USAPhotoMaps is rock. I've used it for the last couple years now.

Here's a great freebie to go along with it: EasyGPS . Do yourself a favor & grab it now. In addition, I have State files for it with tons of landmarks, etc. PM & I'll make them available for you.

Degree/Minute/Second Converter is a must have in any GPS toolbox. It converts to/from different formats which REALLY comes in handy when your unit & any programs you like to use together displays in disparate formats.

I've got some other programs for astronomy like Sunrise/Sunset calculators etc.. Just call me Mr. Utility. I'll be happy to answer any questions, search, or try to provide utilities for your use. I don't program anymore but if I ever need anything, I'll download 6 or 7 5-STAR programs, install them all, & throw away all but 1 or 2. Ease of use, small memory footprint, practical, nice standard interface, etc are all requirements I adhere to. Free is good too ;P

Have fun!
