As title says, I can't seem to get a solid return with my Ai 3 in 1 2d sonar. My pd-wbl transducer works fine. I tried swapping the 3 in 1 and pd-wbl connections on the back and that didn't help. So instead of the 3 in 1 2d being bad on channel 2, after the swap it was bad on channel 1, and the pd-wbl on channel 2 was fine. I also did both a soft and hard reset to no avail. Also, after the resets the Ai 3 in 1 was not being recognized automatically. It was on the black connector. Does that mean my ducer might be bad?
See attachment. Pd-wbl 2d on left, and then switch source to 3 in 1 and that's what I get on the right.
