'07 H3; Aftermarket radio installation

[96TL]

I'm ordering the Panasonic CQVD6503U.

I just want to make sure the door chimes and OnStar both function. I also want to be able to distinguish the power, ignition, and ground wires easily and w/o hacking the OEM wires.

This is the stereo I plan on installing.
