Data Insights

Wired Ethernet connectivity on the MS-ERX400 eliminates the latency and dropout issues common in wireless marine audio remotes. The display clearly renders song metadata, playlist position, and multi-zone status simultaneously, allowing drivers and passengers to manage audio without distraction.

Install the remote by running the single Ethernet cable from your Apollo Series stereo head unit to the desired location on your boat. Connect the cable to the remote's Ethernet port; power draws from this connection automatically. Navigate your music library using the rotary knob, press to select tracks, and use the physical buttons below the display for play, pause, rewind, and forward functions. Access audio zone controls and settings through the on-screen menu to customize playback for different deck areas or cabin spaces.
