This is such a disappointing radio.
1. No way to manually enter phone book names so forget about caller ID working unless you have a very specific phone.
2. Only phones with OPP can transfer addresses.
3. Front / rear speakers can't be faded if you have On-Star.
4. Navigation voice commands come as I pass my turn.
5. Won't pair with my factory CD changer.
6. When I have my 3 registered phones in the truck before starting the engine, only the phone registered as #1 works through the system when any of the 3 receive a call .
