- Radio Antenna Adapter: For connecting the factory antenna to the universal radio antenna interface of the new stereo.
These accessories can typically be found by searching for your vehicle's year, make, and model online. Muhimu: Voltage of this car stereo is 12V. It is not compatible with 24V systems found in large trucks.

Kutatua matatizo
This section addresses common issues you might encounter with your SJOYBRING Car Stereo. If you experience problems not covered here, please refer to the Warranty and Support section for assistance.
Head Unit Powers On Briefly, Then Shuts Down
Tatizo: The head unit powers on for a few seconds and then automatically shuts down.
Sababu inayowezekana: Some cars' ACC (accessory) wires are controlled by a CANbus system or have a "delayed shut off" feature, which may not provide stable 12V accessory power to the radio.
Suluhisho:
- You may need to purchase a specific harness adapter (e.g., from brands like "PAC") that provides stable accessory power for your car model.
- Alternatively, you can locate a stable ACC power source elsewhere in your vehicle and connect the red wire of the stereo's harness to it.
No Memory Function After Power Off
Tatizo: The car stereo loses all settings (radio presets, time, etc.) every time the car is turned off.
Sababu inayowezekana: The ACC line (Red wire) and the B+ line (Yellow wire) were reversed during installation.
Suluhisho: Correctly connect the Red wire to the switched 12V power source (ACC) and the Yellow wire to the constant 12V power source (B+). Refer to the "Wiring Diagram" in the Setup section.
Display Sporadically Turns Black
Tatizo: The screen occasionally turns black, but touch sensor and audio functions still work.
Sababu inayowezekana: In some cases, the power drawn by the front camera when set to "always on" might interfere with the display interface function.
Suluhisho: Access the system settings and change the front camera setting from "always on" to "off". You can also try resetting the unit by inserting a paper clip or push pin into the tiny reset hole next to the USB port on the left side of the unit. This may temporarily restore the display, allowing you to change the setting.
