I have a 2011 HHR LT. The factory radio is bad. I want to install a single din Pioneer unit. I bought the connector adapters and the Scosche chime interface. I have torn my dash apart and can find where to plug the interface into the main harness. What chimes will I lose if I simply bypass the interface? Door chimes, keys, etc. I can live without but I don't want to lose any emergency warnings.

Thanks
