For something a bit more "marine-y", download a copy of OpenCPN and get the NOAA charts. This has a Garmin mode for sending routes/tracks between the two and I think you'd find it more useful than the easygps which is I think a bit more generic.
I have a usb cable to connect,my plan was use the little garmin to transfer the info. onto my laptop for easier viewing,thanks i'll check into opencpn
