GM's Radio with XM from Tahoe/GMC

[Buckeye Hummer]

prplprwlr, Since you want to stick with factory stuff I suggest buying the radio and then having a local pro install it. They just have to wire it properly to an antenna or they should be able to rig a new one.

Even though you want the factory look you might just take a few minutes to check the aftermarket stuff. It is dirt cheap because they only care about the service cost so you can get some very functional equipment for next to nothing and I also think the install will be more practical than trying to fit the GM xm radio in, which could be a little off causing a plate to be built so there are no gaps. At that point you're doing a custom install anyway and should probably stick with aftermarket.

Just my opinion, good luck!
