All of the trip routes described in the book contain the GPS waypoints to aid in your navigation, we have made them available for download here to save you reentering them. Below are a couple of suggestions if you need help getting the waypoints into your GPS.

We use EasyGPS for linking our Garmin GPS to our Windows PC. EasyGPS is available for download here.

If you use another OS then you might want to check out GPSBabel which claims to work on MACs Linux etc. GPSBabel is available for download here.
