Automotive HD Speed Projector Display with 3.5 Inch LED Screen and OBD Interface

This automotive head-up display is designed to show speed and vehicle data on a 3.5-inch LED screen with HD resolution. It connects through the OBD interface, which is the standard diagnostic port found in most modern vehicles, and it is operated by manual control. The unit measures 90 x 54 x 12 mm, so it takes up minimal dashboard space. Its ABS and PC housing is typical of automotive interior plastics, offering a practical balance of rigidity and resistance to everyday cabin conditions. The package includes one monitor. No additional cables, mounting hardware, or compatibility list is stated in the source data, so buyers should check their vehicle's OBD port before purchase.

Features and Construction

The display is built around a 3.5-inch LED screen and an ABS plus PC housing. These details define the physical product, while the OBD interface and manual control describe how it connects and operates. The following sections cover the material and build, then the size and practical fit.

Material and Build

The housing uses ABS and PC. ABS is a widely used thermoplastic in car interiors because it is rigid and can be moulded into compact shapes. PC, or polycarbonate, is often blended with ABS to add toughness and some heat resistance. Together they form a housing suitable for a small dashboard device. The screen type is LED, and the resolution is HD. No further construction details, such as mounting method or cable length, are provided in the source text.

Size and Practical Fit

The appearance size is 90 x 54 x 12 mm, and the screen measures 3.5 inches. These dimensions make the unit small enough to sit on a dashboard or console area without blocking much of the windscreen. The slim 12 mm profile helps it stay discreet. Because the source does not state a mounting bracket or adhesive type, buyers should consider how they will position it in their vehicle. The compact footprint is the main practical fit advantage supported by the data.

Uses and Placement

This head-up display is intended for use in vehicles with an OBD interface. It can serve as an on-board display for speed and other data the vehicle provides through that port. Placement depends on the dashboard layout and the driver's line of sight. The sections below outline event or professional use and everyday home use, though the primary context is in-car.

Event or Professional Use

For driving events, track days, or professional driving where speed readouts need to be visible without looking down at the instrument cluster, a compact HUD can be useful. The 3.5-inch LED screen and HD resolution are intended to make numbers legible. The OBD connection provides data directly from the vehicle. However, the source does not specify which vehicle models or protocols are supported, so professional users should verify compatibility before relying on it in a timed or regulated setting.

Everyday Home Use

In everyday driving, the display can show speed and basic vehicle data on the dashboard. The manual control allows the driver or passenger to adjust settings when the car is safely parked. The 90 x 54 x 12 mm size means it can be placed in a convenient spot without dominating the cabin. Since no smartphone app or wireless connection is mentioned, all data comes through the OBD interface. This keeps the setup simple but dependent on a compatible OBD port.

Benefits and Buying Value

The main buying value lies in the combination of a 3.5-inch HD LED screen, OBD interface power, and a compact ABS plus PC housing. These are concrete features that support a straightforward head-up display function. The sections below cover reuse and low maintenance, then explain why this product may suit certain buyers.

Reuse and Low Maintenance

Because the unit is powered through the OBD interface, there are no separate batteries to replace, based on the stated power supply mode. The ABS and PC housing can be cleaned with a soft dry cloth, which is a low-risk maintenance approach for these materials. The screen is LED, so there are no user-serviceable parts mentioned in the source. This means maintenance is limited to keeping the screen and housing free of dust. No lifespan or service interval is claimed.

Why Choose This Product

This head-up display may appeal to drivers who want a small, manual-control unit with a 3.5-inch LED screen and OBD connectivity. Its 90 x 54 x 12 mm size makes it easy to fit in many vehicles, and the ABS plus PC housing is consistent with automotive interior materials. The package includes one monitor. Since the source does not provide price, savings, or comparison data, the value should be judged on the stated specifications and compatibility with your vehicle's OBD port.
