We recently installed the 12.5″ Android Head Rest Monitors into the Honda Odyssey RC1. We previously installed the Teyes CC3 into the car. Using the USB to HDMI video output dongle, we connected the rear head rest monitors to receive video input from the head unit.
The head units are also able to work on its own just like a tab. You can install your favorite apps and enjoy. Each monitor has a HDMI input and output, USB input and also headphone jacks. Besides that, these monitors also come with WiFI and Bluetooth connectivity, just like a phone/tab.
