2012 Mazda2 OEM Radio pinout / schematic / wiring diagram requested


I am searching for the pinout / schematic / wiring diagram for the OEM stock radio for the 2012 Mazda Mazda2 vehicle.

Radio model number: 14797439
OEM radio from the dealership.

I have spoken with both the dealership's parts department as well as their OEM vendor; neither have the schematics and resort to 'replacing damaged components' only as opposed to repairing components and as such do not carry the unnecessary diagrams.

If anyone has pinouts of the radio: Please share a URL, hand drawn image, explanation of each pin / function or other.

Thank you, very much!

Thank you, in advance! :)
