Can I hook an AUX cable to my stock car stereo – Ford Ranger?
I have a 2002 Ford Ranger xlt with the mach mp3 stereo. I was wondering if I could run a 1/8″standard headphone sized AUX cable from the back of it so I could hook my zune mp3 player up to it. I am getting tired of carrying CDs around, there is no tape deck for a tape adapter, and the FM tuners just never work that well. Is this possible without replacing the whole stereo?
You can try one of these,it runs through your antenna so it’s not wireless like an fm transmitter.
