Great radar, this is a kit unit, meaning it can link directly to the radar. In order to get chart overlay you will need the Lowrance point 1 compass, and if you want the MARPA function you will need the RI10 navico radar interface box and the simrad RC42 rate compass. plus 4 cables to connect to NEMA 2000 Network and adapt from the radar interface box .
Plug and Play, minimal time to set up. Worked great with NSS12
Removed old analog system from my boat and used this radar unit to go with Simrad NSS12 and NSS9. Easy to install and fire up. Cost effective way to go for this kind of upgrade.
