I agree with the previous posters about Copilot. After researching the Garmin and the Rand RV specific GPS's and the issues folks on this forum were having with them I bought the Copilot APP for my I phone for $6.99. My thoughts were if I spent $6.99 and I was not happy with it not much lost over spending $400 and not being happy with it. You can choose from car, MH, motorcycle, bicycle,or pedestrian. It also allows you to avoid propane restricted tunnels and you can also input your MH height for low bridges. The thing I like about it is when you plan a route it will give you alternate routes and you can look at the live traffic which shows congested areas which help you determine your route. It also alerts you when you go 10 miles over the speed limit. I downloaded the free version first when I was in Hawaii 2 mos ago but was not impressed with that over the Google maps. I am very happy with the premium version.
