KUOWEIHUD OBD2 Gauge Display Car Speedometer OBD2+GPS Dual Mode 3.5" IPS — Turbo Gauge & 6 Alerts

This slim dashboard gauge is built for gasoline cars from 2008–2025 and automatically switches between OBD2 and GPS to keep data visible if one source loses signal. The unit shows speed in either KM/H or MPH, includes a turbo readout, six configurable alerts, eight ambient colors, and five visual themes for fast readability on every drive.

How does the dual OBD2+GPS system keep speed readings reliable?

The KUOWEIHUD gauge prioritizes the vehicle computer via OBD2 but will instantly fall back to GPS when OBD data is unavailable, preserving continuous speed display. This prevents blank readings during ECU resets or momentary OBD interruptions.

• Automatic switch between OBD2 and GPS sources
• Works with gasoline engines from 2008–2025
• Selectable units: KM/H or MPH
• Maintains stable numeric and needle-style readouts

Can I customize the look and night visibility of the gauge?

Yes—the display offers five themes and eight ambient lighting colors to match interior styling or improve contrast at night. Themes change layout and color accents, while ambient lighting adds soft backlighting that enhances cabin aesthetics without glare.

• Five on-screen themes for different display priorities
• Eight ambient light colors to match vehicle interior

How easy is installation and daily use in a modern car?
