Literally took two seconds to hook it up and it was working. This thing is AMAZING. We own an older vehicle and dont have any bluetooth or Aux options for us to use our phone to listen to music through the car speakers. I plugged this in and turned it to a radio station frequency that I chose and instantly music was playing through my truck speakers from my phone :) I couldnt be more pleased and my kids are over the moon because they can now listen to their movies ect right through the car speakers. This is one amazing purchase.
