AZIJYV M11 Heads-Up Display for Cars — 3.5" OBD+GPS HUD with Speed, Water Temp & Overspeed Alarm

The AZIJYV M11 is a compact 3.5-inch head-up display that projects real-time speed, water temperature, mileage and multiple alarms onto your windshield using OBD or GPS data.

The M11 HUD combines OBD and GPS inputs to give drivers a clear, reflected readout of essential vehicle parameters without forcing eyes off the road. With an adaptive light sensor, overspeed and system alarms, and simple plug-and-play installation, it’s designed to improve situational awareness for most gasoline vehicles (OBD-compatible) and all vehicles via GPS mode.

How does the M11 show speed and other driving data?

The unit uses two data sources: OBD for direct vehicle bus information and GPS for satellite-derived speed and distance. When connected to a compatible OBD2 port it reads vehicle speed, water temperature, voltage, trip mileage and fault codes. If OBD isn’t available or compatible, the GPS mode supplies accurate speed, satellite count and single-trip distance.

• Displays current speed as a numeric readout and progress bar.
• Shows water temperature, battery voltage and trip mileage.
• Switches automatically between OBD and GPS inputs as selected.
• GPS works with any vehicle; OBD requires compatible OBD2/EU-OBD protocol.

What alarms and alerts will the HUD give me?

The M11 issues multiple audible and visual warnings so you can respond quickly while staying focused on driving. Alerts include overspeed, high water temperature, low voltage, fatigue-driving reminders and detected fault codes when in OBD mode. Each alarm is configurable so you can set thresholds that match your preferences and vehicle condition.

• Overspeed alarm with adjustable threshold.
• Water temperature and low-voltage warnings to detect potential issues early.
• Fatigue-driving reminder to encourage breaks on long trips.
• Fault-code notification when connected via compatible OBD systems.

How easy is installation and operation?

Installation is straightforward: plug the HUD into the car using the included USB cable and choose OBD or GPS mode. The device powers on with the engine and overlays data on the windshield using its reflective flat screen. An adaptive light sensor reduces ghosting and keeps the display readable in different lighting conditions without manual adjustment.

• Plug-and-play connection via USB; OBD cable for OBD mode supplied as needed.
• Adaptive brightness reduces blur and improves daytime/night readability.
• Compact 3.5-inch flat display mounts on the dash and reflects data on the glass.
• Quick mode switching between GPS and OBD depending on vehicle compatibility.

Who is this for? The AZIJYV M11 HUD suits drivers who want a low-cost, non-intrusive way to monitor speed and basic engine parameters without removing attention from the road. It works best for gasoline cars with OBD2/EU-OBD protocol (typically post-2009 models) when you want direct vehicle data, and for any vehicle when using GPS mode. Note: OBD mode is not compatible with certain brands and vehicle types (diesel, hybrids, many older or manufacturer-specific systems), so verify compatibility before relying on OBD features.

Compatibility reminder: OBD functions require standard OBD2/EU-OBD protocols and are not supported for some manufacturers and vehicle types such as Renault, Peugeot, Citroen, Fiat, Jeep, Dodge, certain pickups, RVs, diesel engines, hybrids and heavily modified vehicles. When in doubt, choose GPS mode or consult AZIJYV support prior to purchase.
