I took my 2014 Mazda 3 to the dealership today and it was determined the CMU was dead and needed to be replaced. It is not the screen, it worked fine. It will cost about $1,000 to have it done at the dealership.
Is it possible to do this on my own?
If so, how difficult is it?
Is there someplace I can find step-by-step instructions on how to replace it?
Where can I find a new CMU?

Thank you in advance.

There is a used one from a 2016 on craigslist in my area, they are asking 350.00
Instructions can be found in the service manual.


On a side note (last year) I took my 2015 in for a software update and it died during it. I was under warrantee but they did cover it.

Do you what the model number is and the date of manufacture?
