Question

its a thing where u connect your mp3 and can listen it in your car.

Answer 1

I bought a device called "trip tunes" through ford. It has a headphone jack, a cable, and plugs into the antenna port on the back of your radio. Works great, and will fit most vehicles (not just ford). Cost about $60.

Is that what you're looking for?
