CID & CON: Central Information Display And Controller

The preset brightness of the head-up display can be individually set using the CID. The brightness adjustment (= difference between set value and basic setting) is stored in the head-up display through the Car and Key Memory.

The CID can be used to select which information is displayed in the head-up display (e.g. Check-Control messages, navigation instructions).

The controller is the control element for selecting setting in the CID.
