In the midyear change 2011.5 fx35 with the power rear liftgate, they've removed the auxiliary jack in oder to cut cost. Ive been looking for the rca cable part because i have a sneaking suspicion that it will be plug and play since there are empty ports in the back of the head unit right next to where to USB port plugs in but i can't find the part #. If anyone can find it for me i would be forever grateful.
As for usb, i use a program called Xilisoft Ultimate Converter 6, but you can use any program that converts files into DivX AVI.
If interested, Ive played around with video settings and finally found the best settings that doesn't make the video laggy or choppy on the infiniti screen, because the built-in receiver of the infiniti is not very good.
As follows:
You need to convert to a Divx AVI file
720x480 resolution or less is what the screen will play, all others bigger than that will give "file unplayable" error.
Bitrate should be set to 4500kbps or less. Anything higher, you run the risk of the video being choppy because the average the system can handle is only 4k kbps with a peak of 8k kbps, but ive found with everything ive played i can get away with setting my films and videos at 4500 kbps average. You can try 5k kbps, but you're walking a thin line there. A couple of my videos were still choppy at 5k because the peak's were constantly hitting at or above 8k. So it depends how intense of a video you are watching.
FPS should be set at 24 fps or less. Any higher, the system can't handle and the video will be choppy and laggy.
Audio on the video can be set to whatever. I always set it to highest.
And those are the best settings that I can find after tweaking for literally DAYS.
