Kingneed Truck GPS Speedometer 6.2 inch Extend Digital Display Vehicle Odometer Trip Meter Course Overspeed Alarm MPH/KMH

This is perfect for my 2014 Subaru Foreester it doesn’t have the speed warning feature and I drive through major construction to get to work! I can keep my eyes on the work zone area the traffic and my speed limit so much easier. I highly recommend this. So easy to use!

I’ve had it for around a year now and it’s great for my project build. I go up to the mountain to drive around and it still works great where my phone doesn’t get service. Easy to install and easy to use. Recommend highly for a project build and will buy another one

The purpose of this device is to provide an accurate speed using GPS. Quite simply, it fails its main objective. It consistently reads about 3% too slow. I've measured it again many other GPS units, dash speedometer, highway radar signs. I've tried this in different weather, different geographies, etc. Every single time, this unit reports about 3% too slow. It obviously has a calculation error embedded in the unit.

Works with anything

Alright so I tried a couple different brands out this one had the easiest set up, and actually worked. The display is bright enough no matter what anyone says, I am in central Florida and tested the speedometer on my ‘23 t bucket hot rod maximum sun exposure and could still easily make out the numbers. It was pretty accurate the downsides are the lag, if you put the petal down your going to be around 8 to 10 mph faster than what it says while accelerating same with had braking it will be just as behind, if you know your engine sound and the feel of it accelerating then with this speedometer you can tell when to let off the petal. I took a star away because the ball joint on the mounting arm is loose as hell and it doesn’t tighten up, either way still a good purchase.

At low speed around 30 MPH is accurate above that speed will start to be off 2 to 3 MPH faster than the speed you are going.

For me it worked great right out of the box. And I didn't have to calibrate -- it was right in line with the car speed and a speedo app on my phone. It does take a bit to find all the satellites though. Would be nice if it came with a USB cord too.

everything was great

I really happy about this it really helping me

My dad is 72 and has started struggling to read the dash in a timely manor. He said it takes him too long to find, then focus on the odometer, and he's worried he'll become a dangerous driver really soon. So I found this dash odometer. You get exactly what you pay for, and we knew that going in. Dad made it a bristle board box shade, so it would glow better in the sun. He then bought strong velcro to attach the base to the dash, and another small piece on the unit to attach to the window. The supplied base was obviously going to be a big piece of useless rubbish, and boy was it ever. Saying that, dad loves it. He only has the odometer reading setup, so there are no other numbers visible on the side. He said it works and makes him a much safer driver again. So if you're willing to put a few bucks into this unit upon arrival, it's a great aid for an older driver. It keeps their eyes above the dash.

Pas précis. Pas de 10 iemes de km et quand on bouge la plug dans la prise on perds les données Je veut quelque chose de plus précis
