We have the Garmin RV 760 now. It is great if you only travel on interstates but if you travel on any two lane roads you need a paper map. I can't even count the number of times it would have (and a couple of times it did) get us lost to the point we had to turn around and take a different route. Last week we traveled from Albuquerque to a spot just south of Taos, NM. I knew exactly where I was going but wanted to see how the Garmin would route us. If I had followed the GPS we would have ended up at one intersection where we were told to make a left turn. Impossible with 59 ft. of truck and trailer. It also took us 30 miles past our destination and then had us turn around and go back. It kept trying to get us to turn on dirt roads that led nowhere when we were on the two lane highway on which our property was located. Just saying.
