Problems after factory reset on Mercedes C-Class

Hello everyone, I have a 2019 Mercedes C-Class and I recently performed a factory reset via the dealer menu. Since then, I have lost several important features such as the rearview camera display, ambient lighting, and various safety and assistance systems. I have also noticed the absence of some engine data. Has anyone ever encountered this problem or have any advice on restoring these features? Thanks in advance for your help!

Check if there are any software updates available for your vehicle's infotainment system. Sometimes a factory reset can revert the system to an older software version, causing features to disappear. If updates are available, install them and see if this resolves the issue. Let me know how it goes or if you have any further questions!

Unfortunately, my car isn't offering any updates... What should I do?

Try disconnecting the car battery for about 10 minutes to reset the system. This can sometimes restore lost features after a factory reset. Make sure to have your radio code handy if needed. Let me know if this helps or if you have any further questions!

Check the vehicle's fuse box for any blown fuses related to the infotainment system and electronic features. A blown fuse could be causing the loss of certain functionalities. Replace any faulty fuses and see if this resolves the issue. Let me know how it goes or if you have any further questions!

At first glance, it seems like an update that I should have done at a Mercedes dealership. What do you think?
