Hi guy's. I have a Standard Horizon CP180 w/sounder box. Recently the sonar stopped working. It just reads 7' & never changes. The temp is working fine. The transducer is a P66 & I think that is working but not really sure how to check it. When I disconnect it from the sounder box I do get a message on my screen that it is not detected. I played with the settings & can't get to read. I hooked up a portable FF & the water temp reads the same or very close so that why I think it is working. The unit is about 5 years old & has been working fine up until a couple of weeks ago.
Any suggestions?
