@W0LFB3AT5: Just as an example, last time I navigated us about 40km out into the country side it took a whooping 1.35mb of cellular data, over 2h of driving there and back.

@NotMeNotYou: well I rarely use my phone maps for whenever I'm traveling something a bit farther from where I live. And yet I barely use it to get home. All I had to do was retrace my steps and waste less data on it.
