I have a new-to-me Dynavin N7 Pro wince HU that came with a licensed copy of Igo Primo. Despite the unit having a TMC receiver there's no TMC displayed with Primo. I'm in the UK, where TMC is carried on Classic FM on 100.9 MHz.
This is the TMC section of the Primo sys.txt
internal_tmc_name="royaltek"
source="royaltek"
port="COM,3"
baud="38400"
I know the unit definitely has a receiver because TMC does work with igo 8. ...
