Apart from App radio, there are HUs with mirror link. For your situation, if you have a smart phone, could you use a video out from your phone and some sort of splitter?

Yeah I have a Galaxy Nexus with HDMI output and the MHL adapter cable and also the Motorola Atrix with the HDMI adapter cable but I don't want to use a phone and an HDMI to Composite converter, I want to get a composite video out signal and run one 2 conductor cable from the OBDII to the head unit. If I wanted to use a phone that would be simple, or a tablet etc., but I have the Touring with Navi pkg so I'd like to use that 2nd video input I paid 200.00 for! I got the backup camera video lockout adapter off EBay that everyone is using in a backup camera thread somewhere....It has two video inputs that are composite to RGB converted for the TFT display. One input is for backup camera and the other is for any video signal-it's not locked out during car movement so would be perfect for OBDII display...
