Okay, so I have an old FM transmitter that I want to use in my car, so I can play tunes off my phone. Unfortunately, the transmitter doesn’t have Bluetooth capability AND has a 3.5 audio jack for whatever device your wanting to play music from....but I have an iPhone and honestly don’t want to pay for another adaptor because I just lose them . My question is....if I take a pair of my iPhone headphones, cut the jack off those..would it be possible to splice it onto the transmitter where the 3.5 audio jack is? Need to know before I start cutting wires
