Toyota Vehicles with a Factory JBL Amplifier & Stinger Radio Kit: Audio Intermittent at Statup

If you encounter a situation where there is no audio output, and you find that toggling the key restores the audio, follow the steps outlined below to resolve this issue.

1. Identify the Blue/White wire within the Radio Harness connector originating from the PAC module. (Refer to Figure A)
2. Carefully remove the Tesa tape to provide additional working space.
3. Cut the Blue/White wire, leaving approximately four inches of wire extending from the Radio Harness connector.
4. Insulate and disregard the wire segment leading toward the radio (indicated by an X mark in Figure A).
5. Using a scrap piece of primary wire, extend the Blue/White wire by approximately eight inches (indicated by a check mark in Figure A).
6. Locate the red and black wires labeled Aftermarket Camera Power. (Refer to Figure B)
7. Connect the extended wire to the red wire. The red wire is equipped with a female bullet connector. You may either attach a male bullet connector to your scrap wire and connect it, or remove the bullet connector and hardwire the wires together.
8. Power on the radio and verify proper functionality.
