Ok guys I really hope someone can help me out. I want to be able to view my iPhone 4s on the AVH p4200 however after hooking up the AV cables and the usb on the back of the unit the audio does not play only video however after removing the usb the audio works fine however I would like to have my phone charging while viewing my phone (youtube,web ect....)

 

I was informed about the cd-iu200 and vcd-iu201v and notice it uses the AUX cable to hook it up and it charges the phone and plays (songs and videos) however does it allow you to have a display out option for those who have jailbroken iPhones so we can view everything.
