I'm wondering what people's experience is with chimes in the c6 after installing an aftermarket headunit?
I installed my HU using the Metra GMOS-100 and door chimes work, but the DIC chimes, memory seat chimes and gauge warning chimes do not sound. It's a bit annoying. Do they work with the OS-2BOSE or any other interfaces?
I've had nothing but trouble from the Metra interface.
Just had my car recently upgraded by forum member Pentavolvo. He used the PAC harness, C2R-GM24. The chimes when starting the car are fine, but the chimes for the seat memory while there are muted in comparison. Overall I have no complaints or issues, just something I've noticed in my short time in the car since the upgrade.
