Car HUD Headup Display MPH GPS Digital Speedometer with LED Large Font Display for Car Truck SUV Motorcycle(With Car Charge Adapter,MPH)

After a diff swap my speedo was reading very innacurately. Fitted this very quickly and found it simple to set up and install. Takes only a minute to set itself and readings are clear and steady. I can't measure the accuracy but it seems to fit in with what I would expect from the higher gearing I now have. I'm impressed.

I go this to have an accurate speedometer in my series 2a Land Rover. It was pretty easy to fit, very easy to see and seems accurate compared to my phone GPS and the speed warning signs on the way into town. Very pleased. A cheap and useful solution.

I was surprised at how easy this was to install just plug in the cable and go. It seems to register a couple of mph lower than my car. It seems reasonably responsive. Screen very clear.The biggest down is that it does not have any way of holding it in place, so as soon as I turned a corner it fell over.

Excellent for glancing at speed especially at 20 mph im London

I had bought a HUD from anotther vendor but the thing never worked properly every time I turned the engine off - when I turned it back on the display either woud not find a satellit or it woud be displaying Kilometres instead of MPH . Got so frustreted with it that I decided to choose another . This one only displays MPH ( if you want KPH you will have to chck that you have bought the right model )Took this one out of the box , Its a small size and the lead is long enough ( the last one , the lead ws too short) . Pugged it in and after a few seconds it found a satellite . Better still the next day when I went to use the vehicle again it worked as soon as the engin went on ( had to find the satellite which took a few seconds ) . It's a lovely clear display . Would definately recommend if all you want is a simple HUD .

Perfect accuracy when tested to other GPS Speedo on google maps, people who say it’s not accurate to their speedometer are mistaken as it’s actually the speedometer in their car which is set to show lightly higher than real GPS speed. Easy installation works right out of the box

Looks OK for the price but does not show true speeds. Around town shows same speed as car but 1mph slower on dual carriageway with half worn tires.

Ordered this as my campervan is on MPH, and our speeds in republic of Ireland are KMH. Unit arrived and works fine, good clear display but there is no way to change it from MPH to KMH as the advertisement alludes to so it’s of no real use to me. Would like to return or exchange it for one in KMH.
