I want to pair my IPhone to my roadster.

Bluetooth that shit or turn the key three times in the car and look at ur miles and a code should pop up If not buy a aux cord cassette tape instead - nick guru of cats

You'll have to remove the inner panels in the back of the car on the driver side to access the Bluetooth module, it should be a rectangular sliver box. It it should have a sticker on it, and either a P/N or Passocde number that you can use to pair your phone.
