Earthmate GPS
OziExplorer cannot work directly with the Earthmate GPS but there is a utility which does allow it to work with OziExplorers moving map mode.
The URL for the software is:
http://www.ozemail.com.au/~tooraj/eartha2nmea.htm
Please note that I do not control this link and therefore its availability.
Download this utility and start it running an communicating with the GPS and then start the moving map mode of OziExplorer.
