The Head Up Display Control Module (HUDCM) is located inside the instrument panel behind the IC. The HUDCM receives a permanent battery voltage supply via the Rear Junction Box (RJB). The HS CAN comfort systems bus allows for the HUDCM to communicate with other modules such as Head Up Display Cooling Fan Control Module (HUDCFCM) and IC.
The HUD uses laser beams within the module to provide the light source, projecting images stored within the laser diode block, via a collimating lens, onto a liquid crystal on silicone (LCOS) surface, with which the beams have a phase relationship. The light is reflected off through a Fourier lens and a series of 'fold' mirrors to create an image on a rotating diffuser (this reduces speckle effects of the laser light). The light is magnified and distorted, in cohesion with the windshield curvature, and passed across two further freeform curved mirrors, forming the virtual image seen by the driver.
