My understanding from having read other posters on other forums is that you basically have to form your own dash component. Form it, as in craft it... make your own fiberglass mold and literally create it. Buy a dash insert and mod it yourself.
OR, chop a hole elsewhere in your dash, in a location where you can just cut without having to re-form.
Given that both of those are big projects, we decided to go with one of those flip-out versions - a Pioneer. It has Apple Car Play capability and it was not cheap.
But the screen quality sucks. It's too dim during the day, too bright at night, and the programming logic is impenetrable to the point of making the thing almost useless. Retrospectively, we should have gone with the dash re-forming route so that we could get a head unit of better quality.
Some pics... too dim during the day (Garmin beside it for comparison)...
...and too bright at night (that being true whether its set to maps or music or whatever). Look at how much brighter it is relative to the Garmin and the iPad below. Slogging through the menu, there might be a way to adjust that, but like I said, the logic is impenetrable.
is someone's build album for a Sprinter. Not your vehicle, I know, but you can get the general idea of the process from this.
