We purchased our Explorist GC from REI since we know REI has a full satisfaction guarantee (refund policy). Other than a few glitches, it seems to be a good unit -- unfortunately, some of the glitches make finding a geocache more difficult (track featuring only working occasionally). If they don't get the firmware out soon, I think we will invoke our return privileges. I understand patience, but I thought Magellan had released there would be an update out by the end of May.
