You can add the time on the lower right corner of the head up display. 2、Much more functions than others. This head up display is with powerful functions. Data displayed in OBD mode: speed, water/oil temperature; voltage; fuel consumption; RPM; simple mileage; driving time; quantity of satellites; altitude; time; air‑fuel ratio; turbine pressure; acceleration test; brake test; data flow; clearing the fault code,ect. You can make DIY selection on 9 modes as you wish. 3、Much more adaptable than others. The OBD2 and the GPS mode can be displayed on the same interface. You can customize small icons as you need. Data displayed in GPS mode: speed; voltage; driving time; altitude; number of satellites; driving direction; simple mileage,ect. You can switch unit between miles and kilometers, switch unit PSI and Bar, 100KPA. 4、Much more powerful than others. As 2020 upgraded HUD display and car OBD and GPS dual system, it adopts specifically more advanced technology. We have added 10 more OBD2 protocols to improve our compatibility, which makes our products fit 98% cars. 5、The OBD2 is compatible with European cars after 2005 and cars of other regions after 2008.
