I just received it this past week and am not familure with all of the PN-20's functions. It appears to have most of the functionally of some of the higher end Garvin unit. I went with the PN-20 as I already have several Delorme products. Most of the reviews I saw for the PN-20 were pretty good. It was a toss up between the PN-20 and the Garvin 60csx. I thought the Garvin Colorado looked good until I started reading about some of the problems new users were having with this unit. I sure Garvin will get the bugs worked out, but I didn't want to get frustrated while they were working on the problems.
"How about its Geocaching functions? Are they similar to what Garmin offers, like with the little treasure chest symbols for geocaches, and the "find next closest cache" function?
