Every Mercedes GLC gets a 7in colour screen mounted high up on the dashboard, which is controlled using a rotary dial and touchpad between the front seats. You’re better off sticking with the dial most of the time; it’s quicker and easier to use on the move than the gimmicky touchpad.
SE models miss out on sat-nav, but are 'pre-wired' so it can be installed easily at a later date. Meanwhile, Sport and AMG Line models come with a Garmin-based navigation system as standard, which does the job but in a rather clunky fashion.
The optional (and very expensive) Comand system is easier to use and slicker, and brings a larger, higher-resolution display. However, the menu system still isn’t particularly easy to fathom compared with BMW’s excellent iDrive; some simple tasks take longer than they should – even when you’ve learnt the system’s quirks.
