Every C-Class gets at least a 7.0in colour screen mounted nice and high up on the dashboard that’s operated by a rotary controller between the front seats. Entry-level SE trim doesn’t get sat-nav as standard, but all other versions do. Up to, but not including, the C63 models, this is a relatively crude Garmin system that feels like it’s running as an app on top of the Mercedes software and is clunky to operate.
The C63 versions get Mercedes’ own Comand Online system, which is available as an option on many of the lesser trims. It’s without doubt slicker and easier to use than the Garmin system and comes with an 8.4in, higher-resolution display, plus an additional touchpad controller. This isn’t as intuitive as BMW’s iDrive system or Audi’s MMI system, though.
A digital radio is standard on all models, as are two USB sockets in the centre console. An upgraded Burmester sound system is an optional extra on all but entry-level SE models.
