I have had and still have on occasion that problem. What works every time for me to instantly fix it is increase or decrease the depth/distance on one or both of the down/side while moving, and my unit instantly pops out of being stuck. Once its running again, I switch it back to auto depth. The problem with my unit was due to the unit resolving super shallow or fast speeds, or very abrupt changes in depths while in auto depth/distance mode. Using reg sonar with the down and side made it worse. I hardly ever have this problem any more after re-positioning my transducer a bit higher. As an added benefit, I can read bottom now up to 33 MPH. Not using reg sonar I think has helped resolve this issue also. I didnt stop using the reg sonar for this purpose, I just have no need to use reg sonar on my console unit.
