VJOYCAR 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

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.

Only annoyance is setting it to MPH is a bit finicky but thats what instruction are for, It is accurate in all my uses, my speedometer just doesnt work during the winter and I got too use to reading from this its rather nifty. For some odd reason it doesn't like some numbers (62 and a few others) and just refuses to display them it just oscillates between the numbers (flickering from 61<->63) it's a nonissue but an oddity.

Good for the price, I got this as a cheap fix for not having a speedometer at all on my boat. In speed display only mode it is bright enough to read in sunlight. With the entire display on I can barely read speed and can't read anything else. I ended up buying a small flat power bank and mounted that behind the dash just for this. Pros: - It gets the job done and is better than using a phone for speed. - Is readable in sunlight - Has a flat back so you can sticky tape it or velcro it to your dash. - You can calibrate it, in case the speed is incorrect (which it was compared to my car & phone). - While I haven’t gotten it “wet” it has so far not had any issues with light spray and a little moisture. Two complaints, 1) It is USB powered only, which means you either need a power bank or separate voltage converter to power it from 12v. I would have rather this just been 12v direct. Plus having a micro usb port coming out the side makes for an awkward cable situation, hard to install cleanly. 2) It isn't the fastest to update, probably once a second, and you need multiple readings to get a reliable speed. So if you are accelerating you need to be patient about seeing just how fast you are really going. If I still had my old car that didn’t have a working speedo, this would be my go-to quick fix on that as well. Long term there are GPS dial speedos that look and perform much better, and I will get one of those for my boat, but they are 10 times the price. If you are powering this via a power bank keep in mind the power usage is very low... so low most power banks will auto-shutoff to prevent storage power leakage. This was quite frustrating but once I found a cheap power bank that worked I didn’t have to charge it even after hours of use.

I am very happy with this purchase! Here's what you can expect: The unit comes with a small mount and some 3M tape, which can be applied to the mount or directly to the unit itself. I added some Velcro to mine. After you plug it in, it will take a minute to find the satellites. As others have mentioned, you will probably need to calibrate it. This is easily done with the help of a passenger. I recommend calibration at 70mph+ (when safe and legal to do so of course) for best results. You only need to do this once, after which the unit will display your speed with a high degree of accuracy. The unit is fairly responsive. Not the instant response of a stock speedometer of course, but still pretty good. For a GPS receiver I was impressed. Perfectly acceptable for everyday driving. The display itself is large and easy to read. The manufacturer really dialed in the brightness perfectly. I drive a convertible and can still read the numbers even in direct sunlight. At night, the unit is bright - but not too bright, although it is close. Any brighter and it would be distracting; any dimmer and it would be hard to read during the day. Again I was impressed. If you're looking for an accurate, responsive, easy to read speedometer, you won't find a better one at this price. An excellent value for the money; you really can't go wrong. I wholeheartedly recommend this item.

When I was first getting setup I couldn't figure out why is kept shutting off. It turns out the power plug in is loose and only makes a good connection at certain angles, but I was able to use some blue tac to hold it in place. Other than that, works great!

Only been using this for a couple of weeks, but it works great. I installed a USB port in our golf cart and plugged it in, and it worked immediately. The holder lets the speedometer click in place, and can be easily removed. It does fit a little loose, but overall great value for the price. We are getting our golf cart approved as an LSV so we can drive on the streets of our town, and a speedometer is required.

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.

I'm using this in an old 4x4 that we tow behind our RV. The speedo needle is broken on the truck anyway, so this was a good cheap way to get a dedicated speedometer and odometer to track miles driven since the built-in odometer runs even when being towed. This way I can track engine maintenance. I also wanted to have proof that I'm not going 'WAY TOO FAST'. My passengers always tell me to slow down when we're only doin' 40. Not sure why? Maybe because the truck is 25 years old and basically pieced together from spare parts. Where's the confidence in my mechanical prowess?? You need the shaking to make you feel alive! Anyway. This is a review of a gizmo, not my poor old truck... This is the first one of this type of unit that I've tried, and it does seem to work okay, the odometer says I've gone about 35 miles since install so more time will tell. - The GPS lock varies from instant to as long as 1 minute, probably depending on how far the vehicle moved (towed) since it was last driven. - The 'total driving time', which is the bottom left field, this one I suspect only increments while you're moving. As others have said, a 20 minute drive will invariably read much less if you were sitting still a lot. - The altitude, as others have mentioned, seems like a waste. It's always there when the vehicle is moving, that field alternates between the time provided by the GPS system and the altitude. I'd rather just have it stay on the time, or possibly alternate between the time and odometer (total miles driven with unit powered on). Also, the time is military (24hr) format, not configurable. If that matters. - You don't get the odometer display unless you're sitting still, and then that field blinks constantly with the total miles driven. This unit doesn't have an external antenna, so putting it back under the dash or back under the lip of an instrument cluster might interfere with the GPS lock.
