GPS Speedometer Odometer 125MPH Mileage Adjustable Overspeed Alarm for Boat Car Truck Motorcycle 85mm

Works great very accurate 5000 miles so far

First one had issue,they quickly sent me another I was glad they gave me plenty of time to return defective one so I didn't have to remove wiring installed from first one.Plugged it in worked good except if you're somewhere there's poor signal you have to wait for one on startup or no speedo,but I've never lost signal when driving so far.Warning buzzer doesn't work have to try it again

Ok, the instructions aren't awesome, but they are good enough to get the job done. I installed this in my vintage RV that had a bad speedo, and it didn't take me long to get wired into the existing wiring and set up with the old mileage shown on the RV odometer. I like that this particular model allows me to eliminate the extra lights for the turn signals and high beams, which will be nice when I make other improvements to the instrument cluster. I also chose this one because 60mph is straight up. an RV doesn't need a 125mph speedometer, but having the needle straight up makes it easier to read in my case.

Great product. I had no trouble installing this and once setup it is very dependable. Just to clarify: you can input your old speedometer's mileage reading and it will start the odometer from that input number. It also has a trip odometer that can be accessed and reset from the included, optional, external button. The wiring for the external button is one wire goes to the clearly marked wire on the speedometer harness, the other post on the button goes to ground. Day to day, I don't think you would know my vehicle's speedometer is GPS, the smoothing algorithm is excellent! The reason my review is 4 star instead of 5 is for the instructions. They're like putting together a board puzzle, seller should re write them in actual English. I would recommend this product and I would buy it again. I asked the seller two questions and they replied quickly.

worked for a few days. Then the speedometer was very inaccurate by about 30 mph. Also the wiring harness had 2 missing wires. So I ordered a replacement and sending this one back.

I was a bit worried about it after I ordered it, wondering if it would work properly and not be erratic. Boy was I pleasantly surprised after I got it hooked up on my motorcycle. This thing is absolutely accurate and there is no JUMPING of the needle. It's as smooth working as the speedometer in my sixty thousand dollar truck. Also I chose this speedometer because it is graduated in "fives" with no 3.3 mph (or something like that) marks in between, which is ridiculous. With this speedometer each mark is five mph like it should be. It looks cool on my bike and if it weren't for me being old and technologically challenged I would show a picture of it on my bike. The left turn, right turn and high beam lights work well although the left and right turn indicators need to be brighter because they're hard to see on a sunny day. The backlight glows nicely; I chose red. The wiring directions are not the best in the world but I figured it out. Do I recommend it? Yes, it's a great product.

I hooked this up to a battery and took it out for a test comparison in my 2016 Focus. It looked to be very close to the same mph readings as my dash speedo. My only criticism would be the lighting design. Only yellow or red back lighting, nothing more natural to choose. And the lighting isn't uniform across the face of the gauge. Overall, I rate it a B+. Good quality.

It has become difficult to get replacement speedometers for Ural motorcycle. This fits the factory dash but obviously requires rewiring the original connector and installing external lights for some indicators.

This is the first of two I had bought for a kit car. This first one failed before I could even get the car out the garage, not sure what the problem was, but only backlight worked. Replacement seems more reliable, though it's frustrating as you have to wait over a week for delivery.

Finnally got to take the truck for a test drive last week.ive now drove it 5 or 6 times this guage has never worked it keeps counting like its searching for signal and eventually says error ive never seen it work since i got it it use to tell me it was working when i was working on the truck but since i get it running ive never seen it work i bought 3 different guages from there guys not one of them was any good do not buy there products there very cheap trash
