Once we confirm an update is available, we’ll send you a link with:

  • Reference video
  • Card software installation files
  • Firmware update package

How to update (4 simple steps):

  1. Prepare a 16–64GB SD card, the card software, and firmware file (from the links).

🔌 What should I do if the connection to the car screen is intermittent?

  1. Turn off Bluetooth and WiFi on your phone, then restart both your phone and the device and try again.
  2. Clear your phone’s memory and reconnect.
  3. Make sure the power cable is plugged in firmly. Please use the original charging cable.

🔊 How to avoid noise?
For the cleanest sound, use Bluetooth to connect to your car’s audio system.

🎧 Why is there noise when connecting AUX to the car’s audio system?
Noise through AUX is usually caused by ground loops or electromagnetic interference (EMI).

  • Ground loops happen when two devices are connected to the same ground point through different paths, creating a small voltage difference that can cause buzzing.
  • EMI comes from other electronics in the car (like alternators, lights, or radios) and can interfere with the audio signal.

How to fix it:
Using a filter can help:

  • Ground loop isolators break the unwanted electrical path while letting audio through.
  • High-frequency filters block interference from other electronics.

If you're hearing noise through AUX, a simple inline filter can often solve it.

⚙️ What should I do if the CarPlay screen won’t turn on after multiple restarts?

  1. Check that the power cable is plugged in securely — use the original charging cable.
  2. Avoid using a 2‑in‑1 car charger, as it may not provide stable power.
