if you were to get the RCS video (and audio) signal from the phone, then you could use the aftermarket devices (i think DICE does it) and pipe the video (and audio) into the AV input for the unit... I know i can pipe any RCA video source into the factory TV module's AV input...

the question would be, how to get the AV signal out the phone... i never thought of it, but it seems like an idea... i am off to ebay to search chinese sellers for AV cable!!!
