I bought the Avic Z120BT and was wondering what the deal is with the Mirror AV option?? When the only rear video it pushes out is DVD,Ipod and AV Sources. The only reason why I got this radio so was that I can store videos and movies on my SD card and watch be able to watch it on my rear screens.. I called Pioneer and they told me that the reason why they took out the feature of pushing out the video from the SD was because the processor couldn't handle it...HUH?... but it can handle it with the DVD?? makes no sense.
