Well folks, I´d have to tell this upgrade is terrific. Yes, the car looks much more updated, and a little more c118ish (thou obviously not equal) with this large screen, with plenty whistles and fireworks that the OEM screen does not even dream to have. Pls see attached video.
However, be warned that being me kinda used to install, connect and modify things, the installation is a PITA.

PROS:
- Full Android 10 functions (you can download whatever app you want)
- Android Auto compatible
- Carplay Compatible
- 4G Sim slot if you ever want to have the car to be fully internet independent and/or provide a hotspot to passengers
- Touch screen, which makes MUCH easier navigation, phone calls, Etc.
- You can have either Android view, OEM NTG view (5.1 in my case), or a split screen of both.
- FULL CAR INTEGRATION (All knobs, steering switches, radio controls work perfectly after install, BOTH on NTG and Android worlds)
- In my case (I do not have COMAND, just Radio 20 with HK pro sound system), it provides me the huge view of speed/RPM gauges
- You can get up to date maps through google maps or Waze for free

CONS:
- It is quite expensive ($ 550 + Sh&H)
- Hard installation process
- It comes without any installation or connection manual; I had to figure it out and study in the web for some 4 days
- If you use the android phone app for calls (you can also use the original one), it forces you to use a small, regular quality external speaker (provided). I´M LOOKING FOR A WAY TO FORCE ANDROID TO PUSH THAT AUDIO TO THE AUX OUT (Car´s amplifier). Any help will be much appreciated

Bottom line:
If you are willing to spend some $ 600-700, and either spend a couple of days fiddling with your car or pay for installation, it is a very rewarding update/project.

Enjoy!
