We've had one for a couple of years now. Bought it for the larger screen and low clearance avoidance (important when your rig is 13.5 ft tall). Does a pretty good job. It can be easilty switched between car mode and rv mode, so useful in situations where we're either towing and not. The bluetooth connectivity can come in handy when paired to my iphone. The ability to display weather radar is useful, but kind of crude. Usually when we want to see what we're heading into, my wife will pull up the weather radar on our iPad. All-in-all, it's been good for us.
