There are two versions of the 360. One is transom mounted and looks like a Talon shallow water anchor. The other is designed to clamp to the upper shaft of a Minnkota cable steer trolling motor.
Both have been reduced $500 MSRP so the transom model is $1500 and the bow model is $1000 now. Some dealers sell them for less.
It works with the above listed models plus all of the current models of the 800, 900, 1100, and ONIX units including Side Imaging, Down Imaging, and 2D models. That's 19 different models.
There is no black box for the connection, it is either connected directly to a display via Ethernet or shared via Ethernet with an Ethernet switch to as many units as you want.
I have the bow model connected directly to my bow 1198c SI Combo.
I have a Motor Guide trolling motor and got a shaft adaptor from Transducer Shield and Saver to make that attachment.
The images are not as sharp as Side Imaging since the transducer crystals rotate. It does a lot better than using an imaging transducer on a trolling motor and turning the motor to scan.
It can also be used for Side Imaging just by selecting the Side Imaging view. When you do that, the 360 stops rotating and orients the two crystals left and right just like a Side Imaging transducer.
Some examples of stuff I have seen with my 360:
