Yes I am using the gps with my delorme to track location, not transfering maps. Sorry for the confusion
ex500 settings are nmea apa,xte,gsa ???
Delorme : Magellan w/wpt, magellan o/wpt, generic nmea, and other brands garmin,etc....
I have picked both magellans and generic nmea, and all the settings on the ex500. And its state "can't open specified USB port" . Usually I get that when a setting is wrong. Port works fine, system sees gps, delorme works on all the other gps's I have owned.
Or do I just put the unit in power only mode. The instructions with the unit is very vague. And delorme is the same.
I just might be out of luck.
Thanks,
Matt
