Car Windshield Display: The Best Windshield HUDs
A car windshield display puts your speed and driving data on the glass, right in your line of sight. Compare the best windshield HUDs for any vehicle.
A car windshield display is a head-up display that shows your speed and driving data on the
windshield, directly in your forward view. Also called a windshield HUD, it uses a
HUD projector to reflect the readout off the glass so you never look down.
Why drivers add a windshield display
- Eyes on the road — speed and alerts stay in your line of sight.
- Universal or data-rich — GPS without an OBD2 connection, OBD2 for engine data.
- Quick install — plug in, position on the dash, drive.
- Auto brightness — clear by day, dimmed by night.

Choosing a windshield display
If you want the broadest fit, choose a GPS windshield display; for engine data on a compatible gas car, choose an
OBD2 one — and check its fitment list first. Either way, place it low so it never blocks your view. Explore every type in the
HUD display for cars guide, or jump to
speedometer HUDs and OBD2 HUDs. Check fit with
