Android screen for my Mercedes CLA45

I want to install an Android screen in my 2015 Mercedes Benz AMG CLA45 that supports all built-in buttons, knobs, controls, and the camera, while offering wireless Android Auto.

I’ve received quotes from popular labs, hubs, planets, garages etc., across Dubai, ranging between 2.7k ~ 3k AED for 12.3-inch screen with 8GB RAM and a 1 year warranty.

I’m not sure if I should keep looking for vendors outside Dubai for a cheaper price.

Has anyone here installed special Android screens in older Mercedes cars that fully support all built-in buttons, knobs, controls, and the camera?

Your input will help me make a better decision rather than jumping to whatever is closest to my doorstep in Dubai.
