Can someone tell me how I can adjust the after-time (time from turning off the engine to the autom. turning off the mobile phone) ? Currently my mobile phone does not turn off independently. In my E-Class this went somewhere with the vehicle settings. I can’t find this option with my R. For some other MB classes it works by entering in the mobile phone book as the name “after-time” and as the telephone number a number between 1 and 10, so that the after-time is between But it does not work on the R. Who knows advice ?
