Mulcort Car Wireless Headup Display Solar GPS Digital Speedometer with LCD Screen Overspeed Alarm KMH/MPH Time/Altitude/Temperature/Speed Display

One of my boats is a new Boston Whaler Super Sport which is sort of their entry line boat without anything in the way of gauges other than a tachometer. Where I boat does not have any speed restrictions except for no wake zones which is just that, no wake. Just for fun I thought it would be neat to have a speedometer and trip meter, one that I didn't have to hardwire. This little unit works very well so far, although our season ended a bit short I really didn't get a chance to test it longer. It is pretty accurate speed wise up until about 40 mph and then it starts to lag a bit compared to my phone GPS and my car when I put it in to verify speed accuracy. No big deal, I don't expect Perfection at this price point. What I do like is the solar powered part and so far I have not worn the battery down at all, but the worst day was overcast at best so it's really hard to say how long it would go at night time on a full charge. But it does have charge port so there's always the backup. I do wish it had a bit more mounting tape or other options to secure it. I put it to use for about 2 months in a wet saltwater environment with some wash downs and the tiny piece of double-sided tape they provide seems like it's only going to be good for another few times out before I have to get some better tape. Otherwise, that's about the only small issue.

Love the fact that it is wireless as well as corded. Took it out of the package and charged it via a usb cord for 12 hours. Then charged it using its solar panel option. It’s working well. The only issue is the readout panel is hard to see when it is bright outside.

The unit is quite small and sits on the dash with a sticky pad that I hope comes off cleanly when I turn the leased car (EX30) back in a couple of years. I found it to be very accurate regarding MPH, and pretty accurate regarding elevation. I liked that the time was included as well. It surmounted some of the shortcomings of the EX30's "one screen" Tesla-like implementation - since the driver alertness warning would ding me if I spent too much time looking at the center-mounted screen trying to figure out where in the stream of menus a given function was buried. I now never look at the MPH on the center screen. Certain worth the price if you have a car lacking a driver's side screen...

Do not buy from this seller. Seller does not offer full refund and hassle to return. Also I found it cheaper from other seller. I message the seller for return but said will only issue 50% refund and does not cover return shipping. Also product creates glare on its screen when at direct sunlight that makes its screen hard to read. I don’t recommend buying from this seller.

Absolutely awesome!!! After reading several negative reviews I was concerned about purchasing this item. But I have no regrets. Every function works perfectly. I have larger size tires than the factory correct size on my 70 Chevelle SS that causes the speedometer to be slow. Depending on the speed my speedometer was14 MPH slow. So this item is extremely helpful to know the correct speed. I don't depend on the solar charging system fir charging because my car is secured indoors when not in use. So I simply charge it when needed. And it lasts weeks. It is wonderful not having a charging cable running to the device. And I enjoy all the functions provided. I have verified the speedometer is correct with several other devices and vehicles. I highly recommend this item.

Seems to be right on as far as speed, took a while to change to mph/Fahrenheit.

The 12-hour time format shown in the images, is NOT available in the settings, it ONLY has military time mode.

It's so, so. I bought it to use for a ST1100 motorcycle. The speedometer are notoriously inaccurate. The solar charging works and is one less complication. The instructions are typical Chinese confusion. Take a close up photo of instructions so you can read, and you'll eventually figure out they over complicated them. There is an option to add/subtract the readout speed. Isn't this ridiculous for a GPS? Yet, it needed to be adjusted -2 MPH after checked against three others. I'm not a fair weather rider and need to know when ice presents a hazard. The temp gauge is plus 7-8 F typically. I found the display easy enough to read day or night and the unit is small, not gaudy, just the right size for my application.

Es muy fácil de instalar y ponerlo en funcionamiento.
