Did my survey and everything looks great at this point. few things came out before the survey report. SR310 - 2008 with 6.2 seacore and AXIUS. Engine data not showing in GPS. newly installed Garmin 74CV + Transducer. How do i get the data form the Smartcraft to the display on the garmin? Newly installed Marine Radio - GX 1600 Newly installed TV antenna Newly installed Garmin GPS 19x HVS Any additional thought would be much appreciated.
