Microphone is not connected and vehicle and driver settings grayed

Hello everyone I need help just bought this 2017 Tacoma trd but it came with some issues I got cheap knowing the issues
1-Microphone is not connected message I can not pair my iPhone
2-back up camera won’t display in my stereo screen
3-Driver settings is grayed
4-Vehicle settings is grayed
5-volume control in the steering wheel don’t work
So I took it to 2 different stereo places and they told me most likely is the estéreo unit then I found a couple used same model number I connected everything but still have the same problem I was able to turn on drivers settings that’s it luckily the person let me try the stereo before I buy it. If you see last picture the 2 top middle slots mark with an X didn’t had anything connected I when I remove the head unit to I connect the other one so I wonder if anything goes there and if that might be the problem I didn’t find any other connections inside.
Does anybody had or have the same issue and how you fix it my other option is to get a stinger or any other stereo I Hear very good reviews about stinger but it cost like $1300 see pictures
Thanks

 

Did you try removing the negative terminal of the battery, waiting 10-15 minutes, and then re-installing?

 

Very strange! Did this truck have any dash work done? It's almost behaving like someone mucked around with the dash / radio unit and then screwed it up when they put it back together. Good luck OP, I'm sure you'll figure this out.

 

Try resetting the radio. I believe you have to hold in the power button.

 

I did try disconnecting the battery and reset the radio no luck

 

In mine when I switched out the head unit, I remember seeing an orange plug in the factory wiring harness labeled microphone. It might have came unplugged behind the radio.

 

I will check today hopefully is that thanks
