A HUD apparatus for a vehicle includes a HUD patch defined upon a reflective surface of a windshield of the vehicle. A virtual image generator projects a virtual image within the HUD patch. An image sensor is coaligned with the virtual image generator and has a field of view including the HUD patch. A controller is configured to receive, from the image sensor, a HUD patch image, and to adjust the projected virtual image based upon the HUD patch image.

A composite pane, includes an outer pane having an outer-side surface and an interior-side surface, an inner pane having an outer-side surface and an interior-side surface, and a thermoplastic intermediate layer, which joins the interior-side surface of the outer pane to the outer-side surface of the inner pane. The composite pane has, between the outer and inner panes, a sun protection coating, which substantially reflects or absorbs rays outside the visible spectrum of solar radiation. The composite pane has, on the interior-side surface of the inner pane, a thermal-radiation-reflecting coating (low-E coating). The composite pane has a transmittance index A of 0.02 to 0.08, wherein the transmittance index A is determined according to the following formula A=TL.sub.composite glass pane/(TL.sub.low-E-coated pane*TE). TL is the light transmittance and TE is the energy transmittance measured according to ISO 9050.
