Good morning,
I have the 998c H from April of 2010. I saw on line that the software had been updated. I have tried several times to download the 5.4 software and then upload to my 998c unit. I have been on the phone with Humminbird support three times.
Help.
I go to H support and log on. My account my profile and then 998c. I down load to H pc on my computer. Message download correct. I move the download to the sd card. Message. send done/correct. I take the sd to my unit. I power on; I use menu to restore defaults. I put in the sd card. According to Humminbird support, I should then see an on screen message to upload from sd card to 998c unit. No message comes up on the screen. I checked the sd card to make sure it is not locked. It is open to be written on and uploaded from. I have tried two sd cards.
Has anyone else had this difficulty?
Joe
