Calibrating a virtual image projected from a vehicle HUD system onto a windshield includes displaying a fiducial at a predetermined location upon the windshield, projecting a test image from a test image generator within the HUD system, aligning the test image with the fiducial, determining a positional deviation from a test image calibrated position required to align the test image with the fiducial, and based upon the positional deviation and a known positional relationship between a virtual image calibrated position and the test image calibrated position, aligning the virtual image with the fiducial.
