I'd beware of Best Buy, especially if they are doing custom work. I used to work at Best Buy a few years back, and I've heard of all sort of stupid stuff they did when trying to do custom work...ie: brake lines drilled, fuel lines...etc.
No special wiring needs to be done. Only the right interface is needed. Check through this post, http://www.bonnevilleclub.com/forum/...ic.php?t=33586
and others.. There is an adapter out there that will directly hook up to the bonneville and continue to allow the Onstar, and door chimes to work. I'm sure they told you that you have to have radio re-wired to the trunk. I have an '04 and once I had the adapter it worked like a charm with the chimes, retained acc. power, and what not. I had about 5 different places tell me the same thing. But once I did my homework on here I found out the right way to do it.
However the problem is that most car audio places including high end places aren't aware of this adapter. I got the adapter from www.lafayetteradio.com
. Although I did the install myself, you could still get the adapter and then give it to a place to install. That will save you a ton of money in custom labor, since the interface just hooks up directly to the factory ribbon cable.
