I see that you sell the adapter, are there any guides, or videos on how to install the adapter? will I retain 100% of the original functionality of the camera with the adapter installed?
It needs to connect all cables correctly, and you must connect as required. There is no way to provide a unique guide, because every Volkswagen model is different.
The red wire is connected to the ACC12V of the fuse box.
The yellow wire is connected to the positive of the reversing light.
The black wire is connected to the ground wire.
The blue plug is inserted in the lower left corner of the back of the unit.
26-pin plug, connect to your OEM camera.
This is a very mature product, as long as your connecting wires are correct. It can work normally. This installation is not too difficult.
I suggest you don’t hide the cable first, you can connect every wire ，then test it first, if there is no problem, you can hide the cable again. When testing, the trunk must be closed.
