Hi Peter,

I have to make a software that is running some operations on GPS data and then returns the coordinates corrected to TomTom for navigation.

What the software should do is:
1. detect the GPS from a bluetooth device
2. correct the GPS data
3. TomTom navigation with GPS data corrected

How can achieve the point 3, ie pass to the TomTom the custom GPS data, with InTheHand.TomTom? Should I use the property ExternalGPSInput?
And if so, in what way?
Thanks for any response,

Carlo 

ExternalGPSInput returns a Stream object. You'll need to write your amended NMEA ASCII data to this stream using a StreamWriter or writing directly from a byte[ buffer depending on how you perform the modifications to the data.
