Head-Up Displays (HUD)
Project speed and navigation onto the windshield to keep eyes on the road
A head-up display projects key driving data like speed and navigation onto the windshield or a small combiner screen, so you can read it without looking down. Aftermarket HUDs typically pull data from the OBD2 port or pair with a phone app over Bluetooth. The goal is to keep your eyes forward and reduce glances at the dashboard or phone.
Brightness in daylight, the clarity of the projection, and how well it reads your vehicle's data are what set good units apart. We curate top-rated picks on Amazon so you can compare OBD2 and GPS-based models, display size, and mounting style. Confirm your car has a compatible OBD2 port if you want live engine data, since GPS-only units show speed but not vehicle diagnostics.
