John, You (and Stefan) are probably right - making an OSM to TomTom data format converter would probably be more sensible and take less effort.
I had hoped that the TomTom code would have had a standard graphics library included so it would be easy to port an existing OSM based router to it, but it will take quite a bit of effort to port a suitable library to it. The difference is, I can see a way through building an application on the device (which could include GPX track logging etc.), but I don't really know where to start decoding a proprietary data format! Maybe someone else knows how to go about de-coding the data format? Regards Graham.
