Is it necessary to install a head-up display?

If the financial conditions permit, it is recommended to install a head-up display. As for whether it is mandatory, it depends on the personal preference of the car owner, and it is difficult to give an accurate and consistent answer. The head-up display is a very useful feature. After installation, it can greatly improve driving safety. The following is an introduction to the head-up display: 1. The main function of the head-up display, as the name suggests, is to project navigation, speed, Bluetooth phone calls, ADAS driving assistance system prompts, and other information onto the front windshield using the principle of optical reflection, and it can also display them in color. This allows the driver to avoid looking down at the dashboard, further enhancing the safety and comfort of driving. 2. If the brightness of the head-up display is too low or the information is too cluttered, the entire head-up display can have the opposite effect.

That day on the highway, I almost rear-ended another car just because I looked down at the navigation for half a second. Later, I installed a heads-up display (HUD), which projects speed and route directly onto the windshield, so I don’t have to take my eyes off the road at all. Especially when driving on mountain roads at night, I no longer get blinded by the glare from the dashboard. I recommend frequent long-distance drivers to install one—it’s expensive, but your life is worth more than a few thousand bucks. The latest HUDs can even display speed limit reminders and lane departure warnings, acting like an extra electronic co-pilot. Once during a heavy rainstorm, my rearview mirrors were completely fogged up, but thanks to the HUD’s navigation projection, I didn’t miss my exit.

To be honest, for commuters, the head-up display is most practical during traffic jams. During rush hour, staring at the navigation for route changes often makes you miss the car in front starting and getting honked at. After installation, I found that oil temperature and fuel consumption info are all displayed floating, so a quick glance at a red light lets you know the car's condition. Once, when I was almost late dropping off my kid, the navigation projection directly showed the turning distance, so I didn’t need to look away at the center screen. The only downside is that aftermarket versions require a reflective film on the windshield, which can cause slight ghosting on sunny days. I’d recommend going for the entry-level clip-on version—it’s around a thousand bucks and gets the job done.

After evaluating the cost-effectiveness of dozens of HUDs, let me break them down into three categories: OEM optional HUDs start at 5,000 RMB, but they offer the most stable integration with dashboard data; aftermarket brands under 2,000 RMB, I recommend the windshield projection type, avoiding those with plastic reflectors that age easily; the cheapest phone-mounted type costs only a few hundred RMB, but it can only display navigation and is hard to see in daylight. If you frequently drive on highways, go for it without hesitation, but for city commuting, it's really unnecessary. One thing to note: low-end HUDs can be too bright at night and cause glare, so remember to buy one with auto-brightness adjustment. For wiring modifications, always go to a professional shop—I've seen cases of blown fuses due to improper wiring.

The needs for HUD differ completely between urban commuting and long-distance road trips. In city driving with an average speed of 30 km/h, the HUD is mostly useful for displaying speed, with limited utility amidst frequent traffic lights. But during my last road trip to Western Sichuan, it was a lifesaver—on winding mountain roads with continuous sharp turns, the navigation arrows floated right by the cliff edges to point the way, making it ten times safer than looking down at the center console. It’s even more noticeable when driving on highways at night: traditional dashboard backlighting is too bright and strains the eyes, while the amber glow of projected fonts is far more comfortable. Now, even entry-level cars priced around 100,000 yuan offer HUD as an option. My advice? Consider the type of roads you frequently drive on before deciding.
