Multi-function OBD2+GPS Car HUD Head Up Display | A-Pillar Turbo Gauge

Get real-time vehicle data without taking your eyes off the road. This multi-function HUD display connects to your car's OBD2 port and GPS to show speed, RPM, turbo pressure, water temperature, oil temperature, and more. It installs on your A-pillar trim or dashboard for a clean, professional look.

This on-board computer works with both OBD2 and GPS systems. The OBD mode pulls data directly from your car's computer, while the GPS mode works independently for vehicles without OBD2 support. The 240x240 high-definition screen rotates up to 270 degrees, so you can position it exactly where you need it.

Track up to 20 different parameters including vehicle speed, fuel consumption, intake pressure, air-fuel ratio, and driving time. The display refreshes at up to 10 Hz for smooth, lag-free readings. Set custom alarms for overspeed, water temperature, and voltage to stay informed of any issues.

This HUD supports both metric and imperial units. When you switch speed to MPH, the system automatically converts water temperature to Fahrenheit, distance to miles, and fuel consumption to MPG. Eight different display screens let you choose the layout that works best for your driving style.

Key Features and Benefits

- OBD2 and GPS dual system that provides accurate data in both modes

• 270-degree rotatable screen that lets you adjust the viewing angle for any mounting position

• 240x240 high-definition display that delivers clear, easy-to-read information

• 10 Hz refresh rate that shows real-time data without stutter or delay

• Adjustable turbo pressure units (PSI, 100kPa, bar) that match your preference

• Automatic unit conversion that switches to imperial when you select MPH

• 8 selectable display screens that give you flexible data layouts

• Built-in alarms for overspeed, water temperature, and voltage that keep you informed

Who Is This For

- Car enthusiasts who want real-time engine data like turbo pressure and RPM

• Drivers who prefer a head-up display mounted on the A-pillar for better visibility

• Vehicle owners who need both OBD2 and GPS speedometer options

• Anyone who wants to monitor fuel consumption, water temperature, and voltage while driving

Usage Scenario

Mark drives a 2015 sedan with a turbocharged engine. He wanted to keep an eye on his boost pressure and water temperature during long highway trips. He installed this HUD on his A-pillar trim using the included strap. Now he can see his RPM, turbo value, and coolant temperature at a glance without looking down at the dashboard. The overspeed alarm helps him stay within speed limits, and the voltage reading gives him early warning if his battery is weak.

Micro Comparison

Many basic HUDs only show speed and RPM from the OBD2 port. This model adds GPS functionality so you still get readings even if your car does not support OBD2 mode. The 270-degree rotating screen and A-pillar mounting option give you more placement flexibility than standard dashboard units. The 10 Hz refresh rate also provides smoother data updates compared to lower-refresh displays.

Questions and Answers

Question: Will this HUD work with my 2018 diesel car?

Answer: It works with most cars that have a standard OBD2 port, including many diesel models. Check if your car has OBD2 support. If not, the GPS mode will still provide speed and other basic data.

Question: Can I mount this on the dashboard instead of the A-pillar?

Answer: Yes, you can lay it flat on the dashboard or secure it to the A-pillar trim using the included fixing strap. Both mounting options are supported.

Question: Does the GPS mode require an internet connection?

Answer: No, the GPS mode uses satellite signals only. It does not need any internet or cellular connection to display speed, altitude, direction, and other GPS data.

Question: What does the turbo pressure display show?

Answer: It shows the turbo boost pressure from your car's engine control unit. You can switch between PSI, 100kPa, and bar units. The value only works correctly if your car has a factory turbocharger.

Question: How do I set the overspeed alarm?

Answer: You can set the overspeed alarm through the device menu. When your speed exceeds the set limit, the display will alert you visually. The same applies to water temperature and voltage alarms.
