Hit me up if you have any questions. the wiring diagrams are all in the description of the video. I did the HVAC myself. Had the stereo shop install the radio
I believe this can be removed if you are no longer using the factory head unit. I removed it during the Nav Delete and everything works fine. It allows extra space for cables behind the new head unit.
For some of you, it might just be the motor. I replaced mine and it worked no problem. Easy part to get...Check ebay and the normal toyota parts sources.
Here is the video I did on the install. Takes about 20-30 min....An hour if you are a klutz like me.
