Just curious, for us Canucks that have terrible travel roaming packages:

- If I were to purchase an ipad (non GPS) could I still use Navionics (i.e. only use the charts for planning purposes if there is no GPS information)?

- If I were to purchase a GPS enabled iPad or use the Navionics app on a smart phone, does the Navioinics app use Data or just GPS location information?

To give some insight, roaming plans from Canada typically only include up to a 100MB per day.

Thx!
