Just making a quick post about adding a 2020+ headunit with Android Auto/Apple Carplay into a 2014-2019, specifically into my 2015 SR5 PREM with navigation, non-JBL. All you need is a headunit and a transplant harness. I know I could've gone aftermarket headunit but I like installing OEM as much as possible. The headunit I picked up was used so a lot cheaper than buying brand new from the dealer. Keep in mind you need a specific head unit depending on your model and what you are looking to purchase. In my case it needed to have navigation and be non-JBL. JBL models will have a slightly different install I believe. Auto Harness House can help if you have any questions.

I purchased the plug and play transplant harness from AutoHarnessHouse - Custom Car Stereo Wiring Kits. Here is the specific link to the product;

Here is the headunit straight out of the box. In great shape except for a couple minor scratches.

I am still waiting for the harness but I will update here once received.

how much did you spend on the head unit? Is there an adapter for the hazard light connection? I'm still looking for a oem head unit to install in a 2017. Best price I've come across lately is about $800 . Currently using the sony 8100 and love it but really want an oem look. Are you going to try for wireless carplay if so recommendations on device to use?

Yes I spent around that much. If you shop around you could probably find a better price. I didn't shop around as I understand these are not easy to come by so I snatched up the first one that suited my requirements.

I could be wrong but I believe you would use the OEM connector from existing harness for your hazards. From what I can tell it is the exact same as older models. Will update once I get the harness to install.

I was also looking at the Sony 8100 as it has the advantage of an HDMI port. The only thing I didn't like is you lose all OEM functions (but gain Carplay and AA). With the OEM headunit you keep OEM functions and have the added bonus of Carplay and AA which you can switch back and forth whenever you want. I believe both Sony and OEM headunit is WIRED Carplay/AA so no advantage on either side. I plan to use the wireless adapter but have not decided on which one yet as there are quite a few options out there. Trying to figure out a way to have both audios from USB and plugged in Android Auto/Wireless adapter dongle at the same time...

Just finished installing the headunit and everything works! The only thing I noticed is the hazard button works but does not stay on. Does anyone know anything about that?

Take your old hazard button and install it. I have a 2021 and a 2017. 2017 feels like an on/off vs the 2021 temporary contact switch feel

What is the part number for your newer head unit? Thanks.

Where did you source the HU

The one that worked for me is 86100-35640. Mine is a 2015 SR5 PREM with navigation, non-JBL.

Used unit off of EBay. You can also checkout LKQOnline or local social media markets.

I documented what I did to fix the hazard button issue. Just posting here for future reference in case anyone attempts this in the future.

@NB17Limited

just bought one off ebay for a decent price. It doesnt have the vents though, will I be able to reuse my current vents? As for the hazard button I can reuse that just need to trim it

Yes it looks like the vents are exactly the same.

did you reuse the old hazard button ?

Yes I used the hazard button and it's surrounding trim bezel from old unit.

Is there a way to customize the startup and or screen OFF image on these newer headunits? Was able to do this on my 2015 but can't seem to find any info when searching. Only results show for 2019 or older. Thanks!
