I recently purchased a 2020 Z18 Pro with Hummingbird Helix 7 MSI on the console, Helix 7 MDI on the bow, Ultrex with MDI with iLink, and they are all connected to the HB ethernet hub. I cannot seem to get my console HB to graph at all. It appears I received a few upgrades that are not included in the 2020 Z18 Pro models, for instance ... my Ultrex came with the MDI Transducer, and the transducer on the console Helix is the transom mount "HW + MEGA SI 150" which apparently is the XNT-9-HW-MSI-150-T MEGA SI/DI Dual Spectrum CHIRP Transducer w/Temp. I am grateful for the unexpected gift ... however, I cannot seem to get it to function properly. I checked the cable going into the back of the console unit, and it is a Y cable. First question ... is there a thru hull 2D already installed in the 2020 Z19 Nitro Pro? Second ... why the Y cable? Third ... any cles why I cannot get SI/DI/2D to show good data while idle or at a stand still with motor off? Before this purchase, I was a Lowrance user, so please forgive my ignorance. I am an engineer, and I have tried everything from reading the manuals front to back as well as watched every YouTube video I could find. The Transducer that shows up in the sonar setup menu is "HW + MEGA SI 150". Any help would be appreciated.
