This is not limited to Zumo...since we're all probably using the same mapping software (V8 Mapsource), I'd like to throw out a general use question: How do you plan an extended trip on your software to transfer to the unit?
Here's what I did last night...used the routing tool and marked my route with waypoints on key segments of the roads I want to travel. I found you have to be careful doing this, as the routing tool will take you ways you don't really want to go if you don't mark points close enough to each other, particularly on certain roads. I then used these points to "plan a route". When the directions are given for that route, it does some funky things during the route, or at least it's saying it is.
Is there a better/easier way to do this? I have a 2820, but that's really irrelevant if you do the routing on the PC then transfer the route.
