Yes I have and it works very well. I have encountered a few inexplicable program closes, which have been easily fixed by reopening it (make sure you have a copy of your route saved on the phone rather than relying 100% on the cloud storage). There are a few cases where text is too big for the buttons on which it is displayed, so that some easy guessing is required to figure out what the button does. Aside from these issues which I imagine will get fixed in future releases, it is a really amazing piece of kit. I am toying with the idea of getting something with a larger screen (eg Nexus 7) that can be tethered to the phone for data, and be used in kneeboard style, but have held off so far because a) the phone is working fine, b) I can't decide what to get, and c) there seem to be some reliability/speed issues reported for some devices.
