The improved HUD design utilize liquid crystal displays (LCD) and light emitting diode (LED) technology, which convey brighter images and are less expensive to manufacture.
Automakers encourage car owners with HUD windshields to replace them with original equipment (OE) when necessary. The windshield is specially designed to correctly project the HUD image. Installing anything other than an OE replacement windshield may result in the HUD appearing as a double image according to automakers.
While a vehicle with this technology hasn’t made it into our shop, with the increase in popularity, we know it’s only a matter of time before one does. Delta Kits President Brent Deines shares his approach to completing repairs on this type of windshield, “Delta Kits always recommends following manufacturers recommendations for specialty windshields,” said Deines. “However it should be noted that there are now many aftermarket HUD devices and phone apps that do not require a special windshield or coating so only vehicles with factory installed HUD displays that require specialty windshields are cause for concern.”
Before starting a repair, it’s important to check the identification markings on a windshield often called the “Bug”. In most cases the Bug will provide a wealth of information about the glass manufacturer, the American Standard “AS” number, the DOT number, the M number and if there is HUD technology. The bug can be found in the bottom center
passenger side of the windshield.
