Can anyone help me figure out how to transfer a route from my MapSource program on the computer to the Zumo 550 GPS? When I click on the send to device button in MapSource I only get the option for transferring a map. The check off options for routes, tracks and waypoints are greyed out. I want to be able to design routes on the computer and transfer them to the Zumo and not be limited to designing the routes on the GPS itself. Im worried that I got the wrong GPS> Help. Thanks.
