Radio Transmitter

It works like this: plug it in the earphone jack of your what-so-ever sound player, it transmit the sound to your car stereo via FM signal. You just use your car radio and tune in for the transmitter's freq.

It costed approx. 300RMB when I saw it in SZ last year. Now you can find one under HK$100 at MK. I get one, and use it with my shuffle when I drive to and from work.

It works as expected.
