Troubleshooting

1. Why can't the car radio turn on?

• Check Voltage: Ensure the car radio receives 12V.
• Power Connections: When testing, combine the red and yellow wires and connect them to the positive side of the power supply. Connect the black line to the negative power supply.
• Fuse Check: Replace the fuse with the same type to test the car radio.
• Power Cable: Always use the provided power cables. Do not insert the original car plug directly into the machine if it's not compatible.
• Internal Connections: If the radio still doesn't turn on, the connecting wire might have come off during transportation. Open the back cover to check and reconnect the internal wires.
• Power Cord Mismatch: In rare cases, the power cord may not match your car. You can directly connect the ACC (G3) and 12V (G2) to the positive 12V power supply of the car, and G1 to the negative pole of the power supply.
• Video Confirmation: If issues persist, provide a video showing the power cord connected normally and demonstrating a 12V reading with an electric meter on the connection cord.

2. Why does the car radio show "No Signal" when reversing?

• Camera Connection: Ensure the camera's line is properly connected to the car radio. The video port of the rear camera must be inserted into the "CAMIN" port of the car radio.

3. Why does the camera display "!" and "Can't watch video while driving" when using USB to watch videos?

• Video Warning Setting: Turn off the "Video Warning" function in the settings.

4. Why can't the radio search FM stations?

• Antenna Check: Ensure the radio antenna is inserted. Try inserting the antenna multiple times to ensure a good connection.
• Signal Strength: If the signal in your location is poor, move to an area with better reception and try again.
• Antenna Condition: If the car's radio antenna is broken or ineffective, replace it and retest.

5. Why can't the car radio connect to Bluetooth?

• Pairing Process:
  1. Open your phone's settings, enable Bluetooth, and search for devices.
  2. Find the player's Bluetooth model and attempt to pair.
  3. If a pairing code is required, try "0000", "1234", or "123456".
• Test with Another Device: Try connecting with a different mobile phone to rule out phone-specific issues.
• Antenna Connection: Verify that the Bluetooth receiving antenna is properly connected.
• Reset Bluetooth: If all methods fail, unplug the power plug from the back of the player, wait 3 minutes, and then plug it back in.

6. Bluetooth signal is weak, WiFi signal is weak:

• Antenna Extension: Check and reconnect the yellow rear camera input connector. There are two short cables that serve as extension cords for the Bluetooth and WiFi antennas. You can extend these to enhance the signal.

7. The navigation map does not work:

• GPS Signal: Check if the GPS has a signal by clicking GPS signal detection. If there is a signal, try reinstalling a new map or enabling your mobile WiFi hotspot.
• GPS Antenna: If there is no GPS signal, move the car out of the garage and test the GPS interface voltage on the road. The voltage must be 3.3V; otherwise, the GPS antenna should be replaced.

8. The screen display is abnormal:

• One-key Recovery: Click the one-key recovery button.
• Screen Cable: If the issue persists, remove the screw on the back, check if the screen cable is loose, and reconnect it.

9. Abnormal sound:

• Wiring Check: Check if the original car cable has been modified. If so, inspect the speaker cable and reconnect it properly.
• Original Car/Modification: Ensure there are no conflicts with original car audio systems or previous modifications.

10. Radio setting interface password:

• T6 password: 111333, 1234, 1617, 16176699
• K3/T10/T3L/T3L plus password: 123456, 8888, 7890, 000000
• Programmer interface password: 7890 + current time (e.g., at 11 o'clock, it's 789011; at 12 o'clock, it's 789012).

User Tips

• Android Auto Compatibility: Be aware that certain Android phone models (e.g., Samsung S23, Note 20, S20, Huawei P40 Pro, P30 series, Xiaomi 12 Pro, Oppo Reno 2) may have compatibility issues with Android Auto. Check your phone model before relying on this feature.
• Signal Enhancement: If you experience weak Bluetooth or WiFi signals, ensure the yellow rear camera input connector is securely attached, as its short cables act as extensions for these antennas. Extending them further can improve signal strength.
• Personalization: Take advantage of the multiple free UI options and adjustable button colors to customize the look and feel of your car radio to match your preferences.
