Hello
I bought this unit from
https://www.iceboxauto.com/audi-a8-1...d-51-hl-8818gb
Once I receive it i will write a little install guide and a review so others can see if they like it etc.
I'm not affiliated with the above company and there's nothing about these android radios online so this should help a lot of people.
It's made to be a direct replacement for rns-d so no cutting and sanding requried!
