I log on to MyDrive. I plan a route from Parsippany NJ USA to Woodbury NY USA. I then click on Send route to Device. The result on the device is a route from 7th Avenue Manhatten, NY to Woodbury. I reverse the route on MyDrive and click on send route to device. The result is a route from 7th Avenue Manhatten to Parsippany NJ. On the device it says you have added a new destination as though it had not recognized transferring a route.
I know I have copied some routes but this seems very hit and miss. Is there a proper process? And why when you are planning a route cant you just click on the destination and say use this as the end point?
