Setting sat nav destination

I used my phone on the way home from work today, tried Apple Maps, I must say it’s very good, just wish I knew how much data it used…?

Can you not see it in your mobile data statistics ?

Apple may be a little different but last week I used Google Maps nav for about 10 hours of driving and it's used about 125 MB.

2 hours was on a saved map segment, the rest was long distance so may use more per hour with the extra map downloads, traffic info and (re)calculations.

Considering I’m asking about setting directions, how do I find my way to mobile data…🤔

Perhaps ironically, Google is your friend: 

To see how much mobile data you've used, go to Settings > Mobile Data or Settings > Cellular.

Full page that extract was from:

Use mobile data on your iPhone or iPad

As with Android the exact location or phrasing may vary with the version and device. But it's in there somewhere ...
