Re: 2014 Summit NAV issues
I have not had those issues but some folks have mention the radio preset issues and mentioned that those are tied to the seat/mirror memory.
I don't know what's involved with flushing it all out but I'd tried getting things set in both memories and put something a little different in each and make sure you can recall each set. That might make things stick.
