I just posted my workaround to get Video output from my iPhone to Kenwood DNX8120 in another post. I assume this will also work with AVIC F units. I hope someone will try it and report it back.
I have been messing around with my DNX8120 and my iphone. Like some of you I was frustrated with the lack of video support for my iPhone. I finally got it working with the Apple Composit AV Cable and a few adaptors. I am posting here because I think this solution will probably work for the AVIC users. The total cost is around $57. This can replace the standard Kenwood/Pioneer ipod cable ($30). I pay $27 more but now I get video output.
NOTE: I think the Pioneer iPod cable for AVIC F Series output with PHONO connectors. I assume you can just replace the standard cable with the Apple cable without any connectors.
Instruction:
I had the original kenwood interface iPod cable that I purchased with the DNX8120. One thing I know in the new iPod Touch and iPhone is that they require an authentication chip in the cable to output video. Basically instead of using the Kenwood Ipod cable, I replace it with the Apple composit video cable ($49). The Kenwood cable output both audio and video with 1/8" AV jacks. The Apple Composit Cable output in phono jacks (red, white and yellow). I purchased from radio shack two adaptors for about $8. One takes audio (Red and White cables) phono jacks and convert them into a stereo 1/8" jack. For the video I got an adaptor that convert it into mono 1/8" jack. Now connect everything back with the new cable. Well everything is working. See the pictures attachments.
Important NOTE:
I notice sometime the video won't come on. I spent the last two days to make sure I understand why. I finally figure it out. When you want video to output from the iPhone or iPod Touch, you need to make sure the "IPOD Accessory Attached" screen is on your iPhone. Please check out the attached video. If you are really stuck try to reset the iPod application by holding down the HOME button in IPOD application for 5 secs and try it again.
Good luck. Let me know if you need any help.
