Product List

The device doesn’t show speed in tunnels or underground garages. Is it defective?
No. GPS signals may be temporarily unavailable in tunnels, underground garages, or enclosed areas.
Once you return to an open area, the speed display will recover automatically.
Why is the speed sometimes inaccurate or 1–2 MPH off?
K2 uses GPS satellite data to calculate speed. Minor differences (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.
Can I adjust the brightness manually?
No. K2 is designed as a simple, plug-and-play HUD and does not support manual brightness adjustment.
Can I switch between MPH and KMH?
K2 displays speed in MPH only and does not support MPH/KMH switching.
Can I calibrate or fine-tune the speed reading?
No. K2 does not support speed calibration.
The speed is calculated directly from GPS data for simplicity and ease of use.
