I use a program called gypsy with my Garmin GPS and Mac laptop. I t allows
me to download maps from a variety of servers that are the USGS 7.5 x 7.5
minute maps. You can upload data points from the GPS and download way
points from the program to the GPS. By placing the cursor of the computer
on a spot of the down loaded maps, you can read the exact coordinates in a
variety of formats. By then clicking, you can create a waypoint that can be
downloaded to your GPS. Cost $50 for the program and $10 for the cable.
With the laptop, you can hook both the computer and the GPS to your boat
battery for maximal use.
