Rand McNally 7720 7-Inch RV GPS
Last November, after buying our Greyhawk 31SS, I ordered a Rand McNally RVND 7720 7-Inch RV GPS. I looked at the Camping World version, but it cost more and I'm not specifically looking for Good Sam RV parks. My son used the motorhome during the winter. On a long trip to south Florida, he took the GPS along and reported that it didn't work very well - slow to notify of turns, locked up repeatedly, etc. I've used it one time in my Jeep on a 300 mile trip with no problems at all. I'll admit that I was familiar with the route, but it never failed to give me timely, correct directions. That speed limit thing is cool. Never missed a sign. Also, I discovered that my Jeep speedo reads 5 mph slow.
So, anybody out there have one of these things? Hows it working for you? Could it be that the overhang interferes with GPS reception? We'll be going out next week and giving the GPS a test.
