What is a NMEA compatible GPS receiver – how do I know if have one?
NMEA is a standard protocol for sending information from a GPS receiver to other devices. Most (i.e. we don’t know of any that don’t) GPS receivers can use this protocol. Look in the manual for your GPS receiver to find out how to tell it to switch it into this mode. Many of the Garmin GPS receivers have been tested with LocateIII. Please let us know which ones you have tested.
