Patrick, I could write lots to explain all of what you want to do, but maybe showing you would be easier. Its very easy to do routes in Mapsource for your GPS and download especially if you were shown how. I live close to you in KK . If you want to do this e-mail me at
jd100@diginet.ie.
By the way did you not get a Mapsource DVD with your Zumo ? to load on your PC ?
Cheers
John
