AMROOLOO Dual System Car Head-up Display, Showing Multiple Functions, GPS Speedometer, OBD In-car Dashboard, with Multiple Prompt Functions

Installation was easy. Just plug in the OBD2 connector, and go. Accuracy is good - I drove around comparing with the car speedometer. Manual calibration can be done but in my case it was not necessary. There are several display types to choose from, and each one has some level of configurability.Clear to see both in daylight and at night. I rarely need to look down to the car speedometer nowadays, which makes driving safer.Only 1 slight defect is that during very sunny days, in the direct sunlight for a long time, the screen is no longer reflective. After some minutes and it cools down, reflection is back and the it is back to normal.

impressed works straight out the box helps to keep your eyes on the road

It’s ok it’s not the best on obd2 the speed is 3 miles an hour slower the my car speedo and the customisation is finicky overall it’s ok

Works fine as a rule, except it keeps shutting down for no apparent reason randomly, the either you have to restart or sometimes it starts itself but you lose your journey time and distance

Provides useful information.Easy to install.

This product is not compatible with my car. So please state what cars this item is not compatible with next time.

So easy to plug into your OBD, powers up and running. Spot on with the speed and everything else.

Product not reading error codes... Screen is much bigger than numbers shown on it (1/3 on each side not used). As unit is small, you still need to look down to see your speed... At evening you can see more than one reflection, so a little bit annoying...If I will find the way how to put it diagonally so that projector not cover part of the screen, then possibly will keep it as speed reading is correct and it is switching automatically off when car is not used. But there is more Cons then Pros...
