I'm not the first to do this, pucker5 posted a few days ago without pics. There was talk about it before, I just didn't try it. But I did today.
This comes from prius people and I found some other info from avalon forums also.
If you put a 68 ohm .5 watt resistor on the C plug pins 9 and 10, (blue and pink on 2006) everything works as it should and you can take the stereo out and put whatever you want in that slot.
The middle plug, C, has the tx wires, that's where the resistor goes. Blue and pink wires.
the other two plugs can stay unplugged. (A and B)
Obviously there are some conditions. The power antenna won't work. Put a fixed tundra antenna in. The rear seat audio won't work, delete it and put some UBS chargers in there. Steering wheel buttons won't work, Get the PAC universal for your aftermarket deck so they do. CD changer doesn't work also. That's it far as I know.
Personally I have a kenwood media shallow mount deck, a JL and a RF amp to two sets of speakers in the doors and a 10" punch sub in the back in it's own box.
I do not use the stock SUB wiring, sub box, or the HU stock wiring to the speakers at that connection.
I do use the stock speaker wires where they come out of the stock amp under the pass seat.
My stuff is wired as if it was a fresh install except using the speaker wiring at the output of the stock amp.
The point is that you can delete the OEM deck and all climate controls work the way they should.
I wish I had a female socket so I wouldn't have to cut the harness, but I did anyway and everything is fine.
I only use the display for back up cam. It never comes on except when in reverse. I put the climate screen on and took a pic so you guys could see. Everything works fine. I tested and measured before I cut the harness.
I'm going to alter the stock silver face to accept a ISO DIN HU maybe tomorrow.
Yes the bottom buttons work. defrost, rear AC etc.
