What's up guys, Just got a new AVIC X920BT installed today in a 2007 Avalanche.. The problem is that most of the settings are greyed out. I do apologize if this has been covered, and I did try to search for my issue, but couldn't quite find a match. I am unable to change any system settings, including the time ( cant even get to that point). I already updated to the latest firmware, but still no change. Everything else works as far as I can tell, but something is surely wrong. I paid $345 bucks for a "professional" install with a back up cam and an Axxess ASWC (steering wheel remote adapter)
