Voice dial comes up if I touch the audio cord. HELP!!!

I plug my phone into my cars auxiliary jack to listen to music while I drive. If I touch the cord the tiniest bit, it pauses the song and opens up voice dialing. Does anyone know how to stop this? It's so annoying. I've never used voice dialing and I don't plan on starting now. Please help

Hopefully it's a defective cord. Replace it and see if the problem goes away. If it's not the cord, it may be the socket on either the phone or your car's audio input. Neither socket will be easy or cheap to replace.
