I have had my RV760 for a month or so,let her show me the routes for about 1500
miles.I have found that as with any GPS,it's a good idea to check the routes she wants to send you,with a paper map.She took me on a round about way one time.
I'm happy with the unit,lots of built in information.I downloaded and installed the Passport America app,there is already something like 14000 RV parks preloaded.
I got the RV760 to replace my nuvi 350 that was getting senile on me.
Be aware,if you purchase one,you may need to download the newest map update,which is free for life.
