I have a Brand New Setup from a Lowrance LMS 520C. It is basically everything except the head unit, mounting bracket, knobs and manual. Someone stole my 520 from my boat while I was in Ingles buying some drinks, so I had to buy a replacement and now I have extra parts. I know that these parts will also work on the LCX-27C and LCX-28C
Transducer HST-WSBL Part #106-72
LGC 3000 GPS Module LGC-3000 Part #125-09
Power Cable PC-27BL Part #127-08
and Some other connections and brackets are also included and shown in the pics below.
I am selling for 250.00 and the price is firm. All these parts are Brand New. If you bought these parts individually from lowrance, they would total up to be more. PM if interested.
Thanks!
