I have had the vivoactive for a few years now, but never really used it, just about beginning to get serious about it.
1. Internetless Road Navigation - I would like to use my GPS receiver in the vivoactive device coupled with a mobile application that has maps for India cached offline and achieve road navigation.
- Is this possible with vivoactive ?
- If so, what maps can I purchase for India ? Are these regularly updated ?
2. Internetless topographic navigation / trekking/ hiking - I need to import GPX files that has waypoints saved from treks in the Himalayas and use it for navigation.
- Is this possible with vivoactive 3 ? I'm ok to use a mobile phone app in conjunction, but of course I won't have internet
- If I need a topographic rendering of such GPX files, what do I need to do ?
3. Internetless Livetrack - the livetrack is a cool feature, but of course it needs an internet connection. I need to make my location known to my family without internet.
- What are the technical challenges for Garmin to use the satellite for uplinking such coordinates without internet ?
- Are there garmin devices that have contraptions for uplinking gps coordinates that are downloadable via the internet by interested parties ?
4. Lastly, is there a garmin device that does these better than the vivoactive 3 music ? What device would you recommend ? Battery life is an important consideration.
