If you got mp3 player, you plug the fm modulator into the mp3 player audio plug. On the FM modulator, and then you on your car player audio and you can listen to it.

I dont suggest it as there are interruption noise. A line in (No Cost) is a better solution, no interruption or so.

FM Modulator can get at the price of RM50. I've got an extra one if you want, my previous one before I know anything about LINE IN.

Tell me if you want

thank you
