I'm using Topo Australia maps and have created a route using Basecamp. I've sent that route to my 1390 GPS. I can't figure out how to go to and view the route on the GPS. Help!
Unfortunately the Nuvi 1390 does not support routes. In this case I'd recommend creating waypoints in BaseCamp for the destinations that you are interested in, transferring them to your Nuvi and then navigating to each in turn via the Favorites menu.
