We are using a Garmin GPSmap76. After 3 years of printing cache descriptions today I was able to download for the first time. Why I haven't figures it out before is beyond me. But, naturally this doesn't tell us anything about the cache. Parking, size etc. A friend told me to get an inexpensive palm pilot but I have no clue what kind, what I wold need if this is the only thing I would be using it for. HELP PLEASE?
