Guys, help needed with the voice command system please. The in-laws have the latest C-Class and have an issue with getting the voice operation for the telephone system to work. How do they use the voice command to bring up the phone book to make calls etc? On my last C-Class and my current E-Class, I can access the phone book or telephone commands, simply by pressing the voice operation button on the steering wheel and speaking a command, such as 'call name' That switches the screen to telephone mode (irrespective of what the screen display is showing) and I can access the phone book, make calls etc. On their car, saying 'call name' does nothing? The screen was on sat nav when I tried it this evening and pressing the voice command button just showed all the commands for operating the sat nav only? I was loaned the new shape C-Class a couple of week ago which I paired my phone to and I'm sure it worked the same way as the older C-Class? Any ideas why it won't recognise telephone commands?
