FAQ

Does it do MPH and KM/H, or just MPH please?

The K2 Speedometer only displays MPH, and the speed unit cannot be adjusted

Why does the screen sometimes show "__" or no speed?

This usually means the Car Speedometer is temporarily not receiving Gps signal. Please drive in an open area with a clear view of the sky.
Please use our provided cable, not yours. Because the current of the power cord is different

Will it work in tunnels or underground garages?

This is a GPS-based speedometer for cars, so signal may be temporarly lost in tunnels or underground garages. This is normal for all Gps devices

Why is the speed sometimes inaccurate or 1–2 MPH off?

K2 uses GPs satelite data to calculate speed. Minor diferences (1-2 MPH) may occur due to Gps signal strength, road conditions, or weather
This is normal for GPS-based devices and similar to smartphone GPs speed readings.
