Okay so first things first.. my new factory navigation came out of a corvette.. technically same radio as the pontiacs. I installed it the other day had it unlocked at the dealer and installed my ACDelco 15821030 antenna.. so my problem is the navigation has a red slash through it constantly and acts as if there is no signal.. the steering wheel controls will not work.. the Navi radio will not display time nor will my dic display the date.. any help here would be greatly appreciated!!!
