When engaging Telematics, my DIS is showing "Onstar Advisor" but there is no sound...

I guess Telematics and RNS-E are not compatible. I'm not using onStar anyway, just want to confirm if it's true or I missed something during installation...


Thanks

OnStar is working fine with the RNS-E. You have to connect the OnStar interface like a normal phone kit. If you didn't order an adapter harness with phone support you may not hear any sound. If you adapter incorrectly shortens the mute pin to ground, the RNS-E will always be on mute.

That's probably it... I guess I need a different adapter harness that supports telephone. (I'm planning to put BT module instead of Telematics)

and if in the future i want to add glove box CD changer (if I find one) i need harness that supports all these modules, right?
