Car Home Ultra uses the data connection to retrieve your current address and weather. To reduce the location update rate follow the instructions below:
1) In the settings menu, make sure that “Powered Mode” is unchecked. This option forces Car Home Ultra to use the max settings when connected to a power source like a car dock.
2) In the settings menu, select “Location Update Rate.” Choose one of the lower rates like 5 minutes or 60 seconds. This controls how often the green location bar updates.
