GPS Speedometer Universal GPS Extend Digital Display 5.4 inch HUD Speedometer MPH/KMH with Over Speeding Alarm for All Vehicles Cars Bicycles

I changed to a full-face helmet after a very cold morning and considering safety factors. But I had to take me eyes off the road and look down at the speedometer on my scooter, and, as with age, my vision doesn't change as quickly to focus when I look back up. I made a half windshield with a neat mount for this unit, just to get me speed. Then I was absolutely surprised that it worked so very well. Thank you!

I bought one some time ago for myself. It is especially useful because, at my age, I can't usually see the speedometer in daylight. My wife liked it too so I bought this one for her.We only use the speedometer part. But it would be nice if it had it's own battery to enable it to save the time and mileage data.

Works well. Easy to read.

This works good but when you remove power all the mileage is erased. So it’s not what I need.

I replaced a Tom Tom with this because it would be easier to read the speed. I mounted it in the same location. This unit had problems with accessing satellites. I moved it around, but still would work a small percentage of the time. Tried plugging it into a lithium battery pack, thinking maybe the vehicle's power wasn't clean. No change. The altitude is always metric.

This product is hard to keep calibrated. Not a very reliable system. Will only use it if the garmin fails. It’s inexpensive and you know the old saying you pay for what you get

Works perfect for an auxiliary speedometer. Super clear even in the middle of the day. I use for calibration correction on customer cars. Unit comes preset at 5mph higher than actual, but can adjust manually.

I had purchased this for my father to use in his classic car as the factory speedometer was a bit tricky to him to view, this unit seemed to match his speedometer and a regular GPS within a mile, even factory speedometers are not always 100% accurate nor are GPS Satnavs, We were quite impressed with this unit and would suggest to others especially if have a deflective speedometer but like anytime of GPS/Signal l can lose signal at times
