:D I just used this exact process on my TGP with the Factory CD player.
I needed to know how to do this and I found pieces of info on several sites including this one and w-body/tgp forum. None of them had complete information but I managed to peice all of them together.
1. Press and hold presets 2 and 3 for about 5 to 10 seconds until you
get 3 digits on your display. This is the first 3 of 6 digits you will
need, so write 'em down. (mine were 881)
2. After doing step one and writing down the code, immediately press the
AM/FM button to get the last 3 of the 6 numbers you'll need, and write
'em down. (if you wait too long between steps 1 and 2 and the LOC code
displays again, just start over). (mine were 322)
3. Call this number, it's a prerecorded message, so don't worry about
having to talk to anyone...1-800-537-5140. The voice will ask if you're
calling for Chevy, Pontiac, Cadillac, etc... When you hear this,
press 1 for chevy, followed by 02107and hit the * key. (i.e. 102107*) He'll ask you for the 6 digit code that you've written down.(mine was 881 322) Enter that and press the * key. He will then give you a code,(mine was 810 891)
4. To unlock the radio:
A. Turn the ignition on.
B. Press ?SET? (000 appears on display).
C. Press ?SEEK until the first digit of the code appears.
D. Press ?TUNE" until the second and third digits
E. Press "AM-FM" (000 appears on display).
F. Press ?SEEK? until the fourth digit of the code appears.
G. Press ?TUNE? until the fifth and sixth digits of the code appear.
H. Press "AM-FM". Now the radio can be turned on.
*writes down Tim's code and makes plans to steal the CD player*
-I KID, I KID!!! :)
I've never had to go through all that with any tape or CD player in any of my Pontiacs. Usually, I plug it in, it says LOC for a split second, and then it's good to go.
And unlocking was so much easier on the pre-'89 Gen I steering wheel controls. All you had to do was hit mute & RCL on the steering wheel at the same time, and presto. Your stolen -er...bought radio was good to go!
I am not worried about someone stilling it. I doubt the stupid code is a deterient for anybody cause everyone knows you can get them unlocked. Who else would want a factor cd player except a TGP owner and once they put it in they could go to the dealer anyway and get it unlocked.
Besides that stereo is not in the TGP that I care about. Its in the car I just bought for $500. I might give it to my brother or sell it, Haven't decided. (any bids? ) Just put a rebuilt turbo from turbo chargers.com on it.
The mute trick did not work on mine and neither did removing it and putting it back in.
Actually, those things seem to go for a decent chunk of change on eBay. A non functioning CD player went for $40. And a supposed funtioning one is at $100 right now! I won't pay that much for a 11 year old CD player even if it is working because it is destined to go out at any moment. I'd rather get them cheap and have them refurbished. I've got two that need to be refurbished (one of which was the first and only one of this era that I found at a junkyard still in the car! Bonneville SSE). I have a newer style one from a '95 Bonneville that still works with these controls perfectly. Everything is functioning on it. Skips FAR less then most every aftermarket unit I've heard. Even THAT one didn't need to get unlocked.
As for the mute trick, I was saying that works on the GEN I controls only, not the GEN II. I use to have to do the Mute/RCL trick on my old '86 STE all the time.....because the damn stereos went out so frequently :x
Tim, you just became my best friend!!
BTW, this should be a STICKY!!
Glad I could help.
