How can we help you?

Frequently asked questions
Is the RoadGuard 5.5” HUD compatible with my car?

The RoadGuard 5.5” HUD is compatible with most OBD2/EUOBD cars (gasoline vehicles from 2004+ in the USA, 2008+ in other regions). However, it does not work with Dodge, Jeep, Mazda, Suzuki, all French and Italian cars, and some Kia/Hyundai models. Check your vehicle’s OBD2 port before purchasing.

Does the HUD work in bright sunlight or at night?

Yes! The auto-adjusting brightness feature ensures the display is visible in all lighting conditions. It also includes anti-glare nano-technology and a reflective film to enhance clarity, even under direct sunlight or at night.

Will the HUD drain my car battery?

No. The HUD automatically powers on/off with your engine to prevent battery drain. Additionally, it has a manual power button for extra control.

Is installation complicated?

Not at all! The RoadGuard 5.5” HUD is Plug & Play—just connect it to your OBD2 port, and it's ready to use. No tools, wiring, or technical knowledge required.

️Does the HUD support speed unit conversion (MPH/KMH)?

Yes, you can switch between MPH and KMH to match your preference and country’s speed limit system.

Can I customize the speed warning alerts?

Absolutely! The HUD allows you to set custom over-speed limits so you receive an alert when exceeding your chosen speed, helping you drive safely and avoid tickets.

Will the HUD display all vehicle data, or just speed?

The RoadGuard 5.5” HUD provides real-time monitoring of speed, RPM, water temperature, battery voltage, and mileage. It helps you track essential car health metrics while driving.

What if my car doesn’t support OBD2? Can I still use this HUD?

If your car doesn’t have an OBD2 port, this HUD may not function properly. However, some older vehicles may support HUDs with a GPS-based display alternative (not included). Check your vehicle’s compatibility before purchasing.
