My dad said this didn't work with his transducer or something and asked me to sell it on eBay. Looks like he had installed it (see side pics) but the screen and buttons look perfect. Probably has been sitting in his boat house for years. Please see pics for condition and what is included. He didn't give me the mounting bracket, but it looks like you can buy one on eBay or Amazon.
