I have seen many great installations of nav systems here in the H3. My question is where did you guys get the adapters or harnesses to interface with the stock wiring? My question infers that I want to keep door chimes and other stock features while using an aftermarket nav system (Alpine or Pioneer) in the H3.

There are 2 modules you need to keep Onstar and door chimes working.Pac 0S2 either bose or non bose depending on you radio.Plus you need module CM1 for the door chimes to work.These are very easy to use they plug rite into the factory harness.One thing to keep in mind is you need to connect the 2 or 3 purple wires from the factory harness together.Once that is done you can just plug aftermarket radio in and everything should work.
