In preparation for a long ride I made a short panned route using myrouteapp.com in order to learn my way around the nav5. I got the route created and imported to my nav 5 just fine. I was able to follow the route. My problem came when halfway through the route it took me down a gravel road I chose to go around. The gps the rerouted me to the main highway as the fastest way to the destination. I could not find a way to the resume the route halfway through, the GPS would only route me to the beginning or end. How do I go about resuming the route while already part way through it?
