Hello

According NIMEA specification:

Course.SpeedN is speed in knots;
Course.Speed is speed in km/h

Thanks for the info.  I tested the demo project with my GPS device, but the speed is always reporting 0 when I am moving.  I tested the same GPS device in Mappoint, and I get a reliable speed.

I took a look a the GPS sentences from the device and I do see speed indicated in the GPRMC sentence:

$GPRMC,132843.000,A,3754.7776,N,12220.7196,W,0.14,56.74,040412,,,A*4B

Hello

GPRMC returns speed in knots only.  Please check SpeedN value in event (demo shows only Speed in km/h) .

For speed in km/h your GPS device should provide GPVTG sequence.
