Here is my objective-
I'd like to do a transplant of the stereo and aux cable, so that I can gain the USB port from the Corolla stereo, as well as Bluetooth, handsfree, etc...
I attempted to do the swap and both units had the 10 pin and the 6 pin. But it looks like the 2012 Corolla HU has another 28 pin plug, while my 2007 4Runner 6 disc in dash changer has a 20 pin plug. Is there any way to make this work? I saw wiring diagrams in the other threads, but not really anything on either of these plugs.
I should note that when I tried hooking up the corolla head unit into my 4R, the only things that weren't working were steering wheel controls and Bluetooth audio
