We are planning a three month trip out west next year. As a result, I have been researching GPS’s, and think we have settled on a Garmin RV 1090 unit.
The primary reason I like this unit is that, beyond keeping us off roads we should not be on, it is compatible with Garmin’s Basecamp software.
The software allows you to pre-program all the way points (campgrounds for example,
there will be about 30 of them ) points of interest (things we want to see along the way and once we are at our destinations) and tracks for things like scenic road trips. Once you have all the data entered, you can simply download it into the RV GPS and the motorcycle GPS and everything‘s all set and waiting for use. This is a whole lot easier than manually entering everything at the GPS interface itself.
