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

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.

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.

This looks and works great in my 1951 B3B Dodge truck!

Everything on it worked, the wires are in tight and there is a decent length of wire.The backlighting could be better, it is hard to see the numbers with it lit unless you are looking straight in at it.A few things to mention since I see some negative reviews from people that do not know how it operates.The odometer counts up when it is first turned on until there is a GPS signal and then it goes to the mileage.If your antenna is not near a clear view to the sky it could count up for a while.The back lighting, signal indicators and high beam indicator will not work unless the speedometer is powered on.The push button connects to a white wire that is labeled on the speedometer and the other wire goes to ground not positive.Don't expect it to perform well if the antenna does not have. a clear view to the sky.

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

When first installed. worked great. Then after 3 weeks. Started working and not working. When it works it is accurate. Now hardly ever works. Getting in touch with anyone at Amazon! Well, that's a waste of time.

Although the instructions are a bit vague, the installation was pretty straight forward, however they include a remote button, but don't even mention in in the instruction except to say on of the wires that comes out of the unit connects to it, no mention of what to do with the other terminal except in the Q&A below the description (it goes to ground) ... also, I was a disappointed there was no trip counter, but you can set a speed warning buzzer? Crazy. Anyway, I compared it to the GPS speedometer on my phone and they were identical. Lastly, finding a spot for the GPS antenna was a bit of a challenge as I didn't want to put it on the outside of the windshield, and vague instructions advise against sticking it on the inside of the windshield as the front of the antenna needs to "see" the sky. On a boat or motorcycle this wouldn't have been an issue, but on a car I don't know how many people want it on the outside of the windshield.
