A: In OBD2 mode, it is compatible with European vehicles from 2005 onward and vehicles from all other regions from 2008 onward. If your car does not support OBD2 (e.g. older models, hybrids, EVs, or RVs), simply use GPS mode — GPS mode works with every vehicle regardless of make, model, or year.

Q: Can OBD2 and GPS data be shown at the same time?

A: Yes! This HUD uniquely allows both OBD2 and GPS data to be displayed on the same interface simultaneously, so you get rich engine data alongside GPS metrics like altitude, satellite count, and driving direction all in one view.

Q: How do I mount the HUD on my dashboard?

A: The package includes an adjustable bracket that tilts up/down and slides forward/backward so you can position the screen perfectly for your eye line. Mounting tape and a crowbar tool for neat cable routing are included, making installation straightforward without any permanent modifications to your vehicle.

Q: What alarms does the HUD support?

A: In OBD2 mode, the HUD will alert you for overspeed, RPM overspeed, excessive water temperature, low voltage, and engine fault codes. In GPS mode, it alerts for overspeed and low voltage. The LED ambient lighting also flashes red as a visual alarm cue.
