Opposite to ken, i prefer standalone gps headunit rather than phone for navigation. Phone is too dependant on network coverage and google map/waze is not as good as the garmin map.
My friend's phone got robbed during one of her ride. I guess that's also one of the disadvantage ofusing of a phone on a bike. Safety issue.
I hate the 5 inch screen standing on the handlebar, looks weird not to mention you have to keep a lookout at it all the time. I have a friend who let it sits on the top tube and that is not so weird looking. I can't use it most of the time too as I am off road all the time. Not all places have signals. I have been using GPS since my hiking days and it is a very important equipment for me. Like me and wife, we are slow riders and sometimes we meet rides that have no sweeper or riders too fast, we just tell them to go ahead. As they know I am also one of the trail scouts, they feel free to go ahead. If I can't catch up, I can always back track using the GPS or check the map for the easiest way back. Imagine if you don't have signal and the smart phone is not working

For those riding on just roads, it OK even if you don't use GPS, right?
Furthermore, Garmin Edge's last 16 hours on a single charge, even longer on newer models. Although I have never depleted the juice, I have tried switching on at 7.00am and ride till 5.00 pm and the Garmin is still on. No smart phones , even with 2 power banks can last that long.
