After some trial and error I finally figured out how to get this mysterious A/V input to work!
(IS350 F Sport)

Here is what you have to do...

1) Get a 4 Pole 3.5mm jack to composite cable (commonly called a camcorder A/V cable, which you can purchase at radio shack) such as this one:




2) Get a composite (a/v) coupler like this:




3) Connect the wires like this (white wire to red on coupler, yellow wire to white on coupler, red wire to yellow on coupler):




4) Plug in your component device. I used a dvd player to test it out.




If you want to plug in an iPhone like I do then here is what I'm going to try tomorrow and I will update you on how it goes.

Also, if you want to unlock your entertainment/nav unit while you're driving, I highly recommend getting one of these

I have it on my 2011 GS 350 and it works great! You hit the volume buttons on the steering wheel to enable/disable it (vol down X2, vol up X2)

ENJOY!

Both of those will get you where you need to be

Iphone 5, 5s, 5c, 6 video playback on the 3GS

It really works!

Thanks gennacide for this useful info. I am glad you posted the idea of the coupler and I found the post. My use case is dash cam position setup but it is really disappointing to see the lack of info in the Lexus manual.

Here is a good reference for those who want to know why a coupler is needed in some cases - there is no universal standard for the pinout assignment. This picture only shows some of the "standards".

That's really interesting I've always wondered why devices that used this cable only worked with the specific cable they came with. I wonder why they wouldn't standardize it.

First of all just wanna give you a great shout out , been dying to do this and now it finally works !! This is just what I was looking for and thanks for the detailed instructions on how to set it up !!! Thanks again !!!

So this would allow screen mirroring through the A/V section in the on-screen display? Does this work while the car is moving? Seems awesome for like $30!

No it's more than that , you gotta buy the beatsonic dvd bypass module so you can watch while driving and then everything he mentioned after ! I'm glad I got it and so worth it !!

Took a few minutes but i got it! Thanks Gennacide.Still get a bit of static and need to find a less bulkier HDMI cable.
Excuse the picture, its from snapchat. Forgot to take a better one with the iPad

gennacide

No problem!! What adapter are you using? It looks different than mine.

Also, try this hdmi cable. It fits perfect through the side of the console because it's flat.

sdotk

The adapter is the same one you have, the apple one. It is at an angle in the picture so you can't see how wide it is.
The flat HDMI cable would be perfect, gonna have to find one that is way less than 50 feet!
Thanks again bro!

So much great info in this thread. By any chance does anyone know if this will work on a 2015 IS250 F Sport?

Thanks in advance.

I'm assuming this does not work for non-navigation 3IS?

I noticed a couple owners ask about it so I tried to do some digging myself. Just found the online manual for the display audio unit (non-navigation): http://drivers.lexus.com/t3Portal/do.../sec_05-01.pdf

They're incredibly vague about why it might not function with a regular 4-pole AUX cable, so I have doubts that it ever works.

sdotk

It should.
You would need all the wires listed above plus beat sonic nav bypass system.

gennacide

Ohh gotcha. The one I ordered was 1.5ft lol.
