I bought the RM 7710 last year and so far it has worked nicely. I like that it is specific to your rig when you are getting directions. Vehicle height length and weight are all considered. Additionally it has some neat POI's. Flying J/Pilot and other fuel stops...wal-marts, are one key stroke. My only complaint is that the screen can be hard to read at times because of the background glare. I did buy the anti glare screen and the hood but they are not that effective. Overall I love the unit
