I have be use this unit for about a week now . in a word , it be awesome . it act as a flash drive when connect via the include usb cable . you can access all the file store on the unit in this way . apparently , most gp unit only have serial connection and must use proprietary software to upload file . -lrb- I be very happy that I do not have to deal with that on this unit . -rrb- also , the geocach point feature be very nice . I simply use the include software to convert my . gpx file to the . g use by the unit . this let you carry the coordinate , person who place the cache , last find , hint , etc info with you . I think the only thing miss be the `` description '' field . however , I do not know if any gp unit will show that field . in most case , you do not need that field anyway . I have use the unit to log about 20 cache find so far . in any case , I highly recommend this unit .
