How It Works

The signals used to generate the image in the head-up display are input from the corresponding control units, e.g. multi-audio system controller (M-ASK) via the K-CAN and MOST data buses to the electronic circuitry in the head-up display. The electronic circuitry evaluates the incoming signals and forwards the prepared image information to the components in the head-up display.
