ACECAR Digital GPS Speedometer, Universal Car HUD Head Up Display with Speed MPH, Compass Direction, Fatigue Driving Reminder, Driving Distance, Altitude, Overspeed Alarm HD Display, for All Vehicle

Bought an 85 station wagon. The speedometer didn't work. Bought this and has been in the car ever since. Love it! Accurate on point would highly recommend

Not the simplest out there, but Ok. The trip meter is great. Don't lose the directions!!! Compass seems accurate. Very easy to read

Works great! Multiple settings and configurations to suit your needs. I attached this one to accessory power so it is only on when the battery is engaged or the engine running. I am using double sided tape to hold this to the top of my dash right above and to the right of my steering wheel.The only reason I am not giving it 5 stars is it is a little difficult to read in intense sunlight. The LED display just cannot output enough light. I suggest the next version have a small shroud around the top and sides to create a little permanent shadow on the display. As it stands I am going to try and fabricate something out of a plastic sheet and a heat gun.

Had a hard time figuring out the settings ! After I got it configured it’s just simply Bad Ass !! Accurate & Fun to look at travel time , wind speed etc !! Great Device 👍👍

White speed indicator hard to see in bright daylight otherwise unit functions great. Blue LEDs easy to see. Red function indicators easy to see also. I like the milage and time elapsed functions. Great for taxi fare calculating

Slightly above a toy quality. But they look great in flea market race cars

So much good stuff with this unit. Suction power for mount is excellent ! It has the newer style double cup base, so when you install on windshield it stays there ! Unit takes maybe a minute to find satellites average around 12 to 15 satellites acquired 19 most I have gotten. Have checked accuracy against known good speedometers is right on the money ! The display is a backlit segmented display (not sure of proper name) all the different parts of display are visible and only the ones selected are backlit. I use speedometer, compass and # of satellites available. Has a clock but I never got it to set (I didn’t read instructions!) Unit has one button on top used to cycle threw all available display options. Unit has power cord (no power supply) has to be plugged into a usb power source. Display is ease to read with my 67 year old eyes with no glasses on. Last but not least unit is very affordable I paid $27 and change (had a coupon) so I highly recommend this unit !!!

Update: Compass works well, need to get it out and moving. Don't judge it by moving it around in your living room.Five stars._________It just arrived, I got this for the altimeter and compass, don't really need another speedometer. Altimeter seems ok, compass points N no matter what way the box is orientated. I'm hoping once I get this driving around the compass will come to life. I'll reedit this once I know for sure.
