Can HUD be installed as an aftermarket accessory?
4 Answers
Heads-up display systems can be installed as aftermarket accessories, but the retrofitted ones cannot display much information, mostly only showing engine speed and vehicle speed. Here are some relevant introductions about heads-up displays: 1. Display information: Some high-end cars come equipped with heads-up display systems from the factory. These original equipment manufacturer (OEM) heads-up displays can show a lot of information, such as vehicle speed, navigation information, and currently playing songs. 2. Function of installation: The heads-up display projects information onto the windshield, allowing the driver to focus on the road ahead. The heads-up display system can enhance driving safety.
Yes, you can definitely install a HUD. I installed a domestic HUD on my old car last year. Now I don't need to look down at the dashboard while driving - speed, navigation arrows, and speed limit signs are directly projected onto the windshield. However, you should be aware there are two types: standalone and projection. The standalone type just places a projector on the dashboard - cheaper but may cause glare. The projection type requires replacing with a specially made windshield - more natural effect but three times more expensive. Don't attempt installation yourself - have professionals handle the OBD port power connection to avoid damaging the car's computer. With a budget of 2,000-3,000 RMB you can get one installed. For mid-to-high-end cars, it's more convenient to have the dealership install genuine parts.
Installing a HUD (Head-Up Display) afterward is completely feasible, but it depends on the effect you're aiming for. A basic one that projects just the speed onto the dashboard can be done for around a hundred bucks. For a professional experience, you'll need to spend a few thousand on a full AR navigation system that connects to the car's computer to read data. I recommend opting for big brands like Bosch or Garmin for better compatibility. Installation position is crucial—poor angle adjustment can cause ghosting, and the curvature of the windshield can also affect the image quality. Extra caution is needed for cars with ADAS systems, as improper wiring might interfere with the millimeter-wave radar. Over time, you'll find it most useful for night driving, as it eliminates the need to constantly shift focus between near and far distances.
Adding a heads-up display (HUD) is definitely doable, as aftermarket products are quite mature now. The basic principle is to project instrument data onto the windshield in front of the driver's line of sight. There are three main types on the market: the reflector type is the cheapest but takes up space, the windshield film type has average clarity, and the direct projection type offers the best effect but requires replacing the windshield. I recommend installing one with a speed warning function—the numbers turn red when speeding, which is very noticeable. The key to installation lies in hiding the wiring. Connecting the power to the cigarette lighter is the safest option, while connecting to the fuse box might drain the battery. After two years of use, I've found the biggest benefit is avoiding speeding tickets, as the speed numbers constantly in view serve as a great reminder. During the rainy season, remember to regularly clean the lens; if it gets fogged up with moisture, the installation would be for nothing.
