jtemail Posted April 4, 2003 Report Share Posted April 4, 2003 Just bought a 2004 Grand Prix GTP yesterday. It has the premium audio system and the competition package. Anyone got a good contact on how to add the factory XM radio option in after the purchase? I imagine I need a different head unit and an antenna. Anyone know the part #? I don't want to pursue aftermarket solutions until I know I have to. I want to know what it would cost to do it GM's way before making that decision. I have aftermarket units in 2 other cars.

Brian P Posted April 4, 2003 Report Share Posted April 4, 2003 Have you checked with the dealer? Odds are they're the only ones that will be able to do it, especially with the warranty, they probably won't just sell you the equipment to install yourself Quote Link to comment Share on other sites More sharing options...

no1kicker Posted April 4, 2003 Report Share Posted April 4, 2003 Wonder if the XM unit would work in a pre97? Quote Link to comment Share on other sites More sharing options...

LukeZ34 Posted April 4, 2003 Report Share Posted April 4, 2003 If i remember right, it's a $350 option on the new GP.. kind of expensive, but almost worth it to have it all factory integrated. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted April 4, 2003 Report Share Posted April 4, 2003 The new GM 2-DIN radios need to be programmed with your vehicle's VIN and options list in order to work, so it's not something you can install yourself. Quote Link to comment Share on other sites More sharing options...
