Excuse me in advance, but it's still not 100% clear to me. I don't know the device at all so I am not sure what you mean exactly.
We (Filesupload100 and myself) THINK you mean TMC, but we can be wrong in the end.
Thus can you clear up when I make this note?
TMC and "FM transmitter" - watch me use the word "transmitter" - are not the same and are not related to each other.
A "FM Transmitter" function on the device lets the announcements/directions/warnings of the GPS, that is the sound, come out of the car stereo speakers.
"FM receiver" could mean a radio, but that does not mean capable of the reception of TMC messages. Therefor you need a TMC module (receiver).
When you mean TMC, then Filesupload100 asked the right questions.
