| Symptom | Likely Cause | Fix | | :--- | :--- | :--- | | No memory (presets lost) | Yellow wire has no 12V constant | Check fuse or connection to battery. | | Radio turns off with key (no ACC delay) | Red wire connected to accessory | Normal behavior. If you want delay (turn off after door opens), rewire red to a different ignition source. | | Screen dims during the day | Orange/white wire connected backwards | Disconnect orange/white if you don’t want auto-dim. | | Static or no sound from one speaker | Speaker wire polarity reversed (+ and - swapped) | Swap the two wires on that speaker. | | Amplifier stays on after car off | Blue/white connected to constant 12V | Move blue/white to the red (ignition) wire or radio’s remote output. | | Parking brake bypass not working | Light green wire not properly sequenced | Requires "on-off-on" sequence. Use a PAC TR-7 or similar bypass module. |
| Wire/Jack Color | Function | Use Case | | :--- | :--- | :--- | | | Aux Audio Right Input | For connecting an external MP3 player or game console. | | White RCA | Aux Audio Left Input | | | Yellow RCA | Composite Video Input (AUX) | Used for backup camera or external video source. | | Yellow/Black (wire) | Rear View Camera (Reverse) | Connects to the violet/white reverse trigger wire. This activates the camera image. | | Violet/White | Reverse Gear Signal Input | Connects to the positive wire of your reverse light. Tells the radio you are in reverse. | | Green/Yellow (thin wire) | Steering Wheel Remote Control Input (SWC) | Connects to an aftermarket steering wheel interface (e.g., Axxess, Metra, PAC). | | Black/Thin | SWC Ground | Pairs with the SWC input above. | Pioneer Avh X3600bhs Wiring Harness Diagram
