Installation Guide
Wiring Connections
This car stereo operates on a 12V power supply. Ensure your vehicle's electrical system is compatible. For vehicles with a 24V system, a voltage converter is required (not included).
If the clock and presets are lost after turning off the vehicle, it indicates that the constant power (B+) and accessory power (ACC) wires are incorrectly connected. To resolve this, swap the red ACC wire and the yellow B+ wire. The yellow wire must be connected to a constant 12V power source (always hot battery post) to retain settings.
Backup Camera Installation
Connect the included HD backup camera according to the following steps:
- Connect the red cable (1) of the camera power wire to the positive pole of the car's reversing light cable.
- Connect the black cable (2) of the camera power wire to the negative pole of the car's reversing light cable.
- Connect the Reversing Trigger Wire Cable (4) (often pink in color) from the stereo harness to the red cable (3) which is an extension of the video input wire.
- Connect the video signal cable (5) from the camera to the 'CAMIN' input on the stereo unit.

For complex wiring or if you are unsure about the installation process, professional installation is recommended.
Operating Instructions
Power On/Off
To power on the unit, turn your vehicle's ignition to the ACC or ON position. The stereo will automatically power on. To power off, turn the ignition to the OFF position.
Touch Screen Interface
The 9-inch IPS touch screen allows for intuitive control. Tap icons to select functions, swipe to navigate menus, and use pinch-to-zoom gestures where applicable.
Wireless CarPlay and Android Auto
Connect your smartphone wirelessly to access CarPlay or Android Auto. This allows for navigation, music playback, hands-free calls, and text messaging directly from the stereo screen using voice commands like "Hey Siri" or "OK Google".

Bluetooth Connectivity
Pair your mobile device via Bluetooth for hands-free calling and audio streaming. The built-in Bluetooth module allows you to import contacts and play your favorite playlists directly through the car's speakers.

AM/FM/RDS Radio
Access local radio stations using the integrated AM/FM/RDS tuner. The RDS (Radio Data System) feature provides additional information such as station name and traffic updates where available. Scan for stations and save your preferred frequencies as presets.
USB Port Functions
The USB port serves multiple functions: fast charging for your mobile devices and playback of media files from a USB flash drive. Simply connect your device or drive to the USB port to access these features.

Mirror Link and Online Video
Utilize the Mirror Link function to display your smartphone's screen directly on the stereo. This allows for viewing navigation apps, videos (for passengers only), or other content from your phone on the larger 9-inch display. The unit also supports direct online video playback.

EQ Audio Adjustment
Customize your audio experience with the built-in 7-band equalizer. Adjust frequency bands to enhance bass for hip-hop, clarify treble for podcasts, or select from preset modes like Pop, Classic, Rock, and Jazz to match your listening preferences.
Steering Wheel Control
If your vehicle supports steering wheel controls, you can configure them to operate the stereo. This allows you to adjust volume, skip tracks, answer calls, or mute navigation without taking your hands off the steering wheel.
Backup Camera Operation
When the vehicle is shifted into reverse, the stereo automatically displays a clear, night-vision feed from the included HD backup camera. Parking guidelines appear on the screen to assist with safe maneuvering into parking spaces.
Maintenance
To ensure the longevity and optimal performance of your car stereo, follow these maintenance guidelines:
- Cleaning the Screen: Use a soft, dry, lint-free cloth to clean the touch screen. Avoid using abrasive cleaners, solvents, or chemical sprays, as these can damage the screen surface.
