Shkalacar Car Digital GPS Speedometer Car HUD Heads Up Display with Speed, Mph/Kmh，USB Plug and Play for All Car

Easy to use and works great

The media could not be loaded.  Tried to fix my speedometer by cleaning the contacts and resoldering the joints but it still get stuck every now in then and since my car is 32 year old and i didn't want to falsify the mileage on my car. So i got this as a solution and it works great just mount it, plug it in to a usb power port, and wait around 30sec for it to calibrate then just drive.

This is just what I was looking for. The dash on my 2018 jeep wrangler. JK is very dim and hard to read even in the daytime. This is a shortcoming of that particular generation of Jeep so anyway I put this in and it was easy to install and I absolutely love it, the only reason I didn’t give it five stars were first of all. It is super bright and actually too bright and nighttime so I had to relocate it from on top of the dash to the instrument cluster (see picture). So it would be nice if they included dimming control on this unit. The other minor issue is that it takes almost a full minute for the GPS to start registering tracking and giving you a speed so sometimes I’m almost a mile away from home before I can read the Speed. But both those things are such minor issues to me that I still love this item.

Works great

The velocimeter works very well. Compared to the GPS on my phone, the velocimeter is very accurate. As it says in the description, it only takes 30 seconds to obtain the GPS signal. For me, the size is perfect. I can't give it a higher rating for two reasons. The first reason is that it's very bright at night and the brightness can't be adjusted. The second reason is that it doesn't have USB C. Now I have to have 2 cables in my car, one for the phone and one for the velocimeter.

Funciona muy bien me gusto

It works but it wouldn’t fit where I needed it. That’s not the company’s fault. So 5 stars even though I returned it

This being one of the cheapest, and most basic GPS based USB powered Speedometer there is.No buttons, not settings, just plug it in and it works.(make sure you buy the correct model, either the MPH or the km/h)It is BRIGHT, no way to dim. ( I have the white model)It is great in the bright sun, but way too bright at night.Some "LED dimmer stickers" or limo window tint works well to dim this.It is accurate at lower speeds, 35mph and under.Highway speeds, it is 3 -5 MPH high.Other similar devices to this, have a way to adjust the accuracy, not so on this one.But, for me, since it is so cheap, it is "good enough" for me to glance at while driving, since i can not see my car's normal spedo, due to the position i have the steering wheel.It uses USB Mini connection and cable. (not micro or C)It will vary how long it will take to lock on to satellites, but most of the time, it only took maybe 10 secs or less.

Pros:- Awesome speedometer for its price.- Plug and play.- I would say around 2-3 km +- discrepancy from my manual speedometer.Cons:- 20-30 second wait from when you start the car until it finishes connecting to a satellite.- loses connection in tunnels.

Dauert ungefähr 30 - 40 Sekunden bis das Teil betriebsbereit ist .

J'ai acheté ce compteur parce que mon Duster a juste un compteur à aiguille et je devais détacher le regard de la route pour contrôler ma vitesse. Je l'ai collé avec l'adhésif sur le dessus du tableau de bord. Il est branché à la batterie via l'allume cigare et une connectique (allume cigare / USB) que j'ai trouvé pour qqs euros. Je démarre et il m'affiche la vitesse dans les 10 secondes qui suivent. Il fait très bien le job. Je suis contente de mon achat.

I have a car speedo that is in mph but I live in Canada speeds are posted in kphThis unit has saved me more than one ticket so far

La description porte à confusion alors qu'il ne fait que compteur mais vraiment très lisible , le vendeur est très à l'écoute de ses clients, allez sur sa boutique il a vraiment des produits très sympa....
