970 Maps doe not function while on a run after loading a course and hitting navigation.
Note that using the standalone Maps feature alone is relatively slow, but once you are on your run, i assume because there is other processing going on, the maps feature is so delayed as to make it useless.
The issue here is typically the WHOLE purpose of the navigate feature is you are in a new area and are using to help you not get lost. But if you can not pan/zoom and see where you are without stopping your run and waiting for it to load it is not functional.
For software engineer reference I only have 2 data screens on, and the "workout" adds a 3rd automatically. So NOT a lot of extra data is being processes here.

Can Garmin "Cache" the area better?
