I'm interested in connecting a Raspberry Pi 4 to my boat's audio system. I stumbled upon a boater's forum where a member was reviewing a Pi HAT, called PICAN-M. The PICAN-M allows the Pi to be powered by the NMEA 2000 connection.
What I'm interested in understanding is if anybody here knows if I could simply run a NMEA cable from the back of my Fusion Entertainment MS-RA70NSX head unit to this Pi 4 / PICAN-M solution and have it be powered? The goal would be to setup a media server with Rune OS and improve overall sound quality (maybe even with leveraging a USB-powered DAC) versus a traditional Bluetooth connection.
Thank you and please advise.
