First time I hooked up a GPS to my Tiny Trak it didn't work. I was using 
a Garmin handheld. On investigation found it was not outputting correct 
mode. Using the GPS internal menu  I switched to the correct NMEA output 
string and it worked fine.
I may be off beam but could be worth checking the GPS is set to output 
the correct string? I guess you have probably done that though?
