I don't mean to be terse, but you did not ask any question. You simply made a feature request, which does not necessitate an answer. I assume by "locations database" you're referring to stored waypoints, tracks, and routes on the device. Is that correct?
We have longer term plans to include more navigation and mapping support in Connect IQ, so this kind of feature will be available in a future release. In the meantime, there are a few examples of ways people have found creative solutions to use Connect IQ to manage this kind of information:
dwMap: https://apps.garmin.com/en-US/apps/2750f280-82f4-4f21-a32c-57acc7ce4870
Hike: https://apps.garmin.com/en-US/apps/39d3b5e8-67db-4517-93a8-5ec485269635
Yes, I think about true, original waypoints stored in device (in any ciq applications, including watchface), syncing with basecamp etc. Not like this "creative solutions" who need battery drain in internet connection, and store ways and points in cloud.
And about _shared waypoints_ between oryginal applications in firmware and ciq - dwmap and hike don't can this.
Ok, long term, yes, undestund, I ask in 2017.
