3.5-inch OBD2 HUD for daily driving

The LUOM KW206 is a 3.5-inch digital head-up display that connects through the OBD2 port on any compliant gasoline or diesel vehicle. It shows speed, coolant temperature, battery voltage and fuel consumption on a single screen so the driver keeps eyes on the road. The unit also reads and clears diagnostic trouble codes. Power comes from the vehicle 12 V system with a 15 A maximum current rating.

Drivers who want live data without a phone mount

Suits motorists who prefer a dedicated gauge cluster for speed, temperature, voltage and economy figures plus the ability to erase check-engine codes on the spot. Not for technicians who need bi-directional control, graphing data streams or coverage of manufacturer-specific modules beyond the standard OBDII set. Buyers who require a built-in GPS speed source independent of the ECU should look elsewhere.

OBDII full-protocol support with 34 live parameters

The scanner implements every OBDII protocol including J1850 dual-protocol and ATTPS commands, delivering 34 real-time data sets such as fuel level, engine load, oxygen sensor readings B1S1 and B2S1, and instantaneous fuel consumption. A one-click readiness key gives quick emissions-test status. The 3.5-inch LCD switches between metric and imperial units per parameter.

Questions about this item

How do I install the KW206 and what is the step most people miss?

Plug the OBD2 cable into the vehicle's 16-pin port, then connect the other end to the KW206. The step most people miss is turning the ignition to the ON position before the device powers up and begins scanning for protocols.

What maintenance or replacement will the KW206 need later?

The unit runs on AAA batteries, so you will need to replace them when the 3.5in LCD dims or the device fails to power on. No other user-serviceable parts are inside.

What limit shows up first during sustained use of the KW206?

The specified operating noise range of -10 to +56 dB and the 15 A maximum input current are the first electrical and acoustic limits you will encounter under continuous operation.
