wiiyii P6 OBD2 Head-Up Display HUD for Cars — Windshield Speedometer, GPS + Diagnostic Readouts

The wiiyii OBD2 Gauge Display Head Up Display P6 projects real-time speed, engine data and alerts onto your windshield or dashboard so you can keep your eyes on the road.

The P6 HUD combines OBD2 diagnostics and GPS positioning to show speed, fault codes and multiple vehicle parameters on a compact LCD panel. It installs without drilling using an adjustable bracket or windshield pad and automatically adjusts brightness and color to match ambient light, switching to red when a warning condition or speeding threshold appears. This product description explains how the P6 works, what it displays, and who will benefit most from adding a head-up display to their car.

How does the P6 HUD help me drive more safely?

The P6 keeps critical information in your line of sight so you don’t need to look down at the instrument cluster. By presenting speed and alerts at eye level, it reduces glance time away from the road and helps you respond faster to potential issues. The display also changes color to draw quick attention in abnormal situations.

• Projects speed and data onto the windshield or dashboard for at-a-glance viewing.
• Automatic brightness and color change (blue normal, red for alerts) for clearer visibility.
• Reduces distraction by minimizing the need to look away from the road.

What information can the wiiyii P6 show and how accurate is it?

The P6 supports both OBD2-sourced vehicle data and GPS speed, giving you richer and often more accurate readings than single-mode units. When connected to your car’s OBD port it can read over 100 types of engine and vehicle parameters as well as diagnostic trouble codes. If your vehicle does not support OBD2 protocols, the HUD will still provide speed and position using GPS.

• Dual-mode display: OBD2 data plus GPS speed by default for comprehensive readings.
• Reads diagnostic trouble codes and displays clear fault information.
• GPS-only operation available when OBD2 protocol is unsupported by the vehicle.

How easy is installation and daily use?

Installation is designed to be non-destructive and straightforward: either attach the adjustable bracket to the dashboard or stick the unit to the windshield with the supplied pad. The menu and interface offer multiple display styles and quick switching between 10 interface options so you can tailor the HUD to your preferences. Power comes via the vehicle’s OBD port, keeping wiring minimal and reversible.

• Two mounting methods: dashboard bracket or windshield adhesive pad.
• 10 selectable display interfaces and a clear LCD meter for customization.
• Plug-and-play power from the OBD port; simple setup without permanent modifications.

Will the P6 prevent speeding tickets or record driving data?

The P6 displays current speed prominently so you can better monitor your pace and avoid inadvertent overspeeding; however, it does not guarantee enforcement avoidance. It helps drivers stay aware of their speed on highways or local roads. The HUD also provides readable diagnostic codes which can help you decide when professional inspection is needed.

• Large numeric speed readout aids speed awareness to reduce unintentional violations.
• Alarm color change alerts you when speed or abnormal parameters are detected.
• Displays diagnostic codes to help identify issues for timely servicing.

Who is this for: The wiiyii P6 HUD is ideal for everyday commuters, long-distance drivers, rideshare and delivery professionals, and anyone who wants faster access to speed and engine information without looking away from the road. It suits vehicles with OBD2 support that want richer vehicle data, and also works as a GPS speedometer for older cars lacking full OBD2 protocol support. If you value safer, less-distracted driving and clearer on-road alerts, the P6 is a practical, non-invasive upgrade for your cockpit.
