You need a stereo cable (male to male 2 EP cable) this will connect to your Sony player on one end and the other end should connect to the Car Audio ( you did not specify the CAR audio make and model) hence i am assuming that you might have a stereo input connector.

If its not there and you have a cassette player in your car audio then you have to use a car cassette adapter

there will be a small pinhole on the back of the device and push a pin or something small in that and it will reset it

Question edited for clarity. Question moved from Cars and Trucks. Remove the batteries to reset it and also stop it..

The motor might be broken and is not working and will have to be replaced in your walkman.

ouke its work . but why my mp3 doesnt on ?

Try removing any covers that you can without breaking anything, then fill a container with uncooked rice and push the player into the rice and cover the container. Leave it like this for a week or so.

@Gikanne: it's not working..

Either the left headphone is shot or the headphone jack is messed up. Try a different set of head phones if its same result see about replacing the jack.
