Navigation: We navigated using paper road maps of each state. So we had a Washington, Oregon, Nevada and California. When driving we used the OSMAnd GPS App running on Betsy's Samsung Galaxy S9. OSMand is definitely worth knowing about, see Osmand (Open Street Maps for Android) for details. It allows you to download entire provinces and states in Vector format. OSMAnd isn't the best for actual hikes, for these we still use Backcountry Navigator (BCN).
