Onstar Compatible with XM or DVD Players

[Buckeye Hummer]

Purple Prowler, FYI, I researched satellite radio last year and decided to go with Sirius over XM. Reason 1: XM does have some commercials on the music stations; Sirius is commercial-free. Reason 2: Satellite reception is better with Sirius (based on my tech's experience and that of numerous articles I have read).

My Sirius sattelite radio was hard-wired into the factory unit. The steering wheel volume does indeed work. The only slight problem we had was when the key is turned off typically a cd or regular radio would continue to play until the door is opened. The sat. radio turns off when the key is turned to off. This is minor but something you should know. I have been very pleased with Sirius so you may want to give them consideration. Here is a pic of the unit, which is double stuck (not drilled). I use my remote to change the stations.
