The best feature he enjoys using is the Bread Crumb feature, which allows him to mark off road trails, which is great because he works in the oil fields so there is a lot of off road driving with bad directions from dispatch, this helps cut down on drive time and getting lost

I have the 520 and it will take you 15 or more miles in the wrong direction only to show you a loop at the end of the trail

For such a highly touted unit the 720 loves to send you in the wrong direction only to request you make a U-turn once you are 10 miles out in the wrong direction.

It will ignore the correct ramp and instead send you to the next exit only to have you get off, turn around, and re-enter again going in the correct direction it should have sent you originally.

to many wrong directions and go around.
