I think the harness for that one is the GMOS-LAN-01 harness. Says its for 09+ aveo and retains all onstar features as well as warning chimes. Expensive at $90+ but does the job and the factory Xm might be able to be reused ull just have to find out by removing the radio. The aftermarket radio will need the XM tuner anyways which comes with a satellite antenna.
