Hey All, My 08 acura mdx navigation display screen is on the fritz. It started by only showing the backup camera picture and it being stuck on it sometimes even in drive then it would go blank. Now the bacup camera wont come on and the acuralink system tries to boot up and I can sometimes almost get the security code in before it freezes and shuts off. I leave the unit unplugged now under the drivers seat but the time on my clock is not right and cant be changed without the display screen working. Do I need a new computer under the seat or can it be updated? Or is it something else causing the issue? Thanks for any help
