OBD2 GPS Head Up Display P17 Digital Speedometer with Windshield Projector Overspeed Warning and On Board Computer

OBD2 and GPS Head Up Display with Digital Speedometer and Smart Vehicle Monitoring

Switching attention between the road and dashboard instruments can reduce driving focus.
Many vehicles provide limited real-time performance data in an easy-to-view format.
A dual-mode head up display combines OBD2 diagnostics and GPS positioning to deliver important driving information in one compact unit.

This smart head up display supports both OBD2 and GPS modes, providing real-time vehicle data, trip information, and configurable alerts while maintaining a clean and modern dashboard appearance.

Core Function

• Displays vehicle speed using OBD2 data or integrated GPS positioning
• Monitors engine RPM, coolant temperature, voltage, and other supported vehicle parameters
• Automatically switches between compatible operating modes for flexible use
• Provides intelligent alerts for overspeed, engine conditions, and extended driving sessions

Use Cases

• Daily commuting with real-time driving information
• Long-distance travel requiring continuous vehicle monitoring
• Drivers seeking additional performance and trip data beyond factory gauges
• Vehicles where GPS mode offers a standalone speed display independent of OBD compatibility

Key Features

• Dual OBD2 and GPS operating modes in one compact device
• Displays speed, RPM, coolant temperature, battery voltage, and fuel consumption in supported OBD mode
• GPS mode provides speed, altitude, compass, trip distance, and driving time information
• Supports overspeed, high coolant temperature, high RPM, low voltage, and fatigue driving reminders
• Acceleration and braking performance testing functions
• Modern hexagonal design with low-reflection matte housing
• Fast installation using a wired plug-and-play connection
• Designed for operation across a wide temperature range

Frequently Asked Questions

What is the difference between OBD2 mode and GPS mode?
OBD2 mode reads supported vehicle data directly from the diagnostic port, while GPS mode uses satellite positioning to display speed and travel information independently.

Will this work on every vehicle?
GPS mode is suitable for virtually all vehicles. OBD2 mode is designed for compatible gasoline vehicles that support OBD2 or EOBD protocols and may not function with many diesel vehicles, trucks, pickups, or electric vehicles.

Can I still use GPS functions while connected in OBD mode?
Yes. The updated system supports GPS-related information alongside compatible OBD functions.

Does it include overspeed and safety alerts?
Yes. The display supports overspeed warnings as well as other configurable alerts such as high coolant temperature, high RPM, low voltage, and fatigue driving reminders.

Is installation complicated?
No. The device is designed for quick plug-and-play installation and can typically be set up in just a few minutes on compatible vehicles.
