I have a Citroen C5 from 2012, the 2.0 model, and recently I performed a factory reset on my media system (myWay model). However, after the reset, I noticed that the Park sensors no longer appear on the screen.
Unfortunately, my car doesn't have a button to enable or disable these sensors, but they used to show up on the multimedia screen before the factory reset. Now, I only get sound alerts when I'm in reverse.
I tried to do some research, and it seems that I may need to re-enable the sensors using diagbox. However, the problem is that nobody in my town has diagbox except for the Citroen authorized service, and they want to charge me 80-100 euros for the service.
This got me thinking – instead of paying for the sensors to be re-enabled, why not purchase a Chinese Android unit and install it in my car along with a rear camera? The challenge is finding a good 7-inch multimedia unit that fits in the same space as the old screen. I found one on AliExpress here: https://www.aliexpress.com/item/1005004 ... 4itemAdapt
The seller sent me this image and mentioned that if the size matches, it should work:

So, my question is, has anyone ever installed an Android head unit like this in their Citroen C5, and does it fit properly in the space of the old 7-inch screen?
Beside that my car doesn't save language change, its stuck on French. When i change from wheel control to English its would stay for 2-3 min and back to French... I can think only that is issue with ECU
