Humminbird sent me a replacement unit, I repeat, a replacement unit not a new unit like the one I purchased from Bass Pro Store. Anyway the replacement unit is in need of repairs also. To make a long story short Humminbird wanted me to send the replacement unit back for repairs then they would send it back to me. I said no, I will not send it in until I get a working one in my hands. You know like the one I should have got when I spent $2700 for at the store. Not to count taxes and iPilot link and a Minn Kota trolling motor that could accept the iPilot link. So now I'm waiting for another onix head unit. Way to much money for these things, to have them not work on several units. Hopefully 3 times is a charm. Very disappointed.
