yes, the 898 has the latest update. I called HB this morning and was told: On the 1198, go to the sonar screen, push the power button and from the menu turn the sonar "off" so the 1198 will use the 898 transducer instead of looking for one to be connected directly to the 1198. I will try that later today, might give me an excuse to jet outa my shop and get on the water!! Hope it works though, the 1198 is like watching TV the screens so big. I was also told it doesnt matter the order in which the units are started, and do not have to wait for the 898 to fully load before the 1198 should recognize the ethernet.
