The Garmin still needs to pair with a smartphone for all features
Hm? Mine won’t pair with anything, it doesn’t have Bluetooth or wifi.[/quote]
It’s a feature of some of the newer Garmins and allows the GPS to feed data to Garmin Connect running on the phone (the GPS will also display notifications of text messages delivered to the phone). There’s also the option for live weather updates and live Geocaching although these functions will work without a phone if you can get a WiFi connection (not very likely out on the trail).
I think that Garmin (and the other GPS manufacturers) are missing a trick not providing sim sockets on their units to allow 4G internet connections (SIM only data packages are pretty affordable); not only could you have live data but would be able to update your location (and potentially buddy up and message if someone wrote the software). Of course you could just use a smartphone and dispense with the GPS altogether but currently smartphones might be a bit delicate for outdoor sporting environments (as with an earlier post I do think that there’s a gap in the market for a rugged outdoor smartphone with good mounting options).
