@Doug-Robinson Thanks Doug. I had not previously downloaded any maps. I'm a new MRA user, and this was my first time experimenting with the map(s) download function.
The HERE download Update above the region downloads confused me because it doesn't make sense to generically first update every HERE map across the world. Or maybe there is something else to it not outlined in the documentation. I live in California, and I only wanted to first start with my local map. I did go ahead and download the California map and went out for a quick ride to test offline navigation out.
Again, maybe I'm making something of nothing. I just want to understand what generic the HERE map download (at the top) actually does.
