I assume you are aware that the nav system has 2 modes-North always up and direction of travel always up. My wife prefers the latter. The mode can be changed by touching the screen on the north arrow at the top, left corner of the screen. We prefer the split screen which shows map on left half of the screen and the next turns on the right half. Then shows turn detail when you arrive at the next turn. My wife says it does tell her the wrong direction at one intersection on a frequency trip she makes. I have not tested that myself.
