I searched the web and forums for this answer but got a lot of random information. I used to own a 2012 F150 with a pretty bada$$ Nav unit. Check the weather, stocks, sports etc. I was wondering if i could do any kind of update or upgrade for my Nav unit. Obviously i cannot put another nav unit in since my AC is tied in. The graphics look terribly old and doesn't really have any features. Any thoughts?? Thanks guys
