ok I have a transom mounted 360 and it worked great once or twice but since then it won't work.
The problem is it shows up and on my units and makes the sweep but everything inside the circle is black.
I called humminbird and was told to update the software but I still have the same problem.
I have a 1199, 998, iPilot and 360 all interlinked.
Tonight I downloaded the 360 software on the 998 card and ran the 360 only to the 998 with no luck. I also swapped the cable from the 360 to the 998 and still no luck.
The accessory test shows the 360 is connected and the software is up to date.
Any thoughts before I send the 360 in?
