The DSM300 and GPS sensor do not shut off either when the main unit is off. So they would stay on all the time when the battery switch is on.
I use a spare panel switch for the DSM, the only component that I switch.
I think the seaTalk junction box has a power feed input too, also not switched.
With the exception of the DSM where I added a switch, everything else gets a position off a new fuse panel that is fed when the battery switch is on. When I leave the boat I turn off the battery switch, which kills everyting else, before though, I turn off the head unit. I have not read the ship's battery switch can't be used to kill power for any device which doesn't have it's own on/off button (namely DSM, GPS sensor, and Seatalk box).
Have you found a location for the DSM ? Doesn't need to be near head unit.
Alternately on the radar scanner, you can come out the back and position a clamshell fitting over the box and and come in that way, caulk the cable entrance fully under the clamshell.
