Correct upgrade e7D
Hi,so far I've had e7d with internal transducer P58, and now I just installed CP450 and two transducers 1kW B175 L and B175H 20 degrees and connect to e7D. Can you tell me the exact procedure to setup e7d with CHIRP sonar. Should be CP450 disconnected from the mains before a fix the e7D.See More
