The CommandGPS device tracks every minute when the vehicle is on and every hour when the vehicle is off.
CommandGPS is GPS tracking a vehicle, cell phone GPS tracks the phone. Where the cell phone goes, so goes the GPS tracking information, which doesn’t necessarily have any bearing over the location of your vehicle.
When CommandGPS is connected to your vehicle it receives a reliable source of power. Cell phones with GPS have a tremendous drain on the cell phone battery. If the battery is dead, the cell phone user simply turns off the phone or disables the GPS function, you will not receive any GPS data.
