KONNWEI KW206 Car OBD2 HUD Digital Meter Gauge All in One Automotive Trip Computer Smart OBD Speedometer Water Temperature Fuel Pressure Tester for All 2003 and Newer Cars

This thing is awesome! I'm impressed with it so far. It works perfectly with a Crown Vic Interceptor. Some of the reviews I've seen where it malfunctions seem like they were made by people who tried to use this device in a car with an incompatible computer system. If you have an OBD II system at least up until 2011 (my car is a 2011), it should work The device is very accurate in terms of the speedometer and tach. The moment I hooked it up, I started getting readings I didn't know my car measured, such as air intake temperature, just to name one If you want the most out of your vehicle, I highly recommend this product. Just a heads up, initial hook will take a few minutes for the device to scan and determine what kind of sytem you have. And, at least for me, to enable sleep mode, I have to keep the key in the ignition until after the countdown finishes. Then the device will reboot with the logo. After that I can take the key out and it will do another countdown until going into sleep mode. Other cars or trucks may cause it to operate differently in this regard. Oh, and not to mention as a bonus, this device and scan for and clear out engine fault codes. The device also has very good build quality, and there's a slight weight to it, still lighter than a samsung galaxy phone, for example. EDIT: I've used the device for over a week now and it still works fine. It's accurate and timely. There's no lag in any of the readouts. For the sleep mode, I discovered you can just shut the car off and take the key out. It may do the countdown and reboot a few times, but it will eventually just go into sleep mode without you having to do anything else. Also, I did order an extra phone holder as the double-sided tape on the devices stand is not strong enough to hold up on a window for too long. This is a minor inconvenience compared to the overall quality of the product

Very nice and useful for removal of car error codes

Not sure but just run as my company manufacturer forgot a RPM option .

Bastante útil, complemento do computador de bordo.

I drive a 2008 Prius that lacks all the standard gauges. When driving, you have your speed and how much gas remains. You can't check your battery, charging inverter, RPM, temperature, or anything like that. By the time you get a warning light you have been caught off guard. This little device takes care of that. You are able to customize the layout of your display, choose what info is most relevant to you, and set alarms. Afraid your engine will overheat? You can set a warning alarm to make this device beep if something abnormal is happening with your car. This gives you ample time to find a place to pull over before damaging anything. It takes may functions of an OBDII scan tool and integrates them well. You can check your MPG, your fuel levels, ignition, and any other information provided by your car's computer. If you have an error code it will give you the code, any pending codes, and a readout from an internal database to let you know what is happening. I use this device every time I drive my car. The sticky tape is very secure and easy to mount to a convenient spot on the dash. The device comes with everything you need to use it. It is plug and play -- simply select what information you want to see full time with the press of a button. If you have a hybrid, make sure to enable hybrid mode or stop-start mode. This keeps the device on when your engine turns off at a stop light. Very convenient and great to use!
