I don't think so, no. You import routes over wifi through Strava or RWGPS, but RWGPS is the only way if you want TBT navigation cues. You can do that without connecting to a phone, but you can also use your phone as a wifi hotspot if you aren't near a network. To my knowledge there's no way of taking a GPX file directly from your phone and installing it on the ELEMNT.
