Head up display compatibility

[OwerlordX]

Hi!
I would like to get a hud in my audi a4 b7 Avant but as I see the most sites don't write this car in the compatibility list for their hud (it's from 2009 models everywhere). But the car has an obd connector of course which is the connection type of the hud. The question is will it work or not?

EANOP Mirror HUD is what I looked btw.

Thanks.

The B7 doesn't have full CANBUS capability whereas my understanding is the B8 and later do. Really need EANOP to confirm which model years of vehicles they support.
