Solix 15 Splitter Cable Question

[BassnPhoenix920]

Purchasing for the helm a Solix 15 G2 with Chirp, Mega Si+ and XP 14 HW Solix Dual Spectrum Chirp in-hull transducer. I am trying to find out what splitter cable do I need and if I need anything else?

I would suggest you add a GPS antenna at the transom so GPS and Sonar is at the same place. Waypoint accuracy and contour mapping accuracy.
Either the AS GRP which is GPS only or the AS GPS HS which is a combo GPS and Heading sensor.
