It sounds like RV version has some of the same problems as the truck version.
It's hard to drive and use paper map. The phone is bad enough. While I just listen to it, when someone tries to call or message, it kicks map into background and mutes it.
Many times, I just use truck GPS to display map, without selecting route. I use the tools menu, to minimize sub menu and pop ups.
I first got cheap gps, for speedometer, after replacing third Speedo gear on my 90. About every other time odometer rolled over, it would start skipping around. That $29 TomTom was easier to use and didn't send you down rivers. It seems most of development has been geared towards ads and sponsors.
