You can go with a Garmin Fusion Apollo Marine Hideaway Stereo MS-WB675. You can then add an MS-ERX400 remote anywhere on the boat. They have these great ARX $50 remotes in white and black that you can put anywhere with no wiring. There is also an app that you can use to control it from your phone. However, doing this will completely replace the Connext sound system, and you will also need a new amp or two as the existing one has a proprietary wiring harness. You can continue to use the existing speakers in the boat and add more if you wish.
