Can you pick a different route than what the Garmin chooses then as you approach your destination turn it on and go from there?? I've tried this and it appears that my Garmin trys to get me back on the original path it picked even if that meant sending me back the way I just came. Doesn't it know where I am and recalculates a new route to get me to the destination I had originally asked for?? Thanks, Clint
