According to the owners manual in my Dad's pontiac Montana van, the onstar systems are locked to the vin number of the car and can't be swapped to a different car.
Well, I bought a Onstar kit online thats designed to be installed in a Blazer. As an upgrade at the dealer. Although when you activate a unit, it calls the Onstar service center and you have to provide the VIN, I think that the unit could be reinitialized with a new car/VIN if the center doing the install is a GM authorized Onstar dealer.
<BLOCKQUOTE>quote:</font><HR>The problem is that the onstar is wired to everything including the air bag, door locks, radio and there is some kind of Gps unit because they can tell where you are.<HR></BLOCKQUOTE>
Well, it uses the UART signal from the SIR system (pin 9) to tell if the SIR system deploys, and the unit itself plugs into the back of the radio where the remote CD/Changer would go, then the CD/Changer plugs into a pass-thru. Its actually a simple harness all things considered, I was just curious if there were any pitfalls like it requiring some sort of unusual information like the newer overhead consoles do.
Whats wierd is that this kit has no provisions for remote unlock.
