C60 Universal Car HUD Head Up Display Digital GPS Speedometer with Compass Time Fatigue Driving Alarm Over Speed Alert for All Vehicle Include Truck Electric Hybrid Automobile

This amazing gadget saved us a lot of work. We didn’t have to replace our speedometer. It is easy to use but I have never successfully gotten the speed projected onto my windshield. Beyond that, it seems fairly accurate but when I pass the “you were going this fast” on the freeway it is consistently off by about 3 mph. So who knows who is wrong.

Nice unit that does what it's supposed to instead of trying to be an all in one unit as so many of the obdII connected units try to be. One issue I have with it is that it reads 2-3 mph fast. I know this because the two Garmin gps units I have tell me when they are parked right next to this one while driving. Also, the reflective patch included with the unit is virtually useless in bright sunlight. I shall be experimenting with other tints to see if anything works better.

This was opened as a Father's Day gift last night and I was horrified; it was clearly used with scratches on the display and significant scuffing around where the charger connects. I paid for NEW. My husband tried to be gracious, and will try it out today to see if it even works correctly but it was not what the description said or I intended to gift him. Very disappointed.

It does the job sometimes. I drive a car in the US with KPH instead of MPH on the speedometer, i bought this to make driving the speed limit easier and it will get reasonably accurate, compared to the radar speed warning signs.As for the ability to reflect off your dash? Non-existent..maybe if your windows were extremely dark you might squeeze some visibility in day time. But if you want to take advantage of the 'Heads up Display' this is not the choice for you. The display is far too weak and cars generally need a special film built into the windshield to support heads up display. As for the film provided, it still becomes difficult to see even in a garage.

plugs into cig lighter and just works, takes a minute to find a signal but once on it reads speed fine.it has more functions than i choose to use . my speedometer stopped working now i use this .

The media could not be loaded. Purchased this to put in my car for my teenage driver. She complained because my car didn't show the speed digitally. With this she can rest assure she's going the appropriate speed and the fact it has a alarm when you exceed the speed limit help ease my mind. Very simple to sit up. The warning sound is loud.

I purchased this since I run a different tire size than stock. You need to drive some and then when parked change it up or down depending on if its over or under. Use an already trusted GPS with speedo to accurately calibrate it. It took me maybe 4 times of driving and tinkering with it to get it accurate up to 95. The over speed alarm works great as well to remind yourself that your hitting the pull overable speed area

Extremely easy to set up and adjust. Very adequate display. Easy to read at a glance. Unfortunately indicates speed higher than actual by about 3.5 mphThe C80 is very hard to adjust but appears acurate within .5 mph. I wish my C80 was as easy to adjust as the C60 or my C60 would be as acurate as my C80.I would prefer the C60 handsdown if it were accurate due to ease of adjustment and adequate display.It would seem as if these 2 units were made by 2 separate companies but I do not know. If the C80 was not so acurate and since I'm not aware of other brands, I would not by a C80 again. All too sad!
