Connectivity and Linking
Connecting External Devices
The monitors support various external devices via HDMI, USB, and SD card slots:
- HDMI Input: Connect smartphones, Amazon Fire TV Sticks, or other HDMI-enabled devices for high-quality video and audio. An HDMI adapter may be required for some devices (sold separately).
- USB/SD Card: Play multimedia files (videos, music, photos) directly from USB drives or SD cards up to 32GB.
Linking Two Units
The two monitors can be linked to display the same content. Use the provided 3.5mm interface connection cable to connect the AV OUT of one monitor to the AV IN of the other. This allows passengers in both rear seats to enjoy the same movie or content.
For displaying content from a single external HDMI source (e.g., a smartphone or Fire TV Stick) on both monitors, an HDMI splitter (sold separately) is required. Connect the external device to the splitter, and then connect the splitter's outputs to the HDMI inputs of both monitors.

This diagram explains the connectivity options. Two monitors can be linked for synchronized playback using AV cables. Additionally, external devices like smartphones can connect via HDMI (with an adapter) to a splitter (sold separately) to display content on both monitors.
TV Viewing
To enable TV viewing, an external digital TV tuner (e.g., EONON V0051, sold separately) is required. Connect the TV tuner to the monitor's AV input.

Wired Headphone Support
Connect wired headphones to the 3.5mm headphone jack on the monitor for private audio listening. (Headphones are not included).

Home Use
The monitor can be used in a home environment with an optional AC adapter (EONON POA025, sold separately). This allows for versatile use beyond the vehicle.
