Discussion group for the Garmin GPSMAP 60C and 60CS color GPS receivers. There is also a group for the Garmin 76C/CS that you can subscribe to here: http://groups.yahoo.com/group/Garmin_GPSmap_76C The 60C/CS are almost identical to the 76C/CS except they're different form factors, the 76C/CS has twice the memory and it floats.
