2000-2003 factory replacement
 

Found some good info here at Soundgate on replacing factory units. Bose
Its a pdf file, scroll to the bottom for notes.
I think I saw a kit once that would let hide the head unit in the trunk?

For just adding to your existing system, see my post towards the bottom of the page, it may convince you to leave the stock system in.

I believe there are adapters available now that allow you to use an aftermarket radio with a special interface box on it such that you will not need to keep your stock radio hooked up.

I haven't heard of that on the 2000+ yet. At least not on the SSEi, as my understanding is that in order to keep your memory seat, chime, an a few other things you need the radio in the car, somewhere.

If you found something, post it. :!:

:D

I'm trying to get all the 2k+ info into one place, as I find interfaces and tips I'll post them here. It seems the class 2 data bus is a pain to work with but they did come up with a good ifx for the corvette? Maybe ours is compatible?

Rats. I think you are right PDad...Here is a website that carries some Class 2 adapters, but they can't guarantee compatibility with the Bonnevilles.

BUT it might not hurt to give them a call, as I know they are always updating the software in these modules to work with newer cars....and who knows when that website was created?

Here is another company that makes interfaces. You may also give them a call to see what their thoughts are.

I'd be curious myself to see what they have to offer.

This one does calim to be compatible with the new GM interface protocol. Don't know for sure, but we will soon. (At least I will, and will share my experience)

Got a few emails back about the Class 2 data bus and availability of a bypass kit.
The long winded email I got from Gm Performance suggested the corvette interface may be adaptable? Anyone have a Corvette interface to try........sheesh :P

I've been thinking that if its a serial "token ring" communication network that the stereo must have an 'address' and is being polled by the controller. If its not there then it skips in oposite directions to talk to the other devices (ie door module etc), if two devices are gone then the whole loop crashes?
What we need is to figure out how to emmulate the address and secure the network, that way if a device fails the rest of the loop is still intact?

Any thoughts???

Why not go for the relocation harness? I would'nt think it is a big deal to just relocate the factory radio to the trunk or other area, and you would be able to install any aftermarket HU. Right? When I was getting my Pioneer installed the shop told me that I may need the relocation harness, and they would'nt know until they pulled the stock radio out. Luckily I did'nt need it, I understand it costs almost $200. I did loose the chime function, but I got over it.

WRONG- BAD INFO , my 01 GM Bose deck is sitting in my closet collecting dust for many months now. No problems here, My installer didn't even tap into the ribbon, sitting unconnected, he taped into the steering wheel harness for power and accesrory and such.

Only lost Door chimes and the abailty to talk back to Onstar, oh and the steering wheel controls which I regained controll of.

Don't let an installer tell you it has to stay in the car!

Taylor,

When I had mine installed one installer told me $350 to install my $300 head unit becase the OEM HU would have to remain in the vehicle, and the harness costs $X blah blah. The installer I finally went to said that it varies from year to year and he was'nt going to know until he got behind the radio what would happen. $75 later everthing is fine, but I would'nt take that quote with a grain of salt.

the type of radio you have is what determines you will have to keep the radio in the car. if you want to keep all of the car functions you will have to relocate the head unit and mount a speaker under the dash for the door chime and low fuel chime. i just pulle dth deck and lost the chimes but some cars will loose more then that and if that is the case i would just relocate the deck to the trunck. the harness to relocate is about 100.00 but i would not pay 300.00 for it to be done, the people i bought my headunit from would have done it at 75.00 with cost of the relocation kit.

Who needs door chimes? Not me.
I hear there is something called GM Chime that can re-activate it with out the stock HU in the car. Never really looked into it.

Home Made Wiring Harness
 

I have a 2000 Bonneville and I recommend relocating the factory stereo to either the trunk or under the passenger seat to anyone who has a 2000 or newer Bonneville. I first purchased the GM07 and GM07R Scosche wiring harnesses. The first harness is the one that plugs into the car and the second harness is the one that plugs into the factory stereo. Basically you can make your own relocation harness for real cheap. I took some three foot lengths of cable and connected the two wiring harnesses and made them into one big relocation harness. I then cut a flap in the carpet under my front passenger seat and tore out the foam under the carpet, set the factory stereo in the little hole I made and connected the home made wiring harness. The carpet flap covers the front of the stereo enough so that no one can see it under the seat. Then (the hard part) I had to replace all my speakers with Rockford Fosgates and added amps, an XM tuner, and my Pioneer head unit. The draw back to all of this is, I had to run power and ignition wire up to the front of the car to hook up to my new stereo (not to mention the three sets of RCA cables, two sets of speaker wire for the doors, IP Bus cable for the XM tuner, etc.). To retain your door chimes and warning tones, I just taped into the factory speaker wire going into the drivers front door and attached a cheap CB external speaker. It's pretty simple to explain. The hard part is actually doing it and finding the time to do it.

Re: Home Made Wiring Harness
 

Sounds like a lot of work for chimes... glad I did'nt do that...

Factory Stereo Needed
 

The work I did to relocate the factory stereo was not just to retain the door chimes and warning tones, but I really wanted to keep the factory stereo hooked up to the Class 2 Data BUS system in the car. Without that factory stereo hooked up to the system, the system may malfunction when something goes wrong in the car. It's a big safety issue in that your airbags MIGHT not inflate at the time of a crash. That's what GM told me, thought I don't know how much I believe it. Also, you can look around all you want, there is no Class 2 Data BUS OEM interface box to hook up to the car so that you don't need to relocate the factory stereo. I looked all over and talked to many-a-tech support. They all told me the same thing. All 2000 and up Bonnevilles are an exception to GM's Class 2 Data BUS system. Bonnevilles use a 32 pin computer chip-type plug. All other GM cars pretty much use a 24 pin wire harness for their Data BUS system. I spent days researching this with numerous manufacturers and all said the same thing. But hey, the work was worth it for my peace of mind.

im not arguing: Do you think if there was a problem with any other system that was depenand on the GM-IP bus system there would be some error indicator, idiot lamp, SES, anything? I have had a Pioneer HU installed in my car since early 2003, no problems, no warning lamps, and no codes (according to the scan tool). I have'nt used the airbags yet, so I am not 100% sure. :roll:

I was told the same thing by different shops, never contacted GM directly (did'nt think they would be too keen on helping me replacing my OEM radio), that if there is going to be a problem you will get some sort of SES/SEV light within 30 days or there abouts: never did.

I think it would be a foolish design flaw to incorporate life saving features (SRS) into the factory radio...but hey, it is GM..

Idiot Lights with Factory Radio Removal
 

No, it's OK. I wasn't implying that you were arguing. As far as the warning lights, here's the thing that happened to me. Normally, with everything good in the car, when you crank the car over, no lights come on. But, when it's done cranking and the systems are all initializing, all the dummy lights come on. However, I removed my radio once and started the car without the factory radio plugged in. Apparently, this is a big no no which I found out too late. Now, even though the factory radio is still technically connected... When I crank the car over, the Service Engine Soon light comes on. And when the car starts and all the systems are initializing, all the dummy lights come on EXCEPT the Service Engine Soon light. In other words, the Service Engine Soon light comes on when you crank the car, but goes out when the others are supposed to come on. When the car is running normally then after the start, no lights are on as if everthing is normal. I took the car to a dealership and told them the problem. They hooked it up to a code reader and said everything was fine. They look up the light's behavior in a tech manual and supposedly the manual says it's normal for the Service Engine Soon light to do that. So, either the dealership is lying, or Pontiac is retarded which that feature. I just want the Service Engine Soon dummy light to behave as it did before.

I have never experienced any of the ailments you are referring to. With the factory radio, with the aftermarket radio, and with no radio.

Must be trim level specific, or specific to certain years.

i have never seen any of this either

Pisses me off
 

Well, hopefully someone someday can help me. I don't know what the stuff is either but it's starting to really piss me off.

UPDATE: Metra now has a kit for the '00+ cars!

www.metraonline.com

Part is the "GMOS-05 Dock-n-lock Interface"

Go get it guys! :D

help i do not see what you are talking about. i even put the part number in and still did not get anything.

Call them directly, its a brand new part.

what is it? a dash kit, a wiring harness....what?

Wiring harness and interface box for '00+ Bonnevilles to install a aftermarket radio.

Will this allow you to have an aftermarket radio and still retain all the functionality of the car such as door chimes and onstar without relocating the factory radio?

Anyone ordered/recieved the product ?

Thats what I've been told....go to Metras website and give 'em a call, I'm sure they will know what it can/cannot do.

hey i have a stock cd player wit a tape deck that came with my car. my grandmother has the exact same car but her's just has a tape deck that does not work. does anyone know if i can put my old radio in here car? i know that mine is the "robbon" but i have not pulled hers out to see. i just wonder if her's will be the old style plug? she would really like to keep the stock look to her car and she knows how to use it already if you lnow what i mean....

HARNESS FROM METRA
 

METRAS ELECTRONICS WILL NOT HAVE THE CORRECT WIRING HARNESS WHICH WILL NOT EFFECT ANYTHING OUT TILL THE END OF THE MONTH. I SPENT A HALF HOUR ON THE PHONE WITH SALES THE TECH SUPPORT.

Cool, at least its on the way.....

Did anything ever become of this? Anyone ordered and recieved one, or even know if they released the harness?

I talked to them and there still working on it. There also looking for dealer intreste. I hope they get it done soon. Its the GMOS-5 Lock & Dock.

I have a 2001 Bonneville SE. I was told all the same stories. I have replaced all of the OEM audio equipment with aftermarket. I used a Scosche wiring harness and install kit. The only problems I experienced were that the accessary wire (red) was not an accessary wire (didn't do anything at all), the install kit barely fit and I lost my door chime.

To fix the accessary wire problem, I had to splice into the ignition wire behind the steering wheel.. (not difficult if you know what your doing)

By removing the brown dimmer wires from the harness and detaching the OEM harness and antenna plug from the clips inside the back of the dash where the OEM radio plugged into, made just enough space to install the aftermarket DEH-P6300. Still a tight fit, but it looks good.
