Hi Guys,
My dad picked up a 2015 Limited 4runner. Came with the premium Entune. We thought, before purchase, that it was going to allow DVDs to be played. Apparently that was possible on older models, but not the current model. It was disappointing that there wasn't an easy way to feed video into the head unit. But alas, we have discovered a feature that isn't really disclosed in the shoddy documentation available for this thing. Heres what it took to play video from his iPad mini:
Lightning to HDMI A/V adapter

HDMI Cable
HDMI to RCA converter (found at my local radioshack)
RadioShack HDMI to Composite Converter - Radioshack
Some RCA couplers
Amazon.com: Female to Female Gold RCA Coupler Joiner Adapter Pack of 10: Electronics
RCA (Yellow, Red, White) to 3.5mm TRRS cable

Note: The Red and the Yellow RCA plugs have to be swapped due to the tip, ring, ring, sleeve configuration on the head unit.
Plug this bad boy in to the aux 3.5mm jack next to the usb input connector and you should be good to go.
Also picked up the prestige unit so he doesn't have to mess around with the lockouts.
Big thanks to Toyota for making this one so mysterious. What put me on to it was: when you select A/V input on the head unit, it displays a 3.5mm jack with the TRRS instead of just TRS separators. Go figure. Don't even bother asking a toyota salesman about this sort of thing unless you enjoy being lied to.
Hopefully this benefits someone else.
Enjoy!!!
