I am going to post a few anomalies that I have found with the software relating to the 360. I doubt that Humminbird will have the resources to fix minor issues like these. Maybe this will help someone else who has the same problem.
I have an 1198 running version 7.09 at the bow and I have a 360 trolling motor mount running version 2.03 - both units running the latest software downloaded from Humminbird.com. This issue has also happened with previous versions of the software since I purchased the 360 last December. I always update to the most current versions.
Issue #1: When I power up the 1198 and give the 360 imaging time to come up, I expect to see the following views, in order: 360, 2D/360 combo, Map/360 combo. However, the 2D/360 combo box doesn't appear. To get it to appear, I have to turn off the sonar, then turn it right back on. The 2D/360 view now appears.
If I turn on the 1198 with sonar set to OFF and later turn it ON, the 2D/360 view appears.
Issue #2: When the 360 is on, sometimes the Map/360 combo box disappears. I have to reboot the unit to get it to reappear.
