XLE 8 inch to 12.3 inch infotainment swap?

This is one part you don’t want to buy new because it costs more than the car. Get it from eBay or a junkyard.

 

The mechanical fit is probably OK. Perhaps you might need some trim. However, the firmware will probably conflict with the firmware of the multimedia computer, as it has a different screen resolution and aspect ratio unless the system can automatically adjust for the screen resolution and aspect ratio as in a plug-and-play device. There might also be a way to change the settings by using a communication tool though.

 

Hi all,

I've been watching this thread for a while now and I have some good news to report!

Using the info Ryan Kim had posted about his experience with the swap, I bought a used XLE 12.3" head unit (86100-47850) off eBay and attempted the install using the existing 8" wiring harness. I'm happy to to say that everything works including the volume knob and volume control on the steering wheel! Just like Ryan predicted, if you have an XLE or LE with the 8" head unit you HAVE to use the 86100-47850 unit so you don't lose control of your volume adjustments due to the internal vs external amplifiers.

The only thing that is a bit strange is getting connected to Toyota Connected Services. When I start the car, it automatically loads the profile of whoever owned the head unit before me. I can still connect my phone and use Android Auto, but right now there is no way to delete the existing profile and login to my profile. I also can't add an additional profile. Strangely enough however, it seems like all the functions on the Toyota App are still working and reporting my mileage, tire pressure, and door/window status.

I believe the issue with the Connected Services is that head units are linked to the VIN of the vehicle so this may require a trip to the dealership to go through the VIN verification process and link this new head unit to my car. Not sure if they would even be willing to do that for me. Or maybe I can hard reset the head unit somehow, start fresh, and re-login to my profile? Let me know if any of you have insight towards this!

 

Good to get confirmation that its a plug and play. I just ordered an 86100-47850 off of eBay to do the same retrofit to my 24 Prime XSE.

FYI - All these ebay auctions list a VIN the unit is off of. You can plug that into Toyota's free vin decoder (Toyota VIN Decoder - Find Vehicle Specifications By VIN | Toyota.com) to confirm if its a Limited/XSE Premium screen (47860) or XLE/LE/XSE screen (47850).

 

OK, I got this done today. Took about 9 minutes start to finish, easiest mod in the book.

@Evannnn96 what was interesting in my install is that it pulled up my saved profile and immediately loaded it, no issues.

I just installed the 12.3" infotainment screen on my 23 LE and everything works great (aside from the Toyota Connected Services, which I'm not interested in anyway, and no profiles show up in settings) Ended up finding one on eBay for around $900.

I made a simple tutorial for anyone else looking to do the swap on their LE on my website:

Big thanks to Ryan Kim for doing all the research on this prior.
