I Have a Question
Why can’t I get a GPS signal lock?
The most common cause of signal lock issues is external radio
interference or signal blockage: if your cell phone or AM/FM radio
are having trouble with reception, your GPS device might have
trouble getting a clear signal also. Some common things that can
interfere with or block satellite signals are
Radio broadcast towers or signal repeaters
Localized radio signals (like at an airport)
High frequency power lines
Tunnels, large bridges or overpasses, parking garages, etc.
Tall buildings or canyon walls
Dense overhead tree cover
Another common cause is window tinting. No, really. Some window
tints have such a high metallic content that they can interfere
with radio signals and increase the amount of time it takes for the
device to get an initial lock. If your windows are tinted, try stepping
outside the car or holding your device near an open window.
