Review on Autool X60 Car OBD Head-Up Display (HUD): Multi-Function Digital Meter with Speed Alarm & Water-Temp Gauge for 12V OBD-II Standard Vehicles by Charley Prz

What the heck OBD sensor for under $40 I might take a chance. Also, I keep losing my bluetooth to reset the stupid evap code on my JK jeep and I can just leave that here. Connected, synced, data read, codes cleared, data displayed. I don't know why people have problems lol. Yes the instructions are in English and they don't tell you some things like the top button which also toggles left/right so you can change what you see. The mounting base is cheap and flexible, but can easily be made more ribbed. Every once in a while it "scrolls left" and changes what I'm seeing to the main display, whether it's speed again or temperature or whatever. was bright enough to see during the day and not be blind at night, most likely there is a setting you won't find out about but LOL worth the money. If you are using a standalone ECU, buy a pair and a splitter and use them to read general data as well.
