Check to see if GPS Antenna is connected to the Unit

One is a Blue Connector

The Other type is a Screw on GPS antenna

If you see at least 3 Satellites then need to wait for the unit to triangulate your position - May take 5 minutes for initial setup

Once you see Green Bars - GPS is Working

If GPS still not working - try disconnecting the GPS turn off the unit connect the GPS and try again.
