To activate Amigo USA/Canada TMC you must have the proper sys.txt for your GPS. Examples of TMC sys.txt options are listed in the data.gro/config folder. Plus (+)

I don't have a TMC receiver, however if I did then I can see where this would be very handy. I can assume it only works in Amigo though... shame it doesn't work in igo8 or Primo.

Only for Amigo...
