Summary: I had no problem getting this device running and downloading full cache info from[...]. As for pocket queries, it was easier to open the GPS as a hard drive and simply drag the unzipped query into the geocache folder as opposed to messing around with the recommended programs. The screen is hard to see in the sunlight and the map zoom is awkward and a stuggle at best. The big BUT. The joystick/navigation nub ripped off after only three months rendering the device useless.
