I have the Axxess module to interface with my OnStar. Granted I don't have the stock HU, but there is a dial on the side of the module that adjusts the volume of the chimes.

Dude two good interfaces are the PAC OS-3 adapter or the PAC OS-4 adapter. Whichever one you want is fine jsut make sure you pay attention to whether you have Bose or not. They come ready to connect to your HU and are all over online, including Ebay.
Did you ever figure out a way to keep the factory chimes?? You're right, the PAC chime module is HORRIBLE!i have bose and pac os 4... the after market chime SUCKS. I wish I could change back to stock chimes... anyone ever figure out how to change those sounds?
