HUD A501 OBD2 Smart Car Head-Up Display

Your car's vital signs, always in view.

Product Description

Stop glancing down at your dashboard and start keeping your eyes where they belong — on the road ahead. The HUD A501 projects real-time vehicle data directly onto your windshield at eye level, transforming the way you interact with your car's information.

Plug directly into your vehicle's OBD2 port for instant access to speed, engine RPM, water temperature, oil temperature, turbo gauge, and security alerts — all displayed in a bright, easy-to-read projection that adapts automatically to day and night driving conditions. No wiring, no drilling, no complicated installation. Just plug in, position, and drive with more information and less distraction than ever before.

Studies consistently show that head-up displays reduce the time drivers spend looking away from the road. The HUD A501 brings that benefit to any car made after 1996 — which means almost every vehicle on the road today.
