These problems occurs when I am using saved courses:
1. Sometimes the text prompt at the top says turn left in X feet but the map clearly shows either straight ahead or a right turn.
2. The screen is frozen - I didn't notice it had frozen so was about to take the left turn that it indicated (I hadn't noticed that it was left turn in X miles and X hadn't changed for awhile!) Luckily, I was with friends and followed them on a right turn.
3. I get a U-turn in X miles and when I ride the X miles, then I get a U-turn in Y miles.
I just realized that all of these saved courses were created with Ride with GPS - if that is a contributing factor.
Thanks for any insight/help.
