GPS Tuner 3.5 for PocketPC

Lost with a PocketPC?  Want to use custom maps for GPS?  GPS Tuner 3.5 is a PocketPC tool that allows measurement, mapping, and geocaching.  It uses an averaging technique to record waypoints, it's GPX compatible, and handles NMEA logging and playback in real time.  It also comes with Digital Compass, which is pretty what it sounds like it is.  As far as custom maps, you can use GIF, JPG, PNG or BMP files, and the people at GPS Tuner offer a sharing forum for custom maps from around the world.  The archive is pretty small right now, but if you're planning a hike through Csopak, this just may be the Pocket PC proggy for you.
