yea, i think the earthmate is dead. I friend let me use it, a battery leaked acid onto the board before he gave it to me, and i can't even get it to work on pc but i don't really have any software, just some freeware Eartha2NMEA.exe. what i really need to get my hands on is a voltage meter, found a nice website that details a few things to test to make sure the unit works. I think i should just go find a NMEA gps receiver first.
