    Ultrex - Humminbird 859 - Universal Sonar not working

    I installed an 80/24 Ultrex on my champion a couple weeks ago and took it out last weekend - everything worked great except I couldn't get my transducer to work and display sonar on my 2015 model 859 - i finally changed my source to the rear transducer i have networked and fished the rest of the day like that. Any suggestions on where I should start troubleshooting? Also I used the MKR-US2-8 Humminbird 7 pin Adapter Cable to attach my US2 wire to my unit.

    Did you change the transducer type in the sonar menu?

    Pretty sure I did. I will go back and look - what should it be set to?
