For me, the ability to use MRA directly from my phone without having to download routes to a sat nav or in the case of the ConnectedRide Navigator, via the app. I like the MRA interface now and you can also access Google Maps etc or, God forbid, music, What's App and whatnot (This seems to be essential to a certain demographic). Offline maps sorts out data losses. My phone isn't high end but I can see the reluctance to expose an expensive phone to the weather. I am not convinced yet but I will be trying it out this year on my Euro trips. I'm sure there will be pros and cons.
