Certain functions are standard, others are optional - the range also varies depending on the market.
Navigation in the menus is carried out using buttons in the centre console or with the steering wheel's right-hand keypad.
Depending on the function the cursor is on when EXIT is pressed, and on the menu level, one of the following may occur:
- phone call is rejected
- current function is interrupted
- input characters are deleted
- most recent selections are undone
- leads up in the menu system.
Short and long press may produce varying results.
A long press leads to the highest menu level (main source view), from where all of the car's functions/menu sources can be accessed.
