Engineering Mode
So, I will send you some images therefore you can easily see how to enter this mode and use it

To enter this mode, you need to do these simultaneously :
red phone button , 1 ,# .Press these at the same time and hold them 10 secs . You can gain access bluetooth, phone ,TA,radio functions and settings .
The image below shows phone settings :

This image below is about system settings :

Now, this is about phone volume level , if you think your phone volume is too low , you may need to use these settings :

This image below shows earphone settings , you can change them if you like .

This is about equalizer :





This image below is about listening to music thru your phone's bluetooth connection :

I could enter to the Engineering menu in my E class Coupe with Audio 20, but when I activate Bluetooth external Features and reboot the system, it stays in off again.
is there any way to reset the system and add AutioStreaming??
Engineering mode is where you can enable the internet connectivity that Mercedes claims isn't there

A quick way to understand if it's enabled already, is to try to stream audio via BT to another device. Have you done so?

Thanks for stating the obvious. On the other hand, why would I buy and install a camera if I cannot find where the option is to turn it on? Once I figure out how to turn it on, I will buy one and install it.
So back to my original question, does anyone know where to go in this engineering menu to turn on the back up (rearview) camera option?
Thanks,
Gus
