I have installed a factory nav radio in my 2008 Silverado that was not so equipped. I added an aftermarket amp, used wiring harness OEM1 from PAC Audio. I now have the sound and nav working. But, I dont have door chimes or Onstar voice. I still have a VCIM cable with red and black leads on one end and a plastic GM connector on the other. I have another harness which plugs into the back of the radio fine but has anRCA end left unattachedand a green wire also coming from the plug.I also have a camera and short harness sitting on my lap. What have I missed? Thanks in advance for any help.

maybe this diagram will help you. I don't know what harness you are using or what kit you got them from. the chimes come from the factory amp but maybe the integration module you are using is supposed to supply them? maybe they need to be turned up?

according to pac the front left rca out from the oem-1 should carry your chime as far as the extra plugs not too sure the instructions on the web are very vague and i dont have one at work to look at
