Great. $GPRMC is all it *needs*, the tripmate init is purely optional.

Try feeding a RMC sentence directly from your terminal program. Here's one I have handy:

$GPRMC,135356,A,4203.6470,N,07123.4961,W,61.308,294.3,180302,15.8,W*78

This is from a tripmate but a Trimble should be similar. (Perhaps my error detection code is too strict though. If this sentence works and yours doesn't, please send me one.)

Was the player fully exited at that time? I am having serial problems but only when the player is mucking with the port.

picker, along with preinit, would be the way to go for now to start it in the car. You can't simply run it at background at init time until I have the serial problems fixed.

I'll come up with something for picker.

Cheers,

Rex.
