Frequently Asked Questions
Will a GPS Speedometer work on a motorcycle?
Yes, most models are compatible with motorcycles as they use universal USB power. Ensure the mount fits your bike dashboard securely. Check that the display is visible over handlebars.
Why is my speed reading off by a few MPH?
GPS units may have a small error margin of about 0.6 to 1.8 MPH. This is standard for satellite-based tracking devices. Always check settings to confirm you are using MPH.
Do I need to connect to my car OBD port?
No these devices use GPS satellites instead of car engine data. They power via USB without wiring to OBD ports. This keeps car electronics safe from modification.
Can this work indoors or in a garage?
No GPS signals are blocked indoors. The device needs an open sky view to lock satellites. It will not work in tunnels or underground parking lots.
Does it save total mileage when the car is off?
Many units do not save data without power. Some have ODO tracking with auto-save features. Check specific model specs before assuming ODO tracking is present.
What if my windshield has metal tint?
Metallic tint can block GPS signal reception. This causes weak or lost connections during use. Place the unit away from tinted glass for better signal.
How long does the GPS lock take?
Initial locks typically take 10 to 30 seconds. This depends on satellite availability and signal strength. Subsequent drives usually lock faster.
Are alerts loud enough during driving?
Overspeed and fatigue alerts use sounds or flashing lights. Check volume settings or ensure display is visible. Not all models have audio alerts but visual warnings are standard.
