The hub dynamo recharges the phone. On flat, fast roads I can keep the phone topped up to 100% most of the time and then, at 100%, most of the power generated by the dynamo goes to the lights depending on which position the three way switch is in. I have a Garmin device but I prefer using the phone as the software is much better for navigation and generally more robust. It's a Sony z3 compact with magnetic charging port which is really useful for slipping into a case without having to tamper with a flimsy usb connector.
It's also one less device to carry on tour and it's worked for me for the past three years. I've used Orux maps too in the past which seems more lightweight. Functional but I always preferred Osmand. However I've found Osmand to be glitchy on occasions and I seem to be going through one of those patches now. Locus maps and Orux seem to have more connectivity options to external devices but I just need my phone as a navigational device along tracks that I've plotted which Osmand does that perfectly. I could try an older version of Osmand to see if it's OK as I'm sure it was working fine late last year under similar circumstances.
