3.5in OBD2 HUD for real-time vehicle data

The LUOM KW206 connects to any OBDII-enabled petrol or diesel vehicle and projects live engine parameters onto a 3.5in digital LCD. It combines speedometer, tachometer, coolant temperature, fuel consumption and voltage readouts in a single head-up display. The unit also performs 0-100 km/h acceleration timing and reads or clears diagnostic trouble codes.

Verify 12 V system and OBDII port access

The device draws power from a 12 V vehicle system and requires a standard OBDII diagnostic connector. Confirm the car was manufactured with OBDII compliance before fitting. The package includes an OBD2 cable and a USB cable for connection and updates.

Mounts on dash; frees cluster visibility

The compact 5.35 x 3.46 x 2.2 in housing sits on the dashboard and runs from the OBDII port without permanent wiring. It displays 34 selectable data streams including fuel level, engine load and oxygen sensor readings. Audible and visual alerts for speed, temperature and voltage reduce the need to glance at the factory instrument cluster.
