I've been doing the way points on the desk top, then downloading that to the scandisc (probably take two) and checking to make sure it works on the GPS. Then copies are downloaded to my laptop then to the netbook which I'll be taking. TAT maps and roll charts will be taken as a backup, since anything electrical can fail.
The TAT route has be divided into smaller routes. Two separate routes for each state. The earlier 550 wouldn't take a full state route and waypoints. The newer version (two old ones crapped out) took all of Colorado w/o any complication. I don't know kind of weird the way it worked.
BMW independent shops and dealers have been added, you never can tell and the MOA Anonymous Book will be taken.
I'm not very good w/ maps and directions the GPS will help keep me on the right track.
