Car HUD Head Up Display Lechnical Solar GPS Speedometer,Car Wireless Solar Digital Speedometer with LCD Screen Overspeed Alarm KMH/MPH Time/Altitude/Temperature/Speed Display

Very good little device if you want know when you break the speed limit. Easy to install and set the speed at which you want to receive the audible warning.Self contained so no wires to the car. Long battery life after each charge. Two weeks. You can’t rely on the solar charging to work in the British winter. But may perform even better in the summer. Starts up when you get in the car and switches off when you leave. Made of cheap looking plastic but does the job so well it still gets 5 stars.

It’s great and much cheaper than a speeding ticket

Packed up after six months. I fully charged it put it in the car again and it slowly died over the next week even with the sun on it, avoid!!

I live in the UK and the speedo on my imported car shows only Km/h. I've been using this for over a month and find it gives a reliable speed reading. After the initial charge the solar charging has kept it topped up (no need to for USB charging cable).The instructions are hard to read but I took a pic with my mobile on 3x zoom which helps. The time gets set automatically when it finds a GPS signal. The bottom right of the display shows the vehicle internal temperature by default, but it can be changed to show elevation instead - I forget how I did it - trial and error. Overall, very happy with it.

Excellent speed display, easy to install and easy to read day or night. Seems to be charging well via the solar panel. Not sure of the accuracy of the speed as it's different compared to my dash cam. Either way they both show less than my car speedo. So at the moment it's a good buy.

If I could give this little thing ten stars, I would!

It's seems to be working, but sometimes it can't find a signal, I drove 7 miles home then it found it.

Excellent item. Just initially charge it up then place it where you want . No dangling wires and the solar panel keeps it charged up from then . Recommended to all great seller
