2x on CoPilot. I loaded the App to my cell phone then had DW drive me around in the car with it on to see how it worked. I was satisfied so I bought the RV addition for $29.99. The RV App is a one year subscription.
In my case I bought a Samsung 8" TAB A (on sale) and loaded the RV app to that.
I also picked up a dash mount and tab holder from ProClip USA.
One thing though, I had to do some research and spend a couple of days figuring out how to get it to work.
Forgot to add...I always carry an Truck Atlas and fold up paper maps. Look up my route the night before and check for problems.
