Not really, it should work for anyone. This one is set to free regional.
I'm using Global firmware by the way and the standard FM transmitter is the same.

Try enable your FM Transmitter and make it get a lock onto one channel.

Then install FM-faker from Repository Extra-Devel. Make sure your FM Faker is the latest. I have FMBoost installed, and FMTX widget. So try those too, installed them and do it again from the start.

This is why the back up file of the fmtxd will come in handy if things go wrong!

If it keep saying "Unable to use ...blah" then it's either you've installed FM-Faker before this process.
