Hello all, I was wondering if anyone had an opinion on the utility of a 2008 AVIC F90BT v a 2013 AVH-7800BT in terms of overall functionality on back up cams, nav, audio playback, etc. I have both units. I bought the AVH-7800BT a few years ago and it is still NIB. Divorce, moving, etc kept me away. I know it is a single DIN, but I have these two and I thought I could make use of one in my Avalanche. Thoughts on which to choose?
