Possible cause: Unstable voltage / power supply.

• Please check whether the voltage at the connection point is stable at 12V.
• Please check the connections, especially the curved parts of the cable.
• Are you connecting any other devices to the cigarette lighter?

Please send us a photo: the full connection setup (from the cigarette lighter → cable → device).

First, follow the on-screen instructions to install the app. Then:

• Turn off your phone’s Wi-Fi.
• Turn on mobile data and enable your phone’s hotspot.
• Set hotspot name to: CAR
• Set hotspot password to: 12345678
• Phone settings: Settings → App Management → “Mirroring” → Display over other apps → Allow

Note: Steps may vary by phone brand, but the principle is the same.

Your device supports multiple ways to play audio through your car speakers:

1、FM Transmission

• Set the same FM frequency on the device and your car radio.
• Avoid using local radio station frequencies as this may cause interference.
• Supported frequency range: 87.5 ~ 108.0 MHz

2、AUX Connection

• Connect the device to your car AUX port using an AUX cable.
• This method provides the most stable sound quality.

3、Smartphone Connection

① CarPlay

• Turn on Bluetooth on your iPhone.
• Device name: CAR-BT_55B9
• Pairing code: 0000

② AirPlay

• Connect iPhone to WiFi: carplay_wifi_xxxx
• Password: 12345678
• Open Control Center → Screen Mirroring → Select Car

③ Android Auto

• Turn on Bluetooth.
• Device name: CAR-BT_55B9
• Pairing code: 0000

④ Wireless Link

• Scan the on-screen QR code to download the APK.
• Enable floating window permission.
• Turn on phone hotspot and turn off WiFi.
• Hotspot name: car
• Hotspot password: 12345678
• Open the mirroring APK.

Tip: AUX provides the most stable sound quality, while FM is suitable if AUX is not available.

The bracket has an adhesive backing with a dustproof film on it. Please remove the dustproof film before installation.

Cause: This is not a device problem. Netflix restricts screen mirroring (DRM/HDCP), so mirroring may be blocked.

If you want Netflix on the car screen, contact us — we can recommend an Android-based head unit that supports the official Netflix app.

Cause: The reverse trigger wire is not properly connected.

If the system does not receive a 12V signal from the reverse light (positive pole), it cannot detect reverse gear and will not switch automatically.
