Hi folks,
I think I found a fly in the ointment.  The PC side of FSX2Android appears to be outputting the FSX aircraft heading instead of the track.  I have sent a message to the developer.  GPS can only calculate track, and that is what apps using the devices' GPS would assume is being provided.  I'll let you know if I hear back from the developer, but maybe if the developer heard from more users about correcting the output to track instead of heading...
 
Thanks,
Jim
