Is it worth updating gps
While the Series 2 doesn't have the standalone LTE support that some projected, it can do a lot more on its own now thanks to the addition of a GPS within the watch.
Before, you'd need your phone in your pocket to accurately track your location, which meant another thing to haul around when you just wanted to go for a run.
Map downloads require sufficient memory on your device - you may need to use an appropriate micro SD card (not included) to store and access the downloads if your device’s internal memory is not sufficient.
If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.
Now, with the GPS inside, you can leave your i Phone at home and still get spot-on tracking results.
especially with the smarter watch OS 3 about to roll out. Here's our take so far, based on the specs and our hands-on impressions from the Apple event. I had similar problems with the 2017 Navigation update disks on my 2016 ADV.
