The most common reason this message appears is because the GPS antenna isn't positioned correctly within the vehicle.
A GPS Antenna needs to be placed somewhere near the top of your dash, with no metal object between it and the windshield.
If your unit will not update showing your location after driving around a few miles, try checking the position of the antenna.
Next, check the port on the back of the unit where your antenna connects, and make sure you see a PIN in the center and is not bent or missing.
In some situations, for a GPS signal to lock with a unit, you may need to drive in a circle three times clockwise, then counter clockwise three times to calibrate the GPS.
If you have tried the solutions above, and still receive this message or the GPS/map location doesn't update, please contact us for additional support or open a ticket.
