- make sure "Recording Track" and "Jump to the current position..."
  in GPS layer properties dialog are ticked.
- make sure the GPS layer is above all other maps layers.
  (or just turn off all map layers for testing)
- Data collected are stored in a new track in GPS layer's
  Realtime Tracking folder. Check if they are there.

For testing purposes, I would suggest to collect the NMEA data on driving
and then feed data to viking on your desk.

The way I use while developing the codes is:

In the car:
 $ gpsd /dev/ttyUSB0
 $ (echo "r"; read) | nc localhost 2947 > data.nmea

At home:
 - (do _not_ run gpsd)
 - comment out the first line of the file
   "#GPSD,R=1"
 $ gpsfake data.nmea
 - Click on "start realtime tracking"


gpsfake will, default, repeat over and over again the same track.

Hope that help.
