2000 cavalier stock stereo

A friend of mine was told that you need a special adapter to install a aftermarket stereo in his car. From all of my experience that is crap. He said there is something to do with the cars computer inside the oem stereo. I think this is all crap because the wire is the exact same as a 98 and the same as a 97 saturn. Any input on on this would be appreciated. I think the guy is only tryibg to make money.N.Helmsy

all gm vehicles i do believe after 00' need the stock h/u to remain in the vehicle.Quad L Handyman services

The vehicle has a class II databus system, do a search on this site to learn about it. In this vehicle, it is a real pain in the a$$ to do a cd install. The stock head unit must remain in the vehicle, and hooked up in the circuit, it just needs to be moved behind the right rear wheel well. It is moved with a harness available from many manufacturers, I like the Scoche GM06 ( www.scosche.com) , you will also need an antenna adaptor and install kit. When you move this factory radio, make sure it is strapped into place so it does not rattle around in the wheel well and that the power know is not accidentaly able to be turned on should the factory deck move or be turned on by placing an item in the trunk.Top Secret, I can tell you but then my wife will kill me.

is it possible to take the deck apart and just keep the circuit board in place?  wrap it in tape and stick it under the dash?  i was thinking of clever ways to install these dam things the other day.

Hey, what would happen if the head unit were to be removed? I dont know anything about this new tech. Just asking.1990 Honda Civic HB:

door locks shouldn't work, alarm shouldn't work, may send the computer into a frenzy.    Or it may just not allow the techs to diagnose problems.    IM not to certain yet, , but almost everything electrical is operated through the 1 data line.

oh wow. Thats retarded. why would they have something like that in their cars? I hope they plan on making some nice head units soon then. Like 70x4, 3 sets of rca outs, mp3 compatible. :) GM can handle that, they use the double din size receiver. haha. 1990 Honda Civic HB:

You can remove the stock radio with no problems.  The only that does not work after is the door chimes and onstar.  Your door locks, alarm and all other systems will work normally, as well as diagnostic computers.  I replaced mine in my 2002 sunfire and used a 2000 Tracker metra harness to connect it and it works perfectly. Its been months now and no codes have been set and my keyless entry still works.
