Frequently Asked Questions

Where can I see detailed help about PathAway?
Start with the User Manual of your version of PathAway such as the PathAway Professional for Android document.

In iNavX, can I switch between measurement units?
Yes, unit switching was included within iNavX in early 2013; if necessary, update your iNavX software version.

For iNavX, can multiple weather forecast types be stored in memory at the same time? Is another Internet connection needed each time a new forecast is fetched?
The web service model implemented in iNavX retains one type of forecast at a time. A different forecast type requires another brief Internet access session to fetch data.
