Firstly, you need to use a GPS program to download the GPS files on your computer. I suggest you use EasyGPS, because it is compatible will all major GPS models: Garmin, eTrex, Colorado, Dakota, GPSMAP, Edge, Montana, Oregon, Rino. Once you transfer the maps on your PC using the EasyGPS program, click the Print button (
) to print your files. For further information, press the F1 key to open the user guide.
