I just sent in a 365 i in for repair, after having a month of trouble 1st day out on the yak in the sierras it "koncked" out, how old is it? go to humminbird.com and send it to the address...they have about a week turn around and it may not cost anything, depends...but I think I will go with
Garmin next or Lowrance because of Humminbird connection issues
