I want to view the fishfinder on the TZT14 from a remote location. I have a used boat with TZT14 (from 2018) and followed the manual to set up a local wifi network and connected to my iphone (and Ipad) to view the TZT remotely. I am able to connect via the available apps on the iphone and ipad to the network and see the instruments and other data. However, on the "fish" option, I only see a display of the depth. No sonar reading from the fish finder. I would like to be able to view the fishfinder from the cockpit using the Ipad or iphone to confirm structure i=on the bottom and fish in the water column. Any help or hints appreciated. thanks.
