Question on Rear Display and MMC Link
 

If you have the MMC and the rear display linked and there is something playing on the AUX port on the rear display can you click rear display on the MMC and have the feed from the AUX port on the rear display displayed on the MMC? Also assuming you want this function when the car is in motion would this be a 3rd patch or would it fall under the MMC Aux in motion patch.
