Engineering mode
Hi, I'm new to mercedes and I've just bought an early 2016 e250 cdi 212 model. I've been trying to access engineering mode and having no luck. Can get dealer mode. Tried the 3 buttons and nothing happens. I only want access to enable reverse camera. I'd like to fit an aftermarket camera. Can anyone help?

thanks
James

Are you talking about COMAND head unit Menu?
Good luck enabling aftermarket camera into stock gear...

​​​​​​FYI: Whatever you decide, resiste the urge to play with the "Factory Reset" option. This will soft-brick your unit, causing it to require professional SCN services.

yeah, I'm talking about the head unit. You can easily install an aftermarket camera, I just need access to the engineering mode to make the rear cam available. I tried the 3 buttons but it won't do anything

If you have a NTG 5 head unit, I don't believe you can access engineering mode. I have an e350 w212 with NTG 5.0 and there are no codes to access the engineering mode.

​​​​​​I watched a video about the factory reset and then the combination to get into engineering mode. Are you sure it will soft break? How does this happen
