Randalface Posted October 22, 2013 Report Share Posted October 22, 2013 Well I updated my unit (F900BT) to the latest software and firmware and now the nav will not work at all.. If I hit th map button, i am sitting in a river somewhere. Anyone know how to fix this? I also tried loading to old maps back in from the backup I did and that didn't work at all.
