What is the difference between the blue and green dot when my location is acquired?
The green dot represents a real-time locate. The device was able to acquire a cellular connection as well as current longitude and latitude information. The unit has a clear view of the satellites. The blue dot represents old longitude and latitude information. GTC was able to acquire a cellular connection, but not current longitude and latitude information. When this occurs, the blue dot represents last known location data. GTC currently has an obstructed view of the satellites. This sometimes happens when a vehicle enters a parking structure. A blue dot will probably appear at the entrance to the parking structure, as that was the last point in which GTC had an unobstructed view of the satellites.
