Connection Steps:

1. Locate the reverse control line (pink wire) on the unit's power line. Connect this line to a +12V positive source. The screen will turn blue when reverse is engaged.
2. Find the CAM video input interface at the back of the unit.
3. Connect the camera's red power plug to the positive and negative poles of the tail light. The yellow video cable from the camera connects to the CAM video input interface on the unit. The red wire from the video cable connects to the reverse control line.
4. If the reversing camera is not installed, do not connect the REVERSE/BACK cable. Leave it unconnected to prevent incorrect display or automatic entry into reverse mode.

2.4 CANBUS Connection

The CANBUS connection varies depending on whether your car model is high-end or low-end. Refer to the diagram below for correct connection.

Figure 2.4: CANBUS connection for high-end (disconnect CANBUS) and low-end (connect CANBUS) models.

For High-End Model Cars: Disconnect the CANBUS box and black buckle.

For Low-End Model Cars: Connect the CANBUS box and black buckle.

Attention: If the CANBUS box and black buckle are connected simultaneously when not needed, it may cause the radio to fail to shut down after the car is turned off.

4. Troubleshooting

4.1 Common Problems and Solutions

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 insufficient connections will prevent booting.
2. Car Line Compatibility: The original car line and unit wiring colors may not match standard. Connecting incorrectly can damage the unit.
3. Original Car Plug: Do not plug the original car plug directly into the new unit if it's not designed for it, as it may not work or burn out.
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 on the key, and press the unit's power button.
5. Persistent Fuse Burning: If the fuse burns every time it's replaced, the unit's protection circuit may be short-circuited. Seek professional repair. To confirm, connect the yellow and red wires to a 12V battery (positive) and black to negative. If it boots, the car's wiring is problematic; otherwise, the unit is faulty.

2) Automatic shut-down

1. Cable Error: If the blue cable (automatic antenna power supply) is connected to the unit's power cable, it will automatically shut down. Follow the correct wiring method.
2. Unstable Voltage: Test with a stable 12V-5A power supply. If it still shuts down, the unit is faulty. If it doesn't, replace your power supply.

3) There is noise

1. Speaker Power: If the original speaker power is too low, increasing the volume will cause noise. Avoid excessively high volumes.
2. Grounded Speaker Cable: If a speaker cable is grounded, connect it directly to the unit's speaker cable.

4) Remote control cannot be used

Test Method: Use your phone camera to check the remote control's IR emitter. If the light doesn't illuminate when a button is pressed, replace the battery. If it lights up, the remote control is functional.

5) Settings can not be saved (no memory)

1. Wiring: The yellow and red lines are connected together (separate yellow to positive, red to key control).
2. Reversed Wires: Yellow and red wires are reversed. Change their positions.

6) Bluetooth not working

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

7) The product emits smoke

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

8) The sound cannot be adjusted

1. Reset/Power Cycle: Reset the unit or unplug and replug the power cord.
2. Volume Knob: If the volume knob is broken, it needs to be replaced.

9) Reversing camera does not display

1. Wiring Issues: Check for incorrect or missing wiring. Refer to section 2.3 for camera connection method.
2. Faulty Camera: If the camera is properly wired but the lamp doesn't light up, the camera is broken and needs replacement.

10) USB devices cannot be played

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

11) FM does not receive the radio station

1. Antenna Connection: Ensure the antenna plug is fully inserted and the antenna line is not disconnected.
2. Station Search: Use the 'AS' button to automatically search for stations. If issues persist, unplug the antenna and try inserting a screwdriver or metal strip into the antenna port as a temporary test.

12) There is no sound right after installation

If there is no sound immediately after installation, it's usually a wiring error or a short-circuited original car speaker wire. Check the following:

1. Speaker Cable Short Circuit: Verify that speaker cables are not short-circuited or improperly connected. Reconnect if necessary.
2. Speaker Cable Count: If your original car has only 2 speaker cables, but the unit requires 4, you may need to re-route the original car line. Each speaker needs 2 wires.

13) There is no sound after a while

Disconnect all speaker cables from the unit (do not remove them). Connect an external speaker to the gray and purple wires of the unit's tail line. Test with any group (e.g., green). 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 faulty.
