I have a foot in both phone and Garmin camps, both work fine, it's mostly about finding which suits you and putting the time into getting familiar with it. I use OsmAnd on the phone and Garmin maps on the Garmin, I'm pretty sure they both use the same underlying mapping. I find the Garmin easier to read in some circumstances, particularly bright sunshine, the phone's touch screen can also get confused by being rained on. I also prefer the size of the Garmin though I could get a smaller phone. The phone's size does IMO make it easier to route plan on the fly, though I do most of my planning on a PC and download to the Garmin, plus for a big trip also to the phone as a back-up. For short urban trips, through a city centre, find the railway station/supermarket/campsite/bikes shop... I use Google Maps and audio via bone conduction headphones. I'd find that irritating all day, I even have the Garmin beeps off, but for a dense area it's easier to follow the audio than the screen. Google is also very fast at recalculating, so get a junction wrong and it'll soon tell you if there's an alternative route or you need to make a U-turn.WEBH wrote: ↑1 Dec 2022, 8:21pm Loved the komoot turn by turn voice directions, the only issue was the phone battery, which was down to 20% by the end. It's a newish model which is normally ok, so I guess I am heading for a Garmin; I'm also not sure about data usage everywhere on the phone, talkmobile are a bit cagey about where they cover, certainly not turkiye though..
I don't find battery usage an issue with either, I use a small powerbank to top both up, that will last me around three days with the phone or five with the Garmin, before needing a full re-charge, though I prefer to keep that topped up whenever I have the opportunity.
On the point above about data usage, OsmAnd doesn't use any, the maps are downloaded and the positioning is via the same GPS as a Garmin would use. I know that's the case for following a route, I'm not sure about planning. Google maps uses data, not a huge amount and even that might be avoidable, I haven't looked. I don't know about Komoot or any other apps.
If you go with a phone, I'd thoroughly recommend a Quad Lock mount, they're not cheap but having tried several others they are IMO as good as it gets, the Poncho cover takes care of waterproofing.
The above is based on my experience with a Garmin Touring (Though it's just been replaced with an Explore 2) and an Android phone.
