  1. Sometimes in the morning my Garmin nüvi 750 is getting confused by shifting car position some 50 yards to the left.

    Sometimes it doesn’t know local mountain road. That happened to us once, again in the morning. But in the afternoon on the way back the road was there on the screen and calculations were correct.
