What do most veteran RV'ers use for navigation? Because I have heard of issues with the Garmin style dashboard navigation devices I am downloading trucker apps to my phone and having some luck. But...
I have an older Garmin RV 660. I know there are some new ones out, but I'd say it is about 95% accurate. I use it in conjunction with the Rand McNally TRUCKERS atlas. I have the laminated edition. It is really helpful. With the laminate you can draw your route on it with a board marker. It gives a wealth of information. As far as the Garmin goes, I know they have new models available.
