Last week I updated my Helix 9 mega si G2N to 2.180. Today at the lake I had lost temperature.
Checked out the System Status and temp was not connected. I have checked out the cable and connectors. No bent pins. Transducer in use is the mega trans. I have reset everything to default. Still no temp. Am I missing something here, before I set up an I am upset session with humminbird?
