Review: Inexpensive and useful - This worked pretty well. I have a heads-up display on my car, so I wanted to get one for my daughter. Her speed control is not very good. She tends to drive too fast, then too slow -- not at a steady speed. I am hoping that the digital readout will make her more conscious of her speed. Since I started using a car with an integrated heads-up display, I've become much more conscious of my speed. It's easy to install. I would recommend getting a USB hub as it will use up one of the USB ports (nowadays, those are cheap and available). It only does speed measurement and it's as accurate as GPS can be, which is to say not as perfect as an integrated HUD. However, the device can be calibrated for accuracy (add or subtract a few mph, as needed). It also shows direction (North, East, South and West; when going in between, both lights are lit (e.g. both N and W when pointed northwest). The cord is unsightly, but if you saw my daughter's car, that would be the least unsightly thing you'd notice (think pizza boxes and water bottles). It was not obvious to me how to position it so that the display was perfectly straight up and down (if that matters to you) because her dashboard is curved. I found the best orientation and left it at that. It comes with a reflective rectangle, but making that match up to the display was not an obvious task and frankly the display is bright enough without it (although I have not observed it during night driving). This device is so cheap it's really a wonder why anyone would go without a heads-up display. Well, I think my fussy wife might object to the visible cord and even seeing the device on her dashboard. But for an after-market device, I find it perfectly suitable.
Review: Great Idea but either broke or doesn't work - Great visibility, great idea... doesn't work at all. 1) Never stops searching for satellites 2) never works. 3) the manual is readable but not the best. Is there a reset? What if it gets stuck searching for GPS satellites? update: replacement DEVICE WORKS PERFECTLY

## Questions & Answers

**Q: No display on screen, no power**
A: Check if the USB cable is damaged. Replace the USB cable for testing, and prohibit the use of voltages exceeding 5V.

**Q: No speed**
A: The flashing power satellite icon indicates satellite search status for underground parking garages, tunnels, and overpasses. When obstructions prevent satellite connection, move the vehicle to an open area to restore normal operation.

**Q: After the vehicle stops, the speed will still be displayed.**
A: Underground parking garages, tunnels, overpasses, and shielding may cause unstable signals and satellite drift. Please drive to an open area.

### ⭐ Works great at first. After 5 months drains battery and causes CAN BUS error codes.
*by M***. on April 8, 2025*

Worked wonderfully and I loved it for 5 months. Then started draining my battery and causing 6-10 "U" Can BUS Communication error codes on start up. I bought three of these for three different vehices and so far two of the three failed in this way. For the five months it worked it was awesome but it is obviously unusable with such a short life and troublesome failure mode. Very disappointed.
