Navionics NAV-MSD/1XG Gold All USA and Northern Bahamas on SD/microSD Card

I purchased it in August, 2011, but haven't been able to use it because the SD card reader in my Humminbird chartplotter doesn't work. I am asking $80, shipping included.

The card seems to be generally compatible with Humminbird and Lowrance chart plotters; please consult Navionic's web site [http://www.navionics.com/en/compatibility] for specifics.
