ar eyou getting any LED on on top of the bluetooth adaptor. When you turn the ignition on the adaptor flashes orange indicating its searching for devices. If you have pairded your phone it will turn to solid red. If not it should come up with a message on you phone if you are also searching for devices. You will need to enter the pairing code in.
