I see the thinking. Kinda safer having Your navigation separate.
I'm not sure about the 1000. But I do find charging Garmins Nice and fast. I've ridden loads With a 910xt both charging and recording. It still charges at less than a minute per percent. I Guess its Down to taste. for me just having the one Device seems easier, as you'd have you speed together With navigation. Making it easier to know in advance when to turn.
