[dgoeken] sent in his Magellan 3100 hack. The device runs Windows CE 5.0, and mounts as a standard flash drive. Since everything is easily accessible, it’s just a matter of replacing and modifying the appropriate files. According to the GpsPassion message board, some are finding his guide useful for other models of Magellan GPS. So far he’s added a file manager, media player and upgraded the Points of Interest file. The site is slightly bandwidth challenged, so I’ve mirrored his hack process here.
