Anyone have any experience getting waypoints out of a garmin GPS to a PC? I just got a GPS 76 handheld. I'd like to offload my waypoints from the old 48 to the new one. Although Garmin provides a PC cable it's an old 9 pin and everything is USB these days, but they'll sell me an adapter cable for $60!!!! Before I waste money on an adapter I'd like to know if the download upload thing works or if the new software will even work on the old ones.
