I have it on my phone but don't use it. Like afidel said, it's not user friendly. I use RV Trip Wizard to plan my trips and then recreate the exact trip in google maps and text the trip to my phone so I can use it to navigate. If you try this, don't use "My maps" in google. It isn't for navigation but just regular google maps and text it to your phone.

I asked him to do one thing and he didn't do any of them.
