DIY Non-Nav Harness Extension and files for the circuit board and 3D print cover are posted on GXOR FB. I'll try to post it on here soon, but didn't know how to attach the .zip and 3D print files on here or if that was allowed.

are you still making plug and play harnesses for the conversion? if so im interested
Added a link in the DIY writeup for the print circuit board and 3d print cover files
Here's how I did the same thing. Ultimately everything worked but it was touch and go for a bit with the ac compressor when I initially used the wrong year hvac controller.

2006 Lexus GX470: Convert navigation model to non-navigation?
Is it possible to replace the touch-screen nav/climate/audio system with the non-touch, non-GPS version? My research tells me the wiring harnesses are (very) different. Has anyone successfully made...
I have a Prado 120 from 2008 so which unit do I need and is there a place I can buy the wiring harnessWith the help of MANY people (from IH8MUD to GXOR to google), I'm happy to report that I've successfully converted my GX470 from the stock/OEM navigation/stereo to an android head-unit with non-navigation climate controls. I'll document my experience here...
*** FOR NOW, THIS THREAD WILL BE A WORK-IN-PROGRESS***
(It'll probably take me a few days to a few weeks to properly document everything here, but I'll try my best...)
Huge thanks to Adonis (@JSsinodA ) for all the help! For those who care, I'm not that handy... I've never installed a car stereo before, and the extent of my car know-how is fairly basic (I can do basic suspension, oil changes, tire rotations, etc.)... POINT BEING, if I can do this, pretty much anyone can... JUST MAKE SURE TO GIVE YOURSELF ADEQUATE TIME AND DON'T BE IN A RUSH! I completed this project over a three-week period, most of which my GX dash was completely ripped apart... it looked like I was driving a stolen car.
Final product:
Steps that I will cover:
Anyhow... I'll start including details when I have time!
- Purchase Parts!
- OEM climate controls / brackets / bezel ~$200
- Headunit - AliExpress Android 8.1
- Backup Camera
- Antenna Y-adapter and micro-adapter
- USB inputs
- Test your OEM climate controls once you receive them from salvage yard - Need to make sure they work!
- Back-up camera - Run the lines
- Install Non-nav climate controls
- Trim climate controls so that Android head-unit will fit
- Extend the wires (7 required... 1 additional to make life easier)
- Illumination fix - Splice wires to ashtray light
- Install new Android head-unit
-----------------------------------------
STEP 1 - PURCHASE PARTS!
1. OEM Non-nav climate controls, brackets and bezel - Sourcing these parts can be challenging... I'm in Southern CA and with the help of others, found them at a scrap yard in Texas. It cost me $225 to get the climate controls, bezel and brackets removed from the donor car and shipped to my doorstep.
Below are the OEM Lexus part numbers for the non-nav climate controls, listed by production year... (I lifted this directly from @theferg post below... he is also a great resource for this conversion!). It is essential that you get the right part number, otherwise the controls won't work properly.
88650-60770 (11/2002 - 10/2004) (folks have also seen an 88650-60B50 for these years as well)
88650-60771 (11/2004 - 07/2005)
88650-60772 (08/2005 - 12/2005)
88650-60773 (01/2006 - 07/2009)
You can find your production year in the drivers side door jam label:
(Also note that those with production dates on the switch-over months--ending/beginning months--seem to kind of have a crap-shoot of a time figuring out which one is the actual one since some sites list the production dates slightly differently. This list I posted has been spot for the good handfuls that have done this on GXOR fb page.)
When you finally get the climate controls, you can find the part number here:
2. Aftermarket head-unit - The common choice is the 9" Android head unit from AliExpress (China). You should get the 8 Core 2G 32G CANBUS version... it ran me $250 shipped, and arrived in about a week or two.

Theoretically, once you do the climate control conversion, you should also be able to choose a double din HU from a more common manufacturer (i.e., Alpine, Kenwood, etc.)... I believe that Crutchfield sells new bezels and mounting hardware for non-nav versions of the GX470. But personally, at $250, the above Android HU is worth trying out... that's what I went with, and so far so good.
3. Backup Camera - I used the following camera, but honestly I'm not that happy with it... It's just not that clear, and comes in a little grainy and streaky (if that makes sense). But ultimately, it works.
Amazon product ASIN B07HNRYHZ6
4. Antenna Y-adapter and micro-adapter

5. USB inputs
I am no SparkieDo you still make harnesses or am I asking the wrong person?
Still making the harnesses? I am interested in one.
I had the most success emailing Eldar. zemeapp AT gmail.com
Good luck.
Good luck.
Interesting mod to install aftermarket hu into a factory nav setup. Still requires a bit of work, but you don't need to buy the non-nav components. And doesn't look as clean. But as those other parts get harder to find, this is an alternative option.

Yes! It is possible to install a modern aftermarket radio with wireless Android Auto and Apple Car play in your GX470 with navigation and the Mark Levinson sound system. This was possible thanks to the Beat-Sonic amp interface adapter. MVA-81. I installed a single DIN 10 inch head unit that swivels. The steering wheel controls work too."
