Disables the airbag system in my Toyota. Not worth my life
I like the tilt option but don’t like that only two data points are customizable and you can’t hide data or views I don’t want. This constantly is sending signals to several parts of the vehicle and thus it interrupts the airbag system. On my Toyota plugging this in disables my airbag. So it’s a risk to life to have this plugged in. Not worth my life

How did I get along without it?
This works great with my 2007 Mini Cooper, which inexplicably lacks a temperature gauge. This unit displays numerous parameters, to include coolant temperature. The unit turns off automatically when the car is shut off, resulting in no battery drain when the unit is left plugged into the OBD2 port. Turns on automatically when the car is started.The unit has many different displays you can use. And what’s better is that the unit will let you easily scan and reset engine error codes, eliminating the need to drag out my professional OBD2 code reader.Highly recommended!

Very cool, but
Super easy to use, very intuitive, cool led colors and displays – just like advertised. The only problem is it won’t work on every car or truck. There isn’t a list of compatible cars or I couldn’t find one. My 2004 toyota tacoma worked but caused the ABS warning light to flash whenever it was plugged in. So if it works on your car it is very nifty. If not, Amazon still taking free returns as of this date Oct 2023.

Works with hybrids!
This specific model that Im showing on the picture cost me less than 40 bucks and it works with hybrid vehicles, I have a 2025 toyota hybrid. It has a setting within the menu for the voltage that it says “com” and this is the setting for hybrid vehicles or the ones that shut off the engine when stopped. Really easy to read, nice animations, and very responsive. Tbh I love it. I bought it to see my RPMs and fuel efficiency and it works great. It is small enough to out it on my dashboard and the sticky pad works well. The length for the cable is good enough for you to tucked it inside the edges of the dash and routed where the OBD2 is.
