AMROOLOO specializes in aftermarket automotive head-up displays (HUDs) and digital speedometers, providing real-time driving data via OBD2 and GPS connections.
AMROOLOO is a manufacturer of automotive electronics, specifically focusing on aftermarket Head-Up Displays (HUDs) and smart digital gauges. Their products are designed to enhance driving safety by projecting critical vehicle data—such as speed, engine RPM, water temperature, and voltage—directly into the driver's line of sight or onto a dedicated reflective screen.
Compatible with a wide range of vehicles through OBD2 ports or GPS USB connections, AMROOLOO devices offer features like speeding alarms, fatigue driving reminders, and automatic brightness adjustment. These easy-to-install gadgets help modernize dashboards and ensure drivers can monitor vehicle performance without monitoring away from the road.

Car manufacturers often calibrate dashboards to show a speed 5-7% higher than actual satellite speed. You can fine-tune the AMROOLOO HUD speed in the settings menu (e.g., adjusting the value from 107 to 102) to sync it with your dashboard.
If the device stays on after the engine stops, enter the settings menu and adjust the 'Sleep Voltage' to 13.2V or 13.6V. Alternatively, use the USB cable connection (GPS mode) instead of the OBD cable.
OBD2 mode typically works with gasoline vehicles produced after 2008. For older cars, hybrids, or vehicles with compatibility issues, use the GPS mode connected via USB.
In GPS mode, the device requires a robust satellite signal. Speed may not display in tunnels, underground parking, or areas with heavy obstruction. Drive to an open road to acquire a signal.
Navigate to the settings menu, find the 'Factory Reset' option, set the value to 1, and long-press the control button to save and exit.
