Dell Axim x51v in Wherigo Hardware Posted February 23, 2010 I want to be able to geocache with my Dell Axim x51v. What do I need to purchase as far as a GPS unit for it? Programs? Maps? Please help!! -Mooka520 I have a Dell Axim X51 with WM6. I use a GlobalSat BT-359. This is a bluetooth GPS with SiRF III chipset. Very nice and reasonable on E-Bay. For software there are many freeware progs to choose from: BasicGPS is a good GeoCache Prog (no maps, but will display cache info..made for geocaching) OpenMobile Maps is OK but not a GeoCache prog (maps only) NaviComputer is OK and will let you work with GPX files (has the ability to download and display maps). hope this helps.
