After performing the 18.45.01 update to my 2017 2500 I developed a problem with the navigation system. The actual navigation function works fine, but the "next turn arrow" is off by 50 feet on the nav screen and on the evic. When arriving at the appropriate street to turn on, the navigation voice prompt correctly says "turn right (or left) now". The next turn arrow however indicates the turn is still 50 feet away. It is not a matter of the turn arrow being slow to respond because the arrow is 50 feet off even if you are stopped at the intersection at which you are turning. This is very annoying when you are driving in an unfamiliar city where the intersections are so close together. I have performed the soft reset of the radio but the problem still persists. Does anyone know of anything else that I might try?
