That'd be the 'newer' Earthmate with the Sirfstar that does NMEA and can be 
used with Bluetooth or USB with the kits.


The Earthmate unit uses the SirfstarIIeLP.  SirF doesn't say on their site 
what NMEA version that is though.  Some other sites say the Delorme is NMEA 
2.5.  So as far as I know your D7 shouldn't need the NMEA 3.0 firmware 
update to use this unit.

As far as I know it should be.

PIN 2 - Input From D7
PIN 3 - Output to D7
Pin 5 - Shield Ground

The transmit from the D7 shouldn't be needed because the Earthmate doesn't 
have a screen and doesn't support waypoint management.

Make sure your D7 is set up properly too, for the Earthmate it should be 
4800 baud if I recall.
