When I upload custom routes made in BaseCamp to my 660 Lane Assist doesn't work. Is there a workaround for this? I've read some people have success if they recalculate the route or reorder waypoints once in the zumo but this hasn't worked for me. I read one post that said inverting the route, then inverting it back worked. All that did was really screw things up.
What has worked but is a pain is to import all the waypoints then built the routed on the zumo.
Thanks.
