I have problems with using cracked protocols in GPSMan: I am a
professor at a public university and so I cannot infringe
copyrights... On the other hand I'm free to give information
on how GPSMan is implemented and how it can be extended.

Ok. I suppose that TomToms also support the NMEA protocol but I
don't know if they have something similar to the proprietary
extensions used by Garmin or Magellan. If there is a description
of this it may be an alternative.
