Hello Everyone, just joined, and just bought a 2017 GLA 250 last night and the multi-media system buttons on the center console (Radio, Media, Navi, etc.) are not back lit so you cannot see the buttons at night. I have searched through the menus and everywhere else I can think of in order to turn on or increase the button illumination, but no success at all. These should light up right? What am I missing?
