MAIMEIMI OBD2 Digital Head-Up Display HUD for Sedans — Black, Dual OBD2+GPS Speedometer with RPM & Temp Alerts

Keep your eyes on the road with a compact HUD designed for most 2008-and-newer sedans. This MAIMEIMI unit combines OBD2 vehicle data and independent GPS speed readings so you can monitor speed, engine RPM, battery voltage, fuel consumption and temperature metrics without looking down at the gauge cluster. Auto-dimming and multiple installation options make it suited for different windshield angles and driving conditions.

How does the dual OBD2 and GPS system improve accuracy?

The MAIMEIMI HUD reads live engine parameters via the OBD2 interface on compatible cars and uses a GPS sensor for precise speed when OBD data is unavailable. GPS mode ensures consistent speed readings on non-OBD vehicles, while OBD2 mode exposes deeper engine stats like RPM and some temperature readings.

• OBD2 mode: real-time engine RPM, some engine temps, and diagnostic metrics (for OBDII/EOBD-compliant cars).
• GPS mode: accurate vehicle speed and location-based speed readings for any compatible car.
• Automatic switch and calibration options for smooth transitions between modes.

What alarms and safety features will I get while driving?

The unit includes customizable warnings so you can be alerted without glancing away from the road. Set thresholds for overspeed, excessive RPM, high coolant temperature and low battery voltage; each alarm triggers a visible and audible prompt.

• Overspeed alarm to prevent unintentional speeding.
• High-RPM and overheating alerts to protect engine health awareness.
• Low-voltage alert to warn of battery or charging issues.

How easy is installation and day/night visibility?

Installation takes minutes and requires no permanent modifications: choose between a strap mount to the A-pillar or a non-slip pad on the dashboard. The HUD has an ambient light sensor that auto-dims the display, maintaining clear, anti-glare readouts in bright daylight and low-light conditions.

• Two mounting options: adjustable strap for A-pillar or non-slip pad for dash placement.
• Rotate display 90° for angle calibration depending on mount choice.
• Auto-dimming screen with anti-glare rendering for safer nighttime and daytime use.

Which vehicles are compatible and what are the exceptions?

This HUD works with most sedans made from 2008 onward that support OBDII/EOBD standards and with virtually any car in GPS mode. However, OBD functionality does not support certain manufacturers, models, or powertrain types listed in the manual, and it is not intended for trucks, RVs, or heavily modified ECUs.

• Compatible: most 2008+ sedans with OBDII/EOBD support and GPS-capable vehicles.
• Not compatible: many pre-2008 international models and certain brands (see manual list).
• Not suitable for hybrid/diesel-specific systems, some luxury models, trucks, RVs, or modified ECUs.

Who is this for: Drivers who want continuous, glance-free access to critical driving data—commuters, long-distance drivers and enthusiasts—will appreciate MAIMEIMI's HUD. It’s aimed at owners of compatible 2008-and-newer sedans who value situational awareness and want an easy, non-invasive upgrade to their cockpit that provides speed, engine readouts and configurable safety alerts without redesigning the dashboard.
