Interestingly, like many have advised above, I've moved away from this. I now prefer to use minimal navigation electronics (ex: garmin forerunner, if at all) and no longer ride with a dynamo hub. IMHO phone navigation is useful in large cities, not so much on open roads.
Wow. You went from having one of the most powerful charging systems to ... ... none.
