I have tried to download a route to my Garmin 660, having followed all the advice and tips already given on here.
However I only get straight lines from one point to the next despite having placed waypoints etc.
Some trouble, any solution?
just wish my old zumo 550 hadn't died. CaN'T GET AWAY FROM STRIAGHT LINES ON THE 350!
Once the route is loaded on the Zumo, change the navigation preferences from fastest to shortest which will force the Zumo recalculate the route, to follow roads, then change back to fastest.
