We introduce the idea of online mapping, which is a concept not available to our Active 10/12/20 GPS devices. Online mapping should not be used if you are in, or expect to be in a region where you are unable to receive data over the internet, via 3G/4G/5G or wi-fi networks, etc. If online mapping is turned on, then the software will automatically download mapping for your location if it is not already installed on your device.
