IMPORTANT: If you need model-specific information to complete these steps, refer to your device's manual. Manuals are posted on your model support page.

  1. If the car stereo has a detachable faceplate, clean the metal contacts with a cotton swab lightly dipped, not saturated, with rubbing alcohol.

    WARNING! There's a risk of personal injury. For safety, before cleaning the connectors, turn off the engine and remove the key from the ignition switch.
