While browsing through the menu on my 93sv I remember seeing a way to control music through the unit. At the time it wasn't a big deal since my boat had an am/fm/usb radio. Fast forward a month and that boat is on its way to the boneyard. I want to rig my new boat once and be done, so I bit the bullet and sold my brand new 73sv and bought another 93sv for the bow. Id like to be able to use my console graph to run my music through but have no idea what I need to set it up. I won't buy another subscription to xm (getting ready to cancel the sub. in my truck) so I want to be able to run am/fm/usb/bluetooth. Is this possible or should I look at just buying another radio to fit in the flasher hole.
