Truck GPS Speedometer 6.2 inch Extend Digital Display Vehicle Odometer Trip Meter Course Overspeed Alarm MPH/KMH

worked good

fast shipping works well easy setup

It's a decent speedometer if you just need a speedometer. Accurate to within a few mph, but it doesn't update quickly enough and it's not accurate enough for TSD rally. Instructions are so-so. Expect to spend some time fiddling with the buttons on the back to get it right.

It works great in my vehicle, my speedo quit working but this device shows me my exact speed

Has trip time, trip mileage which zero out when powered off. Best part for me is total mileage (odomter) which does not zero out when powered off, but continues to accumulate. Also has speedometer, clock and altimeter.

It is only about the correct speed. At 65 you would have to show 70. And the odometer is not readily accessible. And it stayed bright when it is dark.

works ok without a lot of lag i use a modified phone holder to hold it. I live in a speed trap area and it puts me in the ballpark. I have a vintage truck with cable speedo that is too much hassle ($) to hook up to my 5 speed manual trans. I wired in a aux. power outlet that shuts off with the key.

So far it's working good, wasn't hard to install and the display is easily read,if it was stable. I couldn't tighten it up enough to hold it in place, and the stem broke, so now it's basically junk.
