Have you been told this is possible?, as far as I can see the 30x does not have Wi-Fi or Bluetooth connectivity, so you will have to use the USB interface, although Android devices also have a USB interface, I don't know of anything that runs on an Android platform that would send files directly to the 30x via say a USB hub. The 30x does perform Unit-to-unit transfer (sharing data wirelessly with similar units), but you would have to find an Android phone that supports ANT wireless technology (they do exist apparently) and also an Android App. that would communicate with the 30x using the ANT interface
