I am also looking forward to the next run...
I recently went out and installed a Holux SuperMouse NMEA GPS receiver and attached it to my Rio.
GPSapp works very well.... however, I am having a problem with empgps.
It displays the number of satellites and a 3D fix, but it does not display Lat, Long, Time, Date, Speed, or Heading.
All of the values remain at 0 even when my car is moving.
Do you think that the NMEA sentances coming out of my receiver are not being parsed correctly by empgps?
I can upload a few as an example if it would help the troubleshooting process.
