The DV712 is a DVD Multimedia Receiver with Bluetooth® featuring a 7" Touch Screen Display, designed for in-vehicle entertainment and communication. This unit supports various media formats including DVD, CD, USB, and microSD cards, allowing users to enjoy audio and video content on the go.
Function Description
The core function of the DV712 is to provide a comprehensive multimedia experience in a vehicle. It integrates a DVD player, AM/FM tuner, Bluetooth connectivity for phone calls and audio streaming, and multiple auxiliary inputs. The 7-inch touch screen display serves as the primary interface for controlling all functions, offering an intuitive user experience.
The DVD player supports DVD Video, DVD+R/RW, and DVD-R/RW discs, as well as CD-DA, CD-ROM (ISO), CD-R, and CD-RW. This allows for playback of both video and audio discs. For digital media, the unit includes a USB port and a microSD card slot, enabling playback of MP3 audio files and viewing of AVI video files or JPG photos. The unit is designed with a safety feature that prevents video display while the vehicle is in motion, requiring the parking brake to be engaged for video functions to operate.
The AM/FM tuner provides access to radio broadcasts, with the ability to store preset stations across multiple bands. Users can toggle between local and distance tuning, and stereo and mono modes. The AS/PS (Auto Store/Preset Scan) function allows for automatic scanning and storage of the strongest stations.
Bluetooth connectivity is a key feature, enabling hands-free phone calls and wireless audio streaming. The unit supports auto-connect and auto-answer features, enhancing convenience and safety while driving. Users can dial numbers directly from the touch screen keypad or access their phone's contact list. Bluetooth audio allows for streaming music from a paired device.
The DV712 also includes auxiliary inputs for connecting external audio/video devices. A 3.5mm auxiliary input is located on the front panel, while rear RCA A/V inputs provide additional connectivity options. A dedicated rear camera input allows for the integration of a rearview camera, which can automatically display the camera feed when the vehicle is in reverse or be manually selected.

Maintenance Features
Proper maintenance ensures the longevity and optimal performance of the DV712.
- Installation: It is highly recommended that the unit be installed by a professional installer or authorized dealer due to its technical nature. Ensure secure grounding to the vehicle chassis.
- Environmental Considerations: Avoid installing the unit in areas exposed to direct sunlight, excessive heat, dust, dirt, or excessive vibration.
- Fuse Replacement: When replacing a fuse, always use a new one with the prescribed rating (10 amp ATM mini style fuse). Disconnect the wiring harness first to prevent short circuits.
- Cleaning the Monitor: Use only a dry silicone cloth or soft cloth to clean the monitor. Avoid stiff cloths or volatile solvents like paint thinner and alcohol, as they can scratch the surface or remove printing.
- Liquid Crystal Fluid: If the LCD is damaged and liquid crystal fluid leaks, avoid touching it. If contact occurs, wash it off with soap immediately, as it can be hazardous.
