What are the hazards of installing a HUD in a car?

The hazard of installing a HUD in a car is that it affects the driver's line of sight. The following is a related introduction to car HUDs: 1. Definition: Head-Up Display, abbreviated as HUD, is also called a flat-panel display system, which refers to a driver-centered, blind-operation, multi-functional instrument panel. 2. Function: The HUD can project current speed, navigation and other information onto the photoelectric display device on the windshield, forming an image in front of the glass. The driver can see navigation and speed information without turning or lowering their head. 3. Types: Divided into suspended HUD and dashboard-mounted HUD. The suspended HUD is fixed on the sun visor above the car driver, which results in the HUD information being projected onto the upper area of the windshield. The dashboard-mounted HUD is fixed on the center console in front of the driver, which determines that the HUD information will be projected onto the front area of the windshield.
Adding a HUD may seem high-tech, but don't underestimate its risks. With over a decade of driving experience, I've seen many cases: improper placement causes ghosting and glare on the windshield. Strong sunlight creates blinding reflections during the day, while at night it becomes too dark to see the road clearly, instantly blurring vision and making it easy to miss pedestrians or obstacles. Worse yet, excited novices may focus on navigation info while ignoring road conditions, doubling accident risks. Unprofessional wiring during installation can cause short circuits and blown fuses - failure to start the car is minor, but battery explosion or fire would be truly dangerous. I recommend choosing reputable brands rather than cheap knockoffs from Taobao - safe driving is no joke.
Be careful when installing a HUD. I recently helped a friend install one, and the process was quite troublesome: First, you have to dismantle the center console and windshield area. When wiring, you need to connect it to the car's original circuit. If you're not skilled, poor contact at the wire ends can trigger the car's alarm system or even burn out the onboard computer module, costing thousands to repair. The key issue is that DIY installations often overlook compatibility. Cheap HUDs have low resolution, causing shaky images that lead to eye strain and headaches on long drives. If the projection shifts and blocks your view, the distraction could cause a rear-end collision, which isn't worth it. Over time, the device ages quickly, and maintenance costs can pile up to be more expensive than the original factory option. So, I advise everyone who really wants one to go to a professional shop and get a certified, compatible model—it’s more worry-free, cost-effective, and safer.
