mp3 in car

i have a car stereo with only radio and tape deck no cd player. dont want to change it because radio is great quality.and dont really have the money.
have been playing cds using a portable cd player, which wasnt very stable and a farce, and tape extension kit, thingy.

i am getting a zen touch for xmas. is there another way of connecting this in the car.
also is there a holder for the zen to put on the dash.

From Bristol,

You can buy a tape that plugs into your mp3. Check out the Argos catalogue.

From Glasgow,

yes, buy a wirless mp3 to radio device. Ipod have a version of this called an 'itrip' but this will only work with ipods. other brands are now available for most mp3 players.

to use it is simple, plug it into the headphone socket. Turn your radio to a frequency with no sound, just static noise, and then turn on the device and play your music. Your music will come through the radio like a normal station.
hope that helps
