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.

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!
