I bought a Pioneer AVH P4300DVD in May and learned that my iphone 3G was not supported. I waited until the new iPhone was introduced and bought it. I connected the phone and I still do not get any picture...no YouTube, no Apps, nothing... The DVD player works and I can hear everything else, I just do not get a picture. With my 3G I was able to play YouTube but could the Apps would not work. Any suggestions? Thanks.
