BrewKid--good to hear from a C Dory owner's positive experience with the Fantom!
I notice you are using the Garmin 942xs. Unfortunately not all of the Garmin chart plotters work with the Fantom.
list below:
1022, 1022xsv, 1042xsv, 1222, 1222xsv, 1242xsv, 722, 722xs, 7407, 7407xsv, 7408, 7408xsv, 7410, 7410xsv, 7412, 7412xsv, 7416, 7416xsv, 742, 742xs, 7607, 7607xsv, 7608, 7608xsv, 7610, 7610xsv, 7612, 7612xsv, 7616, 7616xsv, 8208 MFD, 8212 MFD, 8215 MFD, 8417 MFD, 8422 MFD, 8424 MFD, 8500 Black Box, 8530 Black Box, 8617 MFD, 8622 MFD, 922, 922xs, 942, 942xs
My 1041xs will not work with it. Many of "Last years" MDF will not work--but the 942 xs, which is a touch screen, seems to have a large number of features!
