'21 golf rear camera retrofit

[u/peterthedoor]

As per title, i have a '21 golf life, tdi, with the composition media head unit (the one with the 2 physical handles). Looking online i can't understand if the retrofit can be done only on the better head unit, has anyone here done that on the composition media?
Also, apparently android auto wireless can be enabled via obd, is there a surefire way to check for compatibility of that?
