Control your tunes from the transom With this transom remote connected to your Wet Sounds WS-MC1 marine media center, you can control your entertainment while you're enjoying a swim. It connects to the WS-MC1's black box unit via the included 23-foot MC-TR EXT cable and gives you the ability to adjust volume and choose sources when you're nowhere near the helm. This compact gauge-style remote doesn't take up much space, but it gives you a lot of ways to enjoy your music. You'll be able to control the radio, connected Bluetooth and AUX devices, and even your Pandora playlists. It'll also control the main volume and individual zones. You can connect up to three of these remotes to your black box using the MC-TR Y cable (sold separately).
