Ayuh,.... Welcome Aboard,.... You'll need to ID the Hummin'bird model, as Cobalt didn't build the sonar...
Shouldn't the depth finder sit in the empty bracket on top of the dash?
No just like he said the LED panel all the way to the right on the instrument cluster. Might be a 'Lowrance', unless you can see some specific markings. Is that toggle switch related to the Depth Finder? I am wondering if it was added or replaced from the original :noidea:.
Anyway, the quickest way to find out what it is would be to pop the instrument panel out for a look at the back side
