I own a Classic 22 (spring purchase) and would like to install a depth finder, possibly a split screen with GPS. Is there a way to accomplish this without messing up the classic interior styling? I have seen some classics with reworked dashes and indash flashers installed. I am not planning to rework the dash and do not want to drill any visible holes either. maybe a styled bracket mounted to the rear of the dash and a thru hull transducer? Any help is greatly appreciated.
