G20 New GPS Speedometer Car Hud Head Up Display, Universal Auto MPH Digital Speed Gauge Cluster for Cars Truck Motorcycle ATV SUV Pick-up Scooter Golf Cart

Amazing product. Had to try serval different speedometers and most of them not accurate. This one is accurate to the mile. Strongly recommend.

I bought the VJOYCAR C60 several weeks ago and am using it in a 2019 vehicle that has a digital Km/h display but not mph. I wanted digital mph also. The GPS speedometer works perfectly. Everything advertised about the unit is true. Set up is no more complex than connecting to USB power. It takes perhaps half a mile to lock onto a satellite and do its housekeeping before speed is displayed. Out of the box it was within +/- 1 to 2 mph.I did choose to recalibrate the speed slightly. This achieved by pressing and holding the up arrow and enter buttons at the same time. I found that pressing the up arrow just slightly prior to pressing the enter button got me into the calibration subroutine every time.Another nice feature is upon stopping, such as a traffic signal, the trip mileage followed shortly by trip time in minutes are displayed. Stop signs tend not to be long enough for this feature to activate. Mileage and time are displayed in whole numbers (no decimals), so the longer the trip, the better the data.Now, there are what appear to be a number of similar devices out there brand labeled by each reseller. The nice thing about the VJOYCAR reseller is that he contacted me personally after my purchase to deal with any issues. I had not noticed that the unit requires a wired USB connection for power, so he kindly supplied a 12 volt adapter so I did not have to sacrifice my USB connector normally used for phone and music.All in all I am happy with the device. The true test will be our Midwest winter temperatures, but for now I'd buy it again.

I bought this for my 2012 Mitsubishi Lancer. Sometimes when I'm driving with my hand on the top of the steering wheel it covers my speedometer and I have to keep lifting my hand to see it. For just under $22 I figured it was worth a shot but wasn't expecting miracles for accuracy. It comes nicely packaged in a small box, the unit itself feels pretty light weight. One thing I did have to do is add a small piece of thin gasket material between the mount and the unit because it was a loose fit and I didn't want it bouncing around and falling off while driving down the road. It does come with 3M double sided tape but I removed it and added 3M double sided outdoor tape that is a little more tacky. The problem I ran into was my car was sitting in the garage at night when I put it on my dash and the next morning it had fallen over on my dash. So the next day, which was a hot day, I left it sit on my seat while I was at work. The combination of the hot dash and the tape sitting in the sun seems to have created a better bond and it has not fallen off my dash since.Now for the technical aspects. It comes with instructions and is very easy to set up. At start up I have never had to wait more than 2-3 minutes for this unit to pick up the signal and that's both sitting and driving while it connects. It comes with a flat cord that has the same connections that an Android device has, but it doesn't come with an A/C adapter for cigarette lighter plugs. I don't have a USB slot in my Lancer so I bought an adapter on Amazon for less than $5. It does have a 2-3 second lag during acceleration and deceleration but once you're at a steady speed it calibrates and adjusts quicker. I did notice that the unit I got seems to run +1 mph more than my speedometer but that's no deal breaker. Overall the unit has a cheap feel to it but I'm impressed with it's accuracy. The screen is bright and clear and easy to read during the day and night. I use it daily for going to work and also on road trips.*Update* The fatigue alarm that goes off every hour is annoying. I have not found a way to turn it off. If you can remember to power it off and back on before it goes off then it won't beep at you. Cloudy and foggy days seem to throw off the accuracy, it seems to run about +2-3 MPH on those days, but it has to be thick cloud and fog cover.

If you're a fan of digital dashes, or just want your passengers to see the speed, get this product. This looks great at night, especially when you don't see the cord. The product looks as advertised and does go into triple digits.Only problems with this are build quality issues. The micro-usb cord that it comes with is very sensitive, when going over speedbumps and potholes, the cord gets jarred a small bit and the screen will go back to its "loading screen" that it does while trying to find a satellite when first starting up the car. The "loading screens" last just a few seconds and are only caused by the cord becoming jarred loose. 10/10 otherwise.

Used for 350+ miles. It takes more than a minute to find a GPS signal and begin working in Albuquerque. Green is really nice although the sun at a certain angle washes out the clarity. Adjustment +/- 1 MPH is not pinpoint accurate, but close enough. Easy to adjust that (enter plus up arrow to adjust, enter plus down arrow is NOT the adjustment so you have to cycle almost all the way through to decrease the MPH). I did not have to mount using the sticky pad as the device wedges against dash and windshield securely. Using in a Toyota Tundra. May be too bright for night but have not used in the dark yet. A loud tone periodically sounds and I do not know what that means. Indicators after stopping trip not useful, time travelled and distance as the Tundra instrumentation does that anyway. But the primary purpose as a HUD is fine although the device does not wow me so only 3 stars. If that is all you need too it is probably going to be okay.

Never once has it worked and I didn't even install and try untill it was to late to return. (Got last winter for a project truck and didn't put in until spring). Don't buy this unless you have time to do returns.
