I swapped out an Elite 7 for an HDS 7 touch, retaining the transducer that was on the Elite 7. I now have 2D and DI using this transducer. I understand I have to have and LSS2 in order to do SI.
Two questions:
1. There is a 2nd transducer connection on the back of the HDS 7. Is that specifically for the LSS2? It is configured differently than the other connection where the current transducer is connected.

2. When I got the HDS7 I had to go in the system settings and select the ELite 7 transducer before the DI would work. Apparently the factory setting on the HDS 7 is different than the Elite 7. So....do I have to go in and select the LSS2 transducer in the menu for the SI to work and does this disable the setting I have for the DI and 2D.
What I am hoping is they are separate and I can simply switch between the 3 views once I have the LSS2 installed.

Thanks for your input.
