That’s correct, the typical installation for HDS is as shown in the image I’ve attached. Before I figured out that I didn’t need this server hub, I planned on installing the system with small wiring plugs for quick removal, if necessary. As far as I can tell from their website, the unit will only interface with the Gen 2 or 3 from the HDS series (even though the Gen 3 doesn’t need the server).

The server hub connects to the NMEA0183 output on your locator, and also needs to connect to a power source on your boat. That’s all. The phone or tablet connects wirelessly through the WiFi signal emitted from the server hub. Which HDS model do you have?
Sorry for the delayed response. The SonarServer will wirelessly transmit depth and GPS data through the NMEA0183 output to a device that has the Navionics App. I do not use any cell data for this operation. I have not used this server at all, but its the same procedure I use with my HDS gen 3 units. Just find the server in your wifi listings and connect to it. The Navionics map with update the contour lines automatically as you drive along. This server doesn’t allow for the screen sharing like the Lowrance hub does. If you’d like more information on the unit, I’d be happy to try and answer further questions. You can also visit http://www.sonarserver.com
