2.3 Navigation Voice Guidance Customization

Realize humanized voice broadcast settings to ensure clear and unobtrusive navigation prompts:

• Voice Volume Ducking: Enable the GPS mixing function. The system will automatically reduce the volume of background music and media playback when navigation voice broadcasts, ensuring clear voice prompts.

• Broadcast Frequency: Adjust advance reminder distance for turns, lane changes and highway exits; set dense reminders for complex intersections and sparse reminders for straight sections.

• Voice Style & Language: Switch multiple voice tones, support real road speed limit broadcast, speed violation reminder and fatigue driving reminder.

3. Multimedia Audio & Video Customization

The car multimedia system supports personalized adjustment of audio effects, playback modes and video settings to create an in-car entertainment experience that matches user preferences.

3.1 Audio Effect Professional Tuning

Enter Multimedia > Audio Settings for refined sound quality customization:

• Sound Field Adjustment: Fine-tune the front, rear, left and right sound field balance to adapt to the driver's main listening position and improve surround sound effect.

• Speed Volume Compensation: Enable automatic volume adjustment. The system will intelligently increase the volume with the increase of vehicle speed to offset road noise and wind noise.

3.2 Playback Function Customization

• Media Source Priority: Set default playback source (Bluetooth music, USB flash drive, local music, radio) after system startup.

• Playback Mode: Customize single loop, list loop, random playback and automatic pause/resume functions.

• Radio Optimization: Adjust stereo mode and signal sensitivity for urban and suburban driving to reduce radio signal noise and improve listening clarity.

3.3 Video & Screen Customization

• Set video playback resolution and screen scaling mode to avoid picture stretching and blurring.

• Enable driving video lock screen (safety setting) to prevent video playback while driving and ensure driving safety.

• Customize screensaver wallpaper, startup animation and standby display information.

4. Smartphone Interconnection Customization (CarPlay & Android Auto)

Realize seamless connection between mobile phone and car machine, customize interconnection functions and interface layout, and improve the convenience of mobile navigation and multimedia linkage.

4.1 Connection Preference Settings

• Enable automatic Bluetooth connection and automatic CarPlay/Android Auto connection. The car machine will automatically identify and connect the bound mobile phone after startup.

• Turn on device memory function to save commonly used mobile phone equipment information and avoid repeated pairing.

4.2 Interconnection Interface & App Customization

• Home Widget Layout: Drag and sort commonly used navigation, music, weather and calendar widgets to customize the main interface display content.
