Review on 🚗 Autool X50 Plus Car OBD HUD Multi-Function Digital Meter Alarm Speed Water Temp Head Up Display for OBD Driving Computer – Supports 12V OBDII Diesel Vehicles by Michael Wilder

This product works well, but you may need to make some changes to the menu after the initial installation. By default the system uses SI units (km/L/degrees Celsius), you can use imperial units or a combination of both (US/mi/h/mpg/degrees F), you just need to set up the device. - There are a few custom features I didn't know about before purchasing such as: B. Color options. There is 1 button, you press the button to confirm or return (short press or long press has different effects), the button is a side scroll switch that allows you to switch between menu options (up/down), main display options (speed , speed, etc.) and the selection of a numerical value.
