I ended up finding the entire "control panel" including the vents all the way down to (and including) the Sony radio/climate panel for only $50 from Tapitio Auto & Truck Recycling in San Diego!! They were great, shipped it fast, I plugged it in and EVERYTHING works great again. In my searches I found many other junkyards online selling these for $100-200. People on eBay wanted insane prices for them.
There is a website, www.hollanderparts.com I used, that helps you find parts from junkyards all over the country.
The part number for mine was DT4T 18A802 CB, but there is also one that ends in "CD" that looks the same that would probably work. The part number is on a white sticker on the back of the panel.
By the way, if you have the "ghosting buttons" problem and just want it to stop, all you have to do is remove the panel as shown in the videos in this thread, take the black protective cover off the back and unplug the largest ribbon cable at the very bottom of the climate panel. The giant radio knob/dial will still work. It will only disable the climate buttons and the source and sound buttons. All of those functions can be controlled from the touch screen very easily.
I only went with the junkyard panel replacement route cause I had broken off the cd eject button connector and there is no touch screen button or voice command for that function.
