Hi Folks…
Been away from this for around 8 years now and realize much has changed. My son and I are getting back in and just purchased a boat with the subject device. I plan to fish TN, KY, AL and GA. What is the best card I can get to load? Also any additional info on this unit is welcome. Getting started here and welcome any advice. The boat is also equipped with line and hookup at the front that works with the dash unit. So looking at adding a unit next to the trolling motor. Again, welcome any insight on this. Much appreciated.
