Hey gang got my boat back yesterday from the dealer. One question, coming out of the back of the Co2 detector in the main cabin is a wire that has what looks to be a little infrared device attached to it. It is about two inches in length and is attached to the galley wall. I asked the dealer what this was for, they did not know. I cannot tell if this is for the AV system or is part of the CO2 detection system. I have a 2008 2565. What do you think it is??
