How to Reset the Rearview Camera on an Audi A6?

I recently had some work done on my Audi A6 and now the rearview camera seems to be malfunctioning. It's not displaying anything and I can't seem to get it to reset. Any tips on how to fix this issue?

To reset the rearview camera on your Audi A6, start by checking the fuse for the camera. If it appears to be intact, try disconnecting the battery for a few minutes and then reconnecting it. This often resolves any technical glitches with the camera system. If the issue persists, it may be a faulty camera unit and you should bring it to a certified Audi technician.

First, check if the camera lens is clean and free of debris. If it's dirty, use a soft cloth to wipe it clean. Then, try resetting the MMI (multi media interface) system by pressing and holding the power button for about 10 seconds. If this doesn't work, you may need to have the camera recalibrated at a dealership.
