It all started with a dream. An enterprising
What the modder basically did was add an HDMI connection to the Droid Bionic's car dock to match the Micro-HDMI output on the side of the Bionic handset, which enables the Bionic's video mirroring function. Then, with an HDMI-to-RGB converter and a digital video switch, the mirrored video is distributed to the Lexus' in-dash display and dual 9-inch headrest monitors.
Because this is just a video output, the Lexus' in-dash touch screen can't be used to control the Bionic. However, the setup is still useful for displaying Google Maps Navigation on the display and piping turn-by-turn directions through the car's speakers. As a nice bonus, the Bionic's Webtop interface can also be invoked with an onscreen menu. Of course, the initial goal of streaming Netflix video to the back seat is also accomplished.
