Is it possible to use a USB "Y" cable from the VIRB Elite USB port so that an external microphone can be connected to the Garmin external microphone cable while the other "Y" connector is plugged to a charging source? My upcoming European Alps motorcycle trip would require the VIRB Elite to be connected to a USB power source on my motorcycle as the battery can not provide 7 hours of recording as the 64GB memory card being used.
