Anybody bought or checked out the new Zumo 550? Your thoughts on it? I'm thinking that the touch screen might be a little hard to operate bouncing around on a trail. But I like the large screen size and the fact that it has an built in MP3 player with Bluetooth for long road sections :lol: I was also checking out the Tom Tom "Rider 2"...but...and correct me if I'm wrong...if I used this in an event that waypoints were provided for a Garmin download I'd be out of luck...correct? (I plead total ignorance of such things.) Seems to me I've never actually seen either of these used for Dual Sport applications...how come?
