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

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

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

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

Overall, great - quite accurate, more the speed rather than revs, some degree of customisation, but please note: cannot really see the readings with polarised sunglasses (I use them...)

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.

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.

Do not buy, states its compatible with all cars but its said on screen after setting up it’s not compatible with my car. When I come to returning the device, you can’t even get it in the box. Not a good product would not buy!
