2017 CX-5 GT CMU Part Number?

I managed to brick the CMU on my wife’s 2017 CX-5 grand touring (tried to upgrade the firmware on my own). The dealership wants $1200 to replace the CMU.

I’m shopping around online trying to find a unit from a salvaged car. I’m not having much luck using the term CMU. The few units I have found are usually listed under infotainment screen.

Does anyone know the part number for the 2017 CMU?

I believe I found the CMU from a 2019 CX-5 but I can’t be sure if it’s compatible. Anybody know if these CMUs are compatible?

I installed the 2019 CMU into my 2017 and installed the new cables at the same time. Everything works fine. Only snafu was the language was all in French and metric because I bought the part from Quebec. Easy fix. It already had the 700 software update so I didn’t even need to update the software.

I bought the part for $65. It was listed as a Bluetooth radio. There is a sticker on the back with the Bluetooth frequency. That’s probably why it was sold by salvage yard as a Bluetooth radio. Saved over $1000.

Nice find!!
 
Simply deleting Mazda from Bluetooth settings on phone and letting phone find new Mazda allowed Bluetooth to work. Apple CarPlay works fine with my iPhone. Seems there is no discernible difference between model year parts. Hope this helps other people.

I second the thank you for posting problem and solution here. It's great to know it was so straightforward to swap. I'm confident swapping mechanical components, but this stuff is a gamble.
 
The CMU part number the dealer gave my was KB7W669CO-K but the unit I purchased from a 2019 model was a KN3L669CO (K2352). My best guess is that they changed the part number to indicate the date of manufacture but they are identical parts.
