4.2 Reversing Camera Installation Method

The reversing camera is typically installed at the rear of the car. Follow these steps for proper connection:

Image: Reversing camera wiring diagram.

1. Identify Wiring: Locate the reverse control line (pink wire) on the unit's power line. Connect this line to the 12V positive pole of the reverse lamp. The screen will turn blue when reverse gear is engaged.
2. Connect Video Input: Find the CAM video input interface at the back of the unit. Connect the video cable from the camera to this interface.
3. Camera Power: The camera typically has two sockets. The red socket connects to the camera's power cable. The yellow socket is for the video cable. The red wire of the camera's power cable and the red wire of the video cable should be twisted together and connected to the positive pole of the reverse lamp. The black wire of the camera's power cable is usually not used.

Important: If the reversing camera is not installed, do not connect the REVERSE/BACK cable to any location. Leave it unconnected. Incorrect connection can cause the unit to display improperly or automatically enter reverse mode, leading to malfunction. If this occurs, disconnect the REVERSE/BACK line immediately to restore normal operation.

6. Troubleshooting

This section addresses common issues and provides solutions. If you encounter a problem not listed here or if the suggested solutions do not resolve the issue, please consult the official user manual PDF or contact customer support.

6.1 Cannot Boot Normally

1. Wiring Check: Ensure the yellow (B+), red (ACC), and black (GND) wires are correctly connected. Yellow to positive, red to key control, black to negative. Incorrect or incomplete connections will prevent booting.
2. Original Car Wiring: Do not connect the unit's wiring directly to the original car's wiring if the colors do not match, as original car wiring colors are not standard. This can cause damage.
3. Original Car Plug: The original car plug cannot be directly plugged into the new unit. Even if it fits, it may not function or could cause damage.
4. Fuse Check: If the 3 wires are connected correctly but it doesn't boot, check the fuse on the yellow line. If the fuse is intact, twist the yellow and red wires together, turn the key, and press the unit's power button.
5. Persistent Fuse Blowing: If the fuse blows every time it's replaced, it indicates a short circuit in the unit's protection circuit. The unit may require professional repair.
6. Final Confirmation: If all checks fail, connect the yellow and red wires to a 12V battery (positive) and the black wire to negative. If it boots, the issue is with your car's wiring. If it doesn't boot, the unit is faulty.

6.2 Automatic Shut-down

1. Cable Connection Error: If the blue (automatic antenna power supply) cable is connected to the unit's power cable, automatic shutdown will occur. Follow the correct wiring method.
2. Unstable Voltage: Test with a stable 12V-5A power supply. If the unit still shuts down, it is faulty. If it operates normally, replace your car's power supply.

6.3 Audio Issues (Noise, No Sound)

1. Noise: If the original speaker power is too low, noise may occur at high volumes. Replace speakers or reduce volume.
2. Grounded Speaker Cable: If a speaker cable is grounded, connect the iron speaker cable directly to the unit's speaker cable.
3. No Sound After Installation: The unit is tested before shipment. If there's no sound, it's usually a wiring error or a short-circuited original car speaker wire.
   • Check for short circuits in speaker cables and reconnect if necessary.
   • Verify the number of speaker cables. If your original car has only 2 speaker cables and the unit requires 4, you may need to re-route the original car lines. One speaker should lead to 2 speaker wires, meaning 2 speakers need 4 available cables.
4. No Sound After A While: Disconnect all speaker cables from the unit. Connect an external speaker to the gray and purple lines of the unit's tail line. If there is sound, the car's speaker line is short-circuited or the speaker is damaged. If there is no sound, the unit is broken.

6.4 Remote Control Not Working

Test the remote control by pointing it at your phone camera and pressing a button. If the phone camera shows a light, the remote control has power. If not, replace the battery.

6.5 Settings Not Saved (No Memory)

1. The yellow and red lines are connected together (yellow to positive, red to key control).
2. The yellow and red lines are reversed (just swap positions).

6.6 Bluetooth Not Working

Turn on the unit, search for its Bluetooth name on your mobile phone, and connect. Once connected, you can answer calls or play music via Bluetooth.

6.7 Product Emits Smoke

Replace the FUSE. If the problem persists, the internal circuit is burned. After-sales service is required.

6.8 Reversing Camera Not Displaying

1. Wiring: Check for incorrect or missing wiring as described in section 4.2.
2. Camera Fault: If the camera's lamp (when properly wired) does not light up, the camera is broken and needs replacement.

6.9 USB Devices Cannot Be Played

Format the USB flash drive to FAT32. Re-download one or two songs and try again. If it still doesn't work, replace the USB flash drive.

6.10 FM Does Not Receive Radio Stations

1. The antenna plug is not fully inserted, or the antenna/line is disconnected.
2. Search for stations using the AS button for automatic search, or the previous/next buttons.
3. If the above doesn't resolve it, unplug the antenna plug and insert a screwdriver or metal strip in its place as a temporary antenna.

7. Maintenance

Regular cleaning of the screen and buttons with a soft, dry cloth is recommended. Avoid using harsh chemicals or abrasive materials that could damage the unit's surface.
