I presume youre talking NMEA 2000. Its no big deal to install yourself with a just a little technical aptitude. I think BCB prefers not to because of all the previous issues with the LowranceNet Ts, which I experienced myself during day 1 of the OI this year but luckily got the Lowrance reps to swap out all the Ts on my boat in the hotel parking lot that night. Using the Maretron/Molex connectors and components rather than the more cheaply made Lowrance ones (even the red ones) I believe will alleviate most of these experiences though. NMEA 0183, forget it. That still needs to be wired up custom depending on what the exact units and needs are.Just my $.02.Deke[font="]Deke[/font]
