I have the Sport and have changed out the head unit to a JVC. I bought Metra controls to be able to control the radio from the steering wheel. Everything works fine but I don't want to use the Mute button as a Mute for the Radio. I want to change the resistor on the Mute button to actually call up the bluetooth for the Radio when the Mute button is depressed. Does anyone know the resistor size I would need to change the Mute button to act as a Bluetooth button?
