Regarding the nav screen issue. I had the exact thing happen to me at 22,000 miles so way to new to be having that problem.
Mine would rise up stop and immediately lower down.
It was covered under warranty but the dealer said the power supply box had the correct input but no output...whatever that means.
They replaced the navigation power supply box assembly, which solved the problem. This was a $1,265 repair that I am thankful was under warranty.
Hopefully, yours is under warranty as well.
Good luck.
