Bushnell GPS info

 

Has anyone successfully figured out the formats used on many of the handheld Bushnell units such as the 200, 200CR, 300 or 400 series?

I recently got a 200CR for $50 (refurb) and on the device, it sets each waypoint as its own WPT file. I tried to download one of their free maps online but it says no download file so thats kind of a pain to deal with.

I too whould like to load POI into this.
ALSO,, I'm looking for a "cradle" mount. I found a few on-line, and they were all sold out, and no longer available. My main use of this is the weather feature.
