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 Jacob Schmidt

This works great on my 99 Dodge Dakota. EXCEPT: 1. AVG and Current MPG are not very accurate (which is to be expected given that this device does mpg calculations instead of getting them straight from the computer as my truck has no mpg info at all)2. The larger main display shows the correct imperial measurements (miles, Fahrenheit, gallons, etc.) BUT the two smaller displays, which can show several different measurements, do not show the correct measurements and there is no way to change this I can find. These two negatives are the only reason I gave 3 stars. Otherwise, it's a very neat little device for a "dumb" car. I haven't had any trouble codes since I had it so I don't know if the OBD code reader and reset function works but I assume it does. Also, the device was smaller than I thought was good because I thought it would take up too much space on my dash.
