wiiyii P6 Head-up Display HUD for Cars — OBD2+GPS Speed, RPM & Coolant Temp, Auto-Dimming

wiiyii P6 HUD is a dual-mode OBD2+GPS head-up display that projects real-time speed, RPM, coolant temperature and alerts onto your windshield so you can monitor driving data without looking down.

Compact and easy to install, the wiiyii P6 combines onboard diagnostic (OBD2) input with GPS positioning to deliver accurate speed readings, engine data and customizable alarms. Choose between dashboard placement or windshield mounting, switch among multiple display themes, and rely on an auto-dimming screen that shifts from blue to red to warn you when thresholds are exceeded. The unit supports over 100 OBD data channels on compatible vehicles and falls back to GPS-only mode if the car lacks OBD2 protocol.

How does the P6 HUD help me stay focused while driving?

The P6 projects essential driving information directly into your line of sight so you don’t have to glance down at the dash. This reduces distraction and keeps eyes closer to the road while still showing precise numerical readouts.

• Projects speed, RPM and temperature onto windshield or reflector panel
• Adjustable bracket for optimal viewing angle
• Auto-dimming ambient color for day/night visibility
• Overspeed alarm for instant audible/visual warning

What data will the display show and how accurate is it?

The P6 displays vehicle speed, engine RPM, coolant temperature and check-engine code information when connected to an OBD2 port. With combined OBD2+GPS mode the device cross-references both sources for a fuller, more stable readout; GPS-only mode provides reliable speed when OBD2 isn’t available.

• Real-time speed from OBD2 and GPS fusion
• RPM and coolant temperature from OBD2 when supported
• Fault code reading and streaming live data
• Over 100 OBD parameters readable on compatible vehicles

How do I install and customize the P6 HUD?

Installation is non-destructive and straightforward: plug the cable into your car’s OBD2 port or use GPS-only operation. The P6 includes an adjustable bracket for dashboard placement and a stick-on option for windshield mounting, and it offers multiple display themes to suit driver preference.

• Two mounting methods: dashboard bracket or windshield adhesive
• Ten interface themes with quick switching
• Simple plug-and-play OBD2 connection or GPS-only start
• Brightness auto-adjusts to ambient light conditions

Will the P6 work with my car and is it safe to use?

Most modern cars with an OBD2 port are supported and will deliver the richest data set; if your vehicle lacks OBD2 the P6 still provides GPS-based speed. The HUD is designed to be a no-fuss add-on that keeps your focus forward rather than requiring dashboard glances.

• Compatible with most OBD2-equipped vehicles
• GPS fallback for non-OBD2 cars
• Non-invasive installation — no vehicle modification required
• Visual alarm color change to highlight unsafe conditions

Who is this for: Drivers who want clearer, faster access to speed, engine RPM and temperature without taking their eyes off the road will find the wiiyii P6 HUD useful. It fits commuters, highway drivers and anyone who prefers a modern heads-up readout over traditional dash instruments, especially those who want an easy, reversible install and alarm notifications for overspeed or abnormal readings.
