While CarPlay and Android Auto will get GPS data from the phone, the VLite can also provide this data with the GPS Antenna installed. If the VLite provides the GPS data, it will save your phone's battery from draining as fast. Currently the Vlite's GPS Antenna is not required to be installed, however Apple has talked about requiring GPS data from CarPlay devices, such as VLite VT2, in the future. So you might consider to install it now incase it's needed in the future.
