After the installation, you need to add 3AG option and do VO coding for your REM and NBT modules. After that you should be able to see the camera when you shift to reverse.
After the installation, I have the following issues:
- The dynamic guide line are not working properly, sometimes the appear for few seconds but then disappear
- The view of the camera is a bit like' fish-eye' (very wide angel). The seller said that this is wide angel to give more wide viewing but my issue is its too wide to the extent it's showing the edge of the car rounded as you can see in the end of the video.

The seller suggested many things to help fix the issue of the guide lines but they didn't work. He even sent a replacement kit with quadlock harness which I tried but it gave same result. So it seems there is an issue causing the module not to read the bus properly so if anyone can help here please reply in comment and it would be much appreciated.
