The display is excellent. The audio quality on my device is excellent. The installation process is quite straightforward. The integration of Google Maps and Spotify on Android Auto is exceptional. The expansive display enhances the interior's modernity. I am quite pleased that I obtained mine. The processor is rapid as I acquired the highest specifications.
Each screen manufactured is tailored for the particular original device. The greater the popularity of the original unit, the more options available for finding your new screen, including price, processing speed, supplier, and, most critically, the functionality of the new device.
I will share images of my screen in operation; however, please note that this pertains only to an MMI 2G High for a B8 A5, and I cannot comment on any other device.
If you are interested in a unit, it is advisable to visit Aliexpress and add it to your wishlist. Aliexpress will thereafter inform you when a sale occurs (I acquired mine for £246).
Best of luck
