A riding buddy has a 520 - when connected to my Varia, every alert kicked on the screen backlight and it significantly shortened the battery life of his 520 to the point that he gave up and disconnected. I'm not sure if that's been addressed via firmware, yet.
Good intel. I would consider a 520 but if the Varia drains it, I might avoid.
