GPS Units With Built In Software For Paperless Catching in GPS technology and devices Posted April 2, 2008 I just recently went paperless - considered the Colorado but got a 60CSx and a used Palm instead. How well do the dongle-equipped PDAs work for caching? I doubt they're as rugged of course, but what about software? The car GPS's are nice, but lack the abitlity (at least mine does) to do the bits needed to find a cache. I thought about the PDA/gps route but was afraid I'd be swimming upstream alone trying to get it to work for caching.
