In this video I install an aftermarket backup camera on my Audi A4 B8 Sedan and show the full process step by step.

The camera is connected to an aftermarket head unit, and I cover everything needed for a clean and functional installation:
- full wiring overview
- routing the camera cable through the car and trunk
- removing trunk trim panels
- connecting the camera to the reverse light signal
- installing the camera in place of the original trunk handle
- testing and final image quality

This guide should help if you want to add a backup (reverse) camera to your car, especially when using an aftermarket head unit.
