Going to challenge that thought . lol I bought a boat that has livescope . I have a 93 SV UHD , model that he had one unit running livescope , sideview , the works . I added a 93SV that is not UHD to run livescope . Here comes the Question ? what units can I replace to run livescope ? Will all units that have are livescope compatible work ? Wanting to go up in screen size .
