Hello my fellow Az people would like to ask if anyone has done any displays in there rearview mirrors. One thing tho I'm interested in the people that don't have 2 way mirrors ? My car apparently Dosent come with one because there's no display up there normally. (2002 a4)
I want to put a temp display up there but I would like to keep the reflective part of the mirror, only let light pass though. I believe if I take two way mirror tape and retape my mirror this would work?

Have searched some but there's always a million links to people that already have two way in there mirror.
