AUTOOL OBD2 Car Windshield HUD Head Up Display with Speed Fatigue Warning RPM MPH Fuel Consumption for OBD II EOBD System Model Vehicle

Innovative and useful with a cool looking

I have this in my 2008 Ford Ranger truck and it works well, but if I had to change any of the programming, it would be difficult and I program automation controls for a living. If I had to change the speed offset I wouldn't know where to begin. The instructions are typical for a Chinese made product.Also the reflective film doesn't want to stay stuck to my windshield so I will live with the double reflection.Finally the fuel usage might be useful if it were in mpg, the display is only in metric so I gave up.

works great but a little tricky to set up.It took me about 30' to set up the parameters i needed

Probably one of my favorite Things I’ve brought for my car in a while. It makes it extremely convenient to see your speedometer, you never have to look down To see how fast you’re going. If you can’t see the projection on your windshield, it comes with some reflective tint as well. The quality on the tint material isn’t great so I suggest you get your own if that’s the case, but the projector itself is great. Highly recommend.

The unit is simple enough to install. Instructions are printed very smallSpeed indicator is disappointing. Indicates increasing higher than the OEM indicator as speed increases. Not really usable because this.Unit being plugged into the diagnostic plug interferes with OnStar being able analyze systems

The speed is off by 2-3 mph. Which doesn’t make sense when it’s plugged directly into the car. Kind of ridiculous.

Nice and bright. Looks really cool and is a very useful gadget.The speedometer is 2mph under my trucks actual speed and it will occasionally power itself off for no reason. You just have to tap the button on the side to wake it back up.The tachometer is accurate as well as temp and voltage readings. The fuel consumption is useless if you are American because it's only in L/100km.

Title says it all--it didn't work.
