AMROOLOOHead up Display for Cars, Rotatable Screen In-car Instrument, Displaying Driving Data, GPS Speedometer, OBD Car Head-up Display, Suitable for All Cars, black

This was purchased to not only establish how inaccurate the vehicles own speedometer was, but to also see at a glance, what actual speed I was doing to avoid fines and points from fixed and mobile cameras in 30 mph roads.After using for several months since purchase, the following information can be revealed.1. It's really easy to fit....plugs into the onboard diagnostic port (OBD II). The only tools you will need are plastic trim tools to feed the cable neatly behind plastic trim. The until can be placed in various positions to suit the vehicle as it changes display angle like a phone.2. The speedo of my vehicle is consistently 3mph lower than the GPS speedo. This is built into the vehicle to avoid actually speeding.3. Gives other information like distance/battery voltage/mph/time travelling etc. The display can be set to provide the information relevant to your needs.Then unit has never failed to receive data from satellites and works as it should consistently.Would I recommend, absolutely. What price do you put on knowing your actual speed in a camera zone; nobody want a fine etc particularly when you have fixed, mobile, community radar, average speed cameras etc everywhere.

This was bought to go on the passenger side of my driving school car as the car speedo was difficult to see, extremely easy to instal and set up,would recommend it as it can be positioned in so many different positions.

Use an iPhone app instead, this is rubbish

Does the job. Buttons very fragile. But does a decent job.

No complaints and it’s does what I want it to do.

The device itself seems to work fine, but it's materials are rather cheap and flimsy.A heads up for anyone in the UK or other countries with LHT and want to fit this to their A-pillar... Unlike the picture, it will not sit neatly on the right a-pillar, so clearly the photo is just a mirror of the left.Due to its flat bottom and the rather thick velcro pad it comes with, it looks freaking awful sitting on the dash itself too.I'll either have to return it or gift it to someone who has the flattest dash ever!

help requested, doesn't display ECT Engine Coolant temperature, the whole reason I bought it,really wanted this to work seems to be missing a lot of monitoring values - is there anything I can do to make it work?only battery voltage, GPS direction seems to work

The media could not be loaded. Bought this for my newly imported 2008 skyline to have mph speed. Tested it on my 2017 Volvo and it worked soso, occasionally device said: no obd2 support. In the skyline when on OBD it only shows battery voltage and when on gps mode it sometimes goes to menu and sometimes goes blank. Sometimes you can access menu hitting OK button, etc. Hit and miss performance. Will be returned
