Why drivers choose it
It delivers the core benefit of a head-up display — information where you’re already looking — in an OBD2 + GPS HUD that’s quick to set up and easy to read day or night, with automatic brightness so it never dazzles you after dark.
Easy setup
- Plug in. Connect the cable to your car’s OBD2 port (under the dash, driver’s side).
- Position. Place the display low on the dash so it never blocks your view.
- Drive. It powers on with the ignition and shows your data instantly.

Will it fit your car?
The manufacturer’s listing says OBD mode works on gasoline vehicles from 2009 using the OBD2/EOBD protocol, and is not compatible with hybrids, diesels, pickup trucks, RVs or modified vehicles, nor with Renault, Peugeot, Citroën, Fiat, Jeep, Dodge, Hummer or the Honda Fit (Jazz). GPS mode (speed, direction, trip distance) works in any vehicle. Not sure? Run the HUD Compatibility Checker or test your gauge with the Speedometer Accuracy Calculator.
Best for
Drivers of 2009-or-newer gas cars who want engine data, with GPS mode as a fallback.
