GPS only required for real time route navigation. Optional Real time AIS, Tides and Weather information require an active internet connection. Real-time route navigation requires a GPS location. iPhone devices and iPads with a cellular modem already have a built-in GPS, even if they do not have an active service plan. If you have a WiFi-only iPad or iPod you will need an external GPS receiver to enable navigation. Inexpensive 3rd Party units are available to add these accurate location capabilities to your device via bluetooth. Please note that continued use of GPS running in the background can dramatically decrease battery life.
