Hello gents,
and thank you for reading my posting first!
I have an 898c HD SI in use and have been updating the software according the recommendation of my "Support account" at humminbird.
However, that was on Wednesday last week and since then I have done some tracks on the river Danube for establishing my private depth card. Since I updated the software it is not possible for me to import/ convert the data from the SD- Card into a Dr. Depth file, I am getting always the messages "No data found" or "Wrong beam, buddy!".
I have done some test- tracks with several different settings in the last few hours, nothing is working any more with Dr. Depth, no matter what beam is chosen on the Sonar (200, 83 and 200/ 83 kHz settings tried).
So now I want to go back to 6.490 version, downloaded it here and copied it to my SD- card. The card is plugged in the unit as on Wednesday when I did the upgrade, but the unit does not react to the lower software version. What am I doing wrong?
I have searched the board here the last two hours and did not find anything, maybe I am just blind
Thanks in advance for your help,
Best Regards,
Matthias
