With the help of Lowrance's tier 2 customer support (same person the entire time) I spent over two weeks trying to make my Lives work with the latest update, they did the same thing as previous updates. The new Pros are working perfect with the same exact wiring as the lives and the same settings that were exported from the Lives to a card, then imported to the Pro's. The only thing that changed was one gimbal bracket, I upgraded the 9 to another 12. My Live units had an issue, hardware or software? I don't know.
This only my experience, I can't comment on others issues.
