Product List

Is this heads up display for cars wireless?
No. This is a USB-powered car HUD, not a wireless or factory-built system.
Will it work in tunnels or underground garages?
This is a GPS-based heads up display for cars, so signal may be temporarily lost in tunnels or underground garages. This is normal for all GPS devices.
Why does the screen sometimes show “—” or no speed?
This usually means the device is temporarily not receiving GPS signal. Please drive in an open area with a clear view of the sky.
Can I switch between MPH and KMH?
K1 displays speed in MPH only and does not support MPH/KMH switching.
If you need this feature, please consider our H1 model, which supports MPH/KMH conversion.
Can I calibrate or fine-tune the speed reading?
No. K1 does not support speed calibration.
The speed is calculated directly from GPS data for simplicity and ease of use.
