I don't like the way that site changes the way Google maps operates from the way it operates when you're using it directly.
It may work fine after you figure it out, but if I'm on the road without Internet access I'd like to be able drop a route from MS streets & trips right into my GPS.
I'm still using a C330 (that doesn't accept user generated maps) with a sandwich bag when it rains.
After reading what guys on the FJR site go through to get particular routes loaded onto their GPS units I just decided to get lost once in awhile, it's a LOT less aggravating to me than struggling with BS software that fights you at every step.
