yeah I'm keen too, to find out how to change it (118 to 120)..

I've all so notice that the music and static ratio is pretty bad too, like the volume of the music that is being sent to the transmitter is quite low for example you wound be listening to it in the car you wound have the volume turned up high, higher than nominal..but if you were listening to nominal radio the music is louder but you don't need to turn up the volume as high and theirs next to no static in the back ground.

I hope that made sense..
