Do I Need Internet to View Charts in My Navionics Boating App?

An internet connection is required to log in to the app and download maps to your device initially. Once you have logged in and downloaded maps within the Navionics® Boating app they are resident on your device and can be accessed as a reliable tool for charts even when outside of cellular reception. The Satellite (Bing) and Terrain overlays do require an internet connection in order to be viewed.
