Had a few problems with the car connector , the pins go weak and do not give a good enough connection , will probably need a new one , but to save hassle when you take car in take your MP3 player and cable in and show them and make sure you tell them that you have tried 2 different players and 2 different cables , and also checked these in another car so the only sensible thing would be the plug , try just putting a slight bit of sideways pressure on it sometimes this gets it to work and can be shown to prove your point .
