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.
