My RV came with an indash GPS that is a Tom Tom - not an RV specific GPS but a car GPS. The Tom Tom has more than once told me to turn right when I should have turned left and then directed me into a maze of streets or better - a parking lot - to turn me around and put me in the direction it should have told me to turn in to start with. This Tom Tom GPS also is supposed to have built in traffic using the traffic broadcast by the radio traffic data system. It does not work. Tom Tom told me that they no longer support that - they said this and still do from when the unit was new two years ago. The only good thing that I find about the Tom Tom is its ability to hold many "itineraries" with easy access and on the fly changes. But that also has its problems. My first GPS was a Tom Tom and I soon put it in a drawer and bought a Garmin. The GPS does not have lifetime maps and Tom Tom makes no offer to sell that feature separately as other GPS manufacturers do. Tom Tom wants more for a one year map subscription than I paid Garmin for a lifetime map subscription. I would not buy another Tom Tom - RV or not. Now I am not saying that the Garmin RV is any good but definitely not Tom Tom if it works like all of their other GPS units have worked.
