I'm hopeful someone will figure out how to get the JBL working. I know I could go through and change out all of the speakers and amp then do the swap but if I can avoid it I'd like to.
Why the reason for the “basic, non JBL, non NAV” if going through all this trouble to change the unit?

That sucks to hear. I was hoping that it would be a more direct swap/retrofit and assumed it was based on skimming other posts. Would you happen to know the part #s for the hazard harness and AC vents? Please also keep us posted on the lost USB function.JBL is an entirely different beast and I would rather keep my options open for OEMaudio later than corner myself into JBL.
A few things to note. You do need an new harness along with the Hazzard switch. It will plug in (odd shape but still clicks in) but your hazzard will just flash non stop. Also, not sure if my conversion harness is 100% correct but I lost USB and I have two spare openings on the Entune 3.0 unit and only one remaining plug on the harness available but it matches none of the two available plugs.
Also, the side pieces next to the AC vents are different also and require trimming to fit. I may just buy those as well. I did not see any of this mentioned prior so I figured it was worth mentioning now.

Ok so an update. After speaking to Brian at AutoHarness it appears my USB adapter harness was missing from my order so we have to figure out replacement and then I should have USB. According to him there is also a remaining unused connection point at the back of the head unit. I will show in pictures once I get to my laptop.
As far as Hazzard switch, harness and side vent trim.. I had already ordered the hazzard switch from a 2021 model. The new head unit switches are narrower than the ones used on the 2014-2019 and will not fit the housing. They are also keyed to the housing differently and are more of a soft touch on/off vs the click type we have. I did not anticipate the harness also being incompatible so I do not have a part # on that yet. I believe the side vent trim is part of the unit and not sold separately as I am not seeing it separated from the unit on toyota parts website.

You can make the vents work aa it is just the side trim that needs the raised edges and the small nipple cut off to seat where it looks right. It could still sit back 1mm for my OCD nature but you would be hard pressed to tell by looking. The emergency flasher is an entirely different situation. It is hard to know if I just received a bad switch or if it is the harness. I suspect harness though. I messaged AutoHarness to see if they could look into this as this conversion will more than likely require a hazard conversion harness also unless you score a salvage unit with all the trimmings. Mine came from a 2021 that had the T10 installed and that requires removing the side trim, hazard switch + harness as well as the top plate so that is what made my situation a bit more complex.I just received my harness from AutoHarnessHouse and a 2020 head unit. Unfortunately, I am still waiting for the navigation jumper harness that did not come with the head unit. Hearing about the hazard switch and the vents is making me second guess this conversion...
Also may have found the harness for the emergency flashers. I ordered it and will report in once I get it in hand. I suspect the harness should work as those that have done the transplant with all the bits intact have not reported issues. For reference just to document and help others:

thanks for the info itll be helpful if I can find a head unit at a reasonable price. Pending where it comes from some appear to have the hazard switch (ebay). The radio trim/bezel is most likely included with the radio and there isnt a part number?
The trimming of the vent bezel doesnt seem like too much of a problem, just curious to exactly what you trimmed.
On the vent side piece trim.. I had to trim some bit of plastic around the plastic mounting protrusion as the shape is a bit different until it was just a circular insert. They still sit about 1/1.5mm out from normal. I may have to take them off and just slowly file the plastic mounting post down so that it sits a bit closer but it really is hard to tell. I just need to be conservative as if I screw one up there is no replacing them (come as part of the unit).
I have no pictures of the back side of the trim but this is how they sit in the unit after trimming.if you have a chance get some pictures of it, thx

I did it! I found a salvage 2020 non-JBL nav head unit and I have successfully retrofitted it into my 2012 TE!
