I have I have two 998c hdsi units and bow 360. The bow 360 works very well once you learn adjustments, but both of my units are 3 months old and have the latest downloads and neither will record the 360 images. They record the side and down imaging well ,but if you try recording the 360, all you get on any view is a black screen,except with the 2 d sonar it is always right. The side imaging and down imaging work when ran off of the side scan transducer, but if i use the 360 transducer they are just black with no picture. Sometimes the 360 video image will be their but it is like a broken blurry snapshot that never rotates. Can someone explain what is happening? In the manual and humminbird techs say the 360 is supposed to play back along with all the other views. Like I said I have two 998 units and both are doing the same thing. We went back to basspro and they hooked another 360 unit to both the 998.
