Hi from a newbie in Australia, I have a 2017 GR Sport Gen 4 import. Bought it for my wife as a first step into electric transport. It has not got the original head unit, and I would like to replace the retro fitted Alpine head unit with a suitable 7" model with wireless Android Auto....Does anybody know what's needed to allow the rear view camera to see 180°? Other than that, there seems to be a lot to learn. Cheers, Oigleman
