Review on Universal Car HUD Head Up Display - ACECAR Digital GPS Speedometer With MPH Speed, Compass, Fatigue Driving Reminder, Distance, Altitude, Overspeed Alarm And HD Display, Suitable For All Vehicles by Matthew Henderson

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 !
