I loved the Garmin Drive wireless route transfer to the XT before I dropped it in favor of the MRA Nav.
The Drive app for the XT is convenient. I used it for a brief time before deciding on wired transfer as my preferred method. The problem is that Garmin can break the Drive app with updates. It happened a couple of years ago, where the app was unusable for about 6-weeks. And my understanding is that they broke it again in the last month or so. For me, that's too much risk to depend on.
Moving forward to the XT2/XT3, you have to use the Tread app for wireless route transfer. Much has been written about how that can mess things up. The bottom line it's to be avoided.
For a longer trip where I might be in a position to have to modify or even create new routes, I carry my small MacBook Pro laptop with me. MRA Routplanner works great on it. The Mac takes up little space, so no big deal. As always, to each is own.
