MI VHNTR, is right. Take a look at MapTech. I have seen a number of recommendations for their products. I have never used their product, But last night I checked the USGS, DeLorme, and MapTech webpages. I noted that MapTech is going to release a free upgrade to their software this year. Their upgrade address the USB drivers on the Garmin 60C, 76C series gps units.
One up for Map Tech. :toast:
