GM On Star and the Infill G4
I was trying to price some of the installation pieces I might need before I placing an order (wiring harness, trim kit, etc) and I got a response from a dealer stating that installing an aftermarket stereo will render the On Star unusable as well as the warning chimes (e.g. door open, key in ignition, etc) in my 2007 Saturn Vue.
Does anyone here know if this is true, or if the G4 addresses that? If it is true, does this apply to all GM On Star equipped vehicle? I don't care much for On Star, but I don't think my wife would like me crippling all of teh safety chimes.
