I forgot to include; the intercom and the Comm Nav were installed in Esmeralda when I purchased her in March 2021. They both worked great with out any issues. I pulled them because I did not need a Comm Nav radio and to install a Garmin GTR-200B. This radio has a built-in intercom and it freed up a panel space to install an EI 5P-5L fuel flow monitor (at a future date).
