Freedom to Roam
For example, Raymarine (raymarine.com) has embedded Wi-Fi and Bluetooth technology into its e- and c-series MFDs. This allows viewing and controlling of a navigation display and virtually every sensor and device connected to it, including GPS, chart plotter, radar, fish finder, engine instrumentation, video cameras, AIS and more, right on a smartphone or tablet. This usually involves downloading the appropriate mobile app to activate the remote feature. The Raymarine Viewer is a free app that replicates the MFD screen on a tablet. Two other apps offer complete operational control of a display from your tablet (RayControl) and your smartphone (RayRemote). These apps are priced at $50 each.
