Ferrari FF 2013 Head unit upgrade

Hi everyone.
I am new in the club, just received my first Ferrari last week.
I want to change head unit to aftermarket, because I want better navigation and my current works not properly: even when I use USB, it regularly stops sound. Also I am thinking to upgrade sound, but still not decided (total upgrade will cost about 6k)
I have visited the local tuning company and they gave me full quote for that, but recommended and head Alpine ilx-w650 (not sure about their quality because it cost on Amazon 300$)
Here is full quote:
He recommend using the Alpine ILX-W650 unit that was recently released. It's a powerhouse of a headunit and offers a ton of great features.
This also includes the Alpine Type X component set, subwoofer and 4 channel / mono amp to power everything. Pricing would be looking at $6500 for everything. I'm also attaching a photo of a prior FF we've done with a similar head unit.

But I want to have better head, like this one:

Will it be okay for Ferrari FF?
And what would you recommend to upgrade sound?
Thank you
