Function Description
The PLINTBL7 serves as a comprehensive car stereo receiver, integrating multiple functionalities for an enhanced driving experience. Its core functions include:
- Navigation: The unit comes with pre-installed navigation software. Users can set a default map if multiple maps are available and access the navigation interface directly from the main screen.

- Video Playback: The unit supports 1080P HD video playback from an SD card or USB interface. The video player allows switching between different storage locations (All/SD/U Disk/File Browser) and automatically resumes playback of the last played video file. Controls include menu access, last/next track, play/pause, and full screen mode.
- Wireless BT (Bluetooth®): The device supports Wireless BT 4.0+ for hands-free communication and audio streaming.
