Cheap/Mod your own GPS

I have done that and it WORKS great!
Do you know if you can do the same thing with an Earthmate?
I know it is not NMEA. I got the GST-1 to convert the data to NMEA format.
I just havn't been able to modify it to work standalone like the Tripmate.
I would imagine it would be a similar modification.
Have you ever heard of anybody using an Earthmate with the TinyTrack?
Yes. I got the GST-1 to work with the computer, but it sends initialisation codes to activate the GPS. I can't get it to work standalone (without the computer)
