T600 Universal Car HUD Head Up Display Digital GPS Speedometer with Speedup Test Brake Test Overspeed Alarm TFT LCD Display for All Vehicle

Super easy to set up and operate. I like that you can adjust the brightness to your comfort level. It is very small, very light, and a low profile on the dash. The readout is easy to see if displaying only a couple of the features, if displaying multiple readouts it gets harder to see all the info , I have it placed up close to the windshield so if you like it closer the readout would be easier to see. I had a different size tires installed and wanted to check the accuracy of my dash speedo. The speed readout is super fast, I picked up 17 satellites (wow) and the accuracy is excellent. Would have been a plus if the kit had included mini usb to type a usb but it only has mini usb to cigarette lighter plug. Very happy with this purchase so far. There are several kits available for hard wire install on Amazon if you looking for that pro install look.

So far so good. Mine came with the speed calibration set to 107%, had to tone it down to 102% but now its quite accurate. I wanted something to show the speed in MPH and was also looking for something to show voltage, and this device happens to handle both without issue. Unit is very light, and fairly small, but seems like its built well enough. Ill update this review it I have any issues.

I ordered this for my JDM Honda Acty as that speedo is in Km/hr, and not MPH. The first unit recieved did not connect to any satellites as it was defective. I decided to swap it out with a replacement and that one worked as advertised - I didn't even have to celebrate it as the speed was accurate out of the box. I typically connect with 10-14 satellites! Let's hope it lasts....

Good experience

After spending over $600 dollars chasing down the bugs in my Toyota Camry speedometer I purchased the digital gps hud. This is all I needed. End of story.... wish I had thought of buying one earlier.

Item stopped working in under a year. Would really like a replacement but no one has contacted me back.

I had this gps speedo for less than two years and keep my car stored for the winter so it has about a year of use. One day out of no where it just stopped turning on. I checked the power cable and it was working. Worked well while it worked, was off about 2mph which wasn’t too bad. Just wish it would last longer than the cheaper ones you can get.

The media could not be loaded. Plug and play, works great. Works much better and is more accurate than an app on your smartphone. Very accurate, it is within a couple of mph of my dash odometer which is perfect in order to avoid trouble with the police. You can set one alarm and if you go over that speed limit it will beep about 2-3Seconds to alert you. I highly recommend. I leave it plugged up as my cigarette lighter has no power when the car is off, check your car and unplug or get a switch to turn it off if your power does not shut off.
