I have a Humminbird 798 with SI/DI/2D on my bow so I could link it to my dash 898 with the same features. To get the features of that unit one has to run the Humminbird transducer and to avoid having cord wrap that several people mentioned above just remove the head of the TM, disconnect a couple wires, remove the one bolt going through the fiberglass shaft and remove the remaining parts of the TM head unit. Slip the shaft all the way out of the base bracket and slide your new transducer cable into groove in the TM shaft (the groove/slot in the Terrova 80 shaft does nothing... maybe a structural strength thing but no other purpose). Use some shoe glue or something along that line to attach the transducer cord in the slot and done! Mine has been this way since January of 2012 and zero issues... Only one... The transom CSI transducer in the pictures isn't shielded as well as the Humminbird purpose built TM mounted CSI transducer and I got some interference. I eventually switched over to the Humminbird TM mounted transducer and all my inteference issues went away.
I also shortened my shaft length down to 54" a year or so later and a happy camper.
I would not own a boat without a Terrova or a TM like it. The cats meow of TMs!!!

If your bow isn't seriously heavy duty you will eventually start to do some metal damage up front... I had to do quite a bit of messing around to strengthen/re-enforce the bow of my boat to handle the Terrova 80. I have a bad habbit of using jack rabbit mode when out bass fishing on Lake Mead... Have the TM turned left or right and then hit the button that is some serious torque twisting the bow area in a un-natural direction.
All good years later after those things were done.
