Two things to consider on smartphone/iPhone apps.
1. If you lost cell phone signal you do not have real time data.
2. When using map apps, unless you have a unlimited data plan, you are being charged for data usage.
I have been told you can download the route, but I prefer a Garmin 760LMT
1) You don't have real time data with a dedicated GPS either in that case...or when you are in cell range.
2) If you are worried about data, you can download the area ahead of time and it uses negligible data.
