GPS Graveyard...

Garmin GPS III+ mounted on Land Rover dash.

What happens to old GPS units?  Those ancient direct-line-of-sight GPS receivers that would take minutes to acquire the satellites and could only hold 1.44meg of internal storage which was used for waypoints, tracklogs, routes and basemaps.

My old GPS is currently abandoned in a cupboard drawer waiting for a need to be turned on.  It's a Garmin III+ with the world basemap along with limited coverage of Africa.  It uses a serial cable to download and upload the data to a computer (which PC has a serial connector now?).
