simple.

So here is what I do know. I am going to need an Aftermarket installation kit.
I found this one. Is it the right style (and YES I only want the single DIN)

(I have included with it the wiring Harness and an Antenna adapter.)

Second. I am understanding that my car might have 6 speakers instead of 4 is this right? Is there an output amount that I should be looking for when choosing as stereo or is there a inexpensive Stereo that someone can suggest.

Well I know you'll need a wire harness to integrate your aftermarket deck securely without splicing and making a mess. You'll need one of these:

I'm not sure how to tell besides counting and looking how many speakers you got.

Also may I recommend if your upgrading and have music playing off a iPod or want extras like navigation like a double din has. I'd suggest a single din flipout.

VIN doesn't match because its not the original HU,
They have to unlock it, in order for them to do so they need proof of purchase for it, since it has another's car VIN programmed into it. These aren't your typical stereo deck. Your cars theft lock system is tied into it, it mainly acts as just a remote for the radio integration module(RIM) behind the back seat, assuming it is the BOSE system

Missy we still need to find out if you have the Bose Factory audio system
i know you have all the thing that you plan on getting
and you didn't want to spend the amount of money that you would need to to put a aftermarket head unit in your car if you had the bose
and in that case if you do have the bose probably the best thing you could do is repalce it with a Used head unit
but if you are looking for CD player in dash i don't think they had a IN Dash CD head unit in 97 i think it was seprate cd changer


if you don't have bose then adding a Aftermarket Head unit will be much cheaper and easier then trying to add one to a bose system

Ok , Thumper has told me how to check for the Type of System I have. I am not looking for anything fancy. Actually what is in there is fine if it would just work :-( But I will check things out more on Wednesday since I am off work. I will get back to you guys with the info.

Thank you all for your help!

SO the Dealer could have unlocked it for Me??? Oh that SOB ...I knew I didn't like him when he started off telling me I should just sell the car for what I could and get something less expensive to repair...GRRRR I hate when people just don't want to do their jobs....*sigh* NOW What do I need to know about this ...I am also looking to get a remote keyless entry. Thumper said it might have had one they just didn't turn in. I see on the Dash board when I turn the key it does have a SECURITY that lights up. ..There is just so much to learn and do with this car....*sigh* I wish I had someone to just take care of it for me :-(

Missy
the Keyless Entry remote can be found on ebay can probably pick one up for 20-30 buck used
just have to find out the right part number
if you call the dealer and contact there parts department with your vin number of your vehcile
they can tell you the proper part number for your remote
once you get one you will need to go to the dealer to have them program it with the same tool that they would use to unlock the radio

the only thing is with the radio
we need to find out if it is the Original radio and for some reason it just locked up and in that case it could be bad

or we need to find out if the radio they replaced it with is the proper radio for your car
they could have put in a radio that will not work with your car and that may have been why the delaer was saying its not the right one for your car

but yes just because its not the original radio does not mean it can b right
people replace parts with used partes and devices all the time

Yes, the current HU is a stock one (Denso),but not the original stock one, then yes it needs to be unlocked at the dealer and can only be done with proof of purchase.

I have never had to show proof of purchase to have the radio unlock in te Cadillac or te HhR
The only time a dealer ever even asked me for proof of anything was when I needed them to cut a key from a code for me

03-28-12, 09:18 PM
Ok so I went out to my car and the speaker ,in the front above the dash, is Missing. SO no info on there about the system. I know you told me to look on the wheel cover or something but there was just a bunch of rows of numbers. I have NO CLUE what they all are. So I have NO Way of knowing if it is a BOSE System or not :-(I don't know what they did with the sound system. the door speakers look in tack didn't check the back. will do that tomorrow.

Proof of purchase? I have that I purchased the car. What else would I need since I didn't purchase the radio that is in it?

ThumperPup
03-28-12, 10:05 PM
Missy the row of numbers you see or rows of numbers they are pro codes
hmm not sure what the pro code for Bose is

anyone here know what the proper pro code for Bose is ?

Missy if you call up a Cadillac dealer ask for there parts department im sure the parts counter guy or gal would be happy to spend a few moments to check your car if you can give them you Vehicle Identification Vin Number
on the dash board right side corner near the window or the number its on your title also
and they will be able to look up if you have bose or not

ESCALADE200224
03-28-12, 10:50 PM
Yes, the vin will tell you if it came with Bose, Bose premium, or non Bose at least when it came from the factory. I doubt some1 would replace the amp with the wrong amp. If you don't have a speaker in the middle then that's a good clue you either have a standard Bose system or non Bose.

mlc3409
03-28-12, 10:55 PM
It looks like there was a speaker there and it was just taken out. the cover was partially off and the dash is lose like someone was taking the system out. Anyway. There is ONE speaker in the center of the dash. I did make a copy of the Tag in the trunk. I have a website that was giving me the codes and what they are for and so far from what I can see I do not have any codes that are for BOSE System.

The ones that I have found related to the radio is

U57, U1L, UW6

I have to take a better picture of the label as part of it was cut off. I will check more tomorrow but at this point I am saying I DO NOT have a BOSE system

N*Caddy
03-29-12, 08:47 AM
YES that is affirmative, you do not have BOSE, that is the base sound syste that came originally with your car.
And since nobody noticed your car is a '97 it means IT HAS NO THEFTLOCK so no matter what '96-'97 U1L/UW6 HU you install in the car SHOULD WORK with no problem (no VIN clear needed). Also your car should only have 6 speakers, 2 6x9 in the rear shelf and 1 round 4.25' and one small tweeter in each of the front doors. The yo-yo from the dealership either is full of *#*$@ or is full of $@#@%.
Can you describe what you understand by "stereo not working"?
Does it powers but no sound? Is your trunk release working? How is the radio fuse?
Do you see the clock display?
Is the clock display accurate or always 12:00?
Are the HU backlights working?
Any IRC codes?

Since is a Deville we are talking about, taking the HU out and inspecting the harness behind is a matter of 30 seconds. Just pry the bezel around the HU. That will reveal on each side of the HU 2 steel tabs. Press the tabs simultaneously towards the HU to release. Then pull the HU out and have a look at the 32 pin blue connector in the back, is it connected? Any signs of tampering with (as in evidence of a previous aftermarket install)?

Hey there is the man N-Caddy
thanks for helping MIssy out
i think she said that it does ask for a code of some sort
and yes the yoyo at the dealership should have known this
wow you learn something new every day i had no idea that 96-97 did not have theft lock wow

mlc3409
03-29-12, 08:18 PM
It does not have any power. All it says is LOCK on the front. The front of the HU says theft lock on it. I will take it apart tomorrow to check out the wiring. Thank you for the info. The dealer told me that the HU that was in my car isn't the one for my car because the VINs don't match. Didn't tell me anything except to replace it with after market one.

----------

Oh and yes the trunk release and gas latch release is working.

03-29-12, 09:22 PM
Are you sure the Deville is a '97 not a '98?
If it has the LOCK text on the screen (and just by that I could have told you is a base sound system as the BOSE display "Theftlock Activated") then we have 2 options:
1. The car is indeed a '97 but somebody installed a '98+ HU
2. The car is '98 and somebody replaced the HU for some reason.
Regardless of the above 2 the HU is not original to the car.

There is a 3-rd option somebody replaced the PCM and the IPC in an attempt to lower the mileage the vehicle in which case the HU may be original to the car (but the car is NOT a '97 is a '98) and now the HU indeed does see a different VIN (not your original VIN).

Regardless, the only difference between the '96-'97 cars and '98+ is the HU. Even the '96 and '97 cars can support a HU with the theftlock feature just that the '96-'97 HU never had this feature.

How is theftlock working:
1. Any car '96 and newer support a command on the data line GET VIN. Any module can request the PCM or the IPC for the VIN (including a TechII tool).
2. The theftlock HU at startup first request on the data line this infomation (sends GET VIN).
3. The PCM (in your car) reply with the VIN.
4. If the VIN is not received the HU will NOT start at all (will just display the clock as 12:00 when you press the clock buttons). Just so you know the HU is not managing the clock, it is just a display the clock is stored in the PZM (in the OP’s car). This is the case when the HU is bench tested (it won't start on a bench test).
5. If the VIN is received then:
a) If the HU has no VIN stored in its memory will store this VIN (thus locking on it) and continue with the starting sequence. This happens first time the HU is installed in the car (at the factory).
b) If the HU has a VIN stored then it compares the received VIN with the stored VIN. If is a match will start,
c) If the HU stored VIN is no matching the one received will post a “LOCK” message and cancel the start sequence. It will display the correct clock, it will do the chimes just you can’t start it.

When you swap the HU between vehicles basically you are in the 5.c), the VIN stored is not the same as the one received from the data line. There is an instruction that can be sent (on the data line) to the HU to clear the VIN in memory and reboot. As a result it will go into situation 5.b). This instruction is ONLY implemented in a TechII tool.
There is also an instruction that can be sent to the HU to read the stored VIN. This is how you can track back to the VIN of the vehicle the HU was installed previously (so that’s how you track back).
A dealer is obligated to ask you for a legal proof of sale of the HU where the donor vehicle is specified. Before clearing the VIN from HU the technician should actually read it first and check is matching the one in your paperwork. So the donor vehicle VIN is not required for the actual clear procedure, just for legal matters. No papers, no VIN clear, but there is always the friend of a friend who has a independent garage and a TechII.
What I would do if I were the OP, I would go to the dealer and ask to provide you with an electronic readout of the HU VIN and the vehicle VIN. Check which one is matching the one on the plate (lower left corner of the windshield). If the VIN on the HU is not a match then the HU is not original. If the VIN on the vehicle is not a match then suspect the mileage was tampered with.

:confused:OK WOW....Talk about my head spinning. You are a WEALTH of information. Unfortunatly being Dyslexic is making it hard to read all that you typed. lol

Ok I think I led you astray. The Only DIGITAL read out is LOCK
The "theftlock" is PRINTED on the bottom left corner of the Digital screen.
The radio will not turn on. does not show a clock. basically just does NOTHING but have to word LOCK on the screen. I think I have a picture I can post. If it will let me ......Ok this gives you all a better Idea of what is going on I hope. MAN I can be confusing at times. I'm sorry. I truly am NOT A DITZ!!! I SWEAR!!!

and this is part of the tag from the back wheel. That shows the VIN You all would know better then me about if it is a 97 or 98 89065 WOW I should have done this when I posted this thread..would have saved you guys alot of typing

03-29-12, 10:52 PM
well that radio is for sure from a 98+ also since it says Theft lock on it
the other thing is you have a Mysterious red switch on next to the Head unit
makes me thing some little kid or ghetto thug want to be had some cool system or
thought they where hip by adding stuff
makes me think there was probably a lot of audio stuff added and then they yanked it out before selling the car and could not find the Original Radio so they just took the first used one cheap they could find that would fit in not worrying if it was the right one to put in there

ESCALADE200224
03-29-12, 11:03 PM
Yea the red switch gives it away saying "I don't belong here!". My guess is you need to have it taken out and put in some aftermarket or have it unlocked. That radio again says I don't belong here!

03-29-12, 11:19 PM
well it is for sure coming out. Thank you ALL For your help in this matter. Didn't expect it to get this long. So I am ordering my Dash Kit, Wiring harness and Antenna Adapter and my radio so I should have them in a few days and then I will have a RADIO!!

ONE THING COMPLETE!!! Only Three more to go :-( This was the cheaper of them all LOL

To unlock your existing HU you pay maybe $50 and a 5 minutes trip to the local GM dealer. An aftermarket system is way more than that and you will end up with an aftermarket system.
Looks to me you actually want the aftermarket system, not just want the HU working.

can they actualy unlock the HU in there if it wasn't from the years that used the same part number ?
i know there have been some who have installed Class 2 data in there Class 1 data units bud didn't they need to wire some things up ?

I actually WENT to the Dealer and he told me they Couldn't do anything with the radio because it wasnt the radio that went in my car. The Dealer is the one that Suggested getting an aftermarket radio installed or to get the RIGHT HU for my car if I wanted to stay with what was already there. EITHER way it was going to cost me MORE then $50 . That is what started this whole thread was because the DEALER Told me to get an aftermarket radio installed.

03-30-12, 08:59 PM
Exactly^^^^

They know that only '98+ cars had the Theftlock, but ONLY the HU is different, the car data bus is the same. So you can install a '96-'97 (non-theftlock) HU in a '98+ car no programming required or you can install a '98+ HU in a '96-'97 car just like you would in a '98+ car (with the VIN clear done).
OK too much reading just print this and show to the technician:

When connecting the TechII to a '96-'97 car to clear the VIN from the HU build the car as if it was a '98+ car (use Eldorado or DeVille) either by manually selecting the year, model OR you can use a VIN of a '98+ vehicle. Do NOT use the VIN of the vehicle you connecting to!
The clear VIN menu should be now available when selecting the HU (IRC).
Proceed as if you would normally do on a '98+ vehicle.

There is one catch with the HU you have, it is indeed a ‘98+ base model but sure hope is not from a Catera as it won’t work, it has to be DeVille/Eldorado/Seville ONLY.
