Another option is the free download "Chart Navigator" from MapTech.

Thanks Doug, I'll have a look at it.


It may not have GPS input among it's "working features." I had an
older version on another computer that was rather cranky. The new
version won't work with the GPS hockey puck I have, which I attributed
to 1- cheapo off-brand GPS and 2- my lack of computer expertise. It
does have what look like functioning menu options for GPS input.
