Engineering Menu/Mode how to access w246-062015
I have a Class B year 06/2015 (w246) and did a "stupid thing" in my Media system (NTG5 I think). I accessed a menu using Red Hang + 3 + "*" and entered this menu (Screen) that I sent. But I ended up clicking "Set to Shipment Mode" then simply turned off the entire system and the radio started to "blink".
Well, to solve this, I disconnected the car battery. However my media system seems to have entered a default system. And I lost some settings like controlling the vehicle's internal lights.
My doubt is, how should I proceed to return to these functions. Is there a way to enter the Engineering Menu / Mode for this car?
Can someone help me ?
Tks
