I'm about to do a weekend trip into Death Valley, which has no cell coverage. I've created 2 routes, 1 for the trip to Death Valley and 1 for a Death Valley loop. The 1st route will start off with cell coverage while getting to Death Valley, and the 2nd route completely in Death Valley with no cell coverage.
So to my question - on my first route getting to Death Valley, do I need to stop and specifically turn on Offline Navigation before getting into Death Valley?
And for my 2nd route without any cell coverage, I assume I'll definitely need Offline Navigation turned on?
Is this all correct? Thanks!
