I want to share a location from my iOS app (Mundus) to Garmin Drive. However I can not find out what data Garmin Drive is expecting me to offer in my UIActivityViewController.
Apple Maps shares to Garmin Drive, but Google Maps doesn't. It therefore appears that it's not as simple as just offering a VCARD or. GPX (both of which I've tried). This must be something Garmin wants to encourage, so where is it documented?
