I’ve read people saying that phone buttons does nothing, then people say that you need to pair your phone first to have any function to the phone button. I look up how to pair a phone and it says that you need to press the phone button. I’m at a loss here. The aux and the USB port do not work either, all of this has been the same since I bought the car a year ago with only 54k miles. I just want to be able to connect my phone to the stereo to play music instead of cutting the quality by using a FM transmitter. Help would be greatly appreciated!
