Hello again, I had several problems with the service activations of Mercedes me. Now I wonder if I still have problems with the services. (OTA) I would like to install the sound “Roaring Pulse” . To this it is said: A –Roaring Pulse–soundscape can also be activated after an over-the-air update. But no matter how I do it instead, I don’t discover this update anywhere. Do you have a tip on how to get the sound, or can check if the OTA function is active is and works? Thank you!
