I was talking to Jack Conrad the other day about problems I had with MS Streets and Trips and also Delorme SA2006.
He mentioned that he had links for different data files for Delorme so I checked on the internet and found this:http://www.discoveryowners.com/cginfolinks.htm
These are files for Delorme, MS Streets, Co-Pilot, Mapsource, Magellan, TOMTOM 0V2, and Way Points.
I don't know if they all work, but am working on some of them to get them going in my two GPS programs.
I hope they will help others, especially after reading the recent post on a low clearance in San Diego.
