I have a Magellan Explorist that was great for a year and a half then while out caching it quit picking up a signal. Everything works except that it won't pick up the satellites! Updated it - still doesn't work. Just bought a Garmin Oregon 450 and love the touchscreen. The salesman at Cabellas trold me that Magellan has been having a lot of trouble with their equipment so I didn't buy another but I loved it.
