Hey Opelrsx,
Sorry for late reply.
I didnt manage to get it to work. Is your supplier using the same box or the bigger one with MOST capability?
If your supplier showed that they could get it to work on their test vehicle, then they'll be able to show you how to connect.
Some notes on my side, i connected everything, but it seems we haven't get to activate the signal to turn on the front camera and side. My ANH20 has the button on the right side which to activate the camera on stock HU. But since the original HU replaced, the Park Asssist (PA) Unit didn't receive any signal to activate the camera hence we unable to get video footage.
At these that is what I suspect as the camera is controlling the signal to PA ECU.
Do contact your supplier and share some info so that I can test out on my end also. I still got the thing attached to my vehicle though.
