Sony's RM-X55M/Q2 wired marine remote control lets you manage your water music from a convenient spot — without exposing your Sony stereo to the elements. When connected to a compatible Sony UniLink stereo, this water-resistant remote can handle track selection, fast-forward, rewind, volume, and source selection.

The remote comes with an 18-foot extension cable, so you can mount it in a variety of locations. Store your stereo safely inside the cabin and let this UV- and salt-tested remote deal with the sun, salt, and spray. Warranty: 1 year.

Product Research



Compatibility: The RM-X55M/Q2 is designed to work with Sony's UniLink control marine receivers that are compatible with Sony's wired remote. The included UniLink "Y" adapter allows you to connect this unit and another UniLink source (CD changer, Satellite or HD Radio, and iPod) to a compatible head unit.

Display: The display shows source and mode information, satellite radio information, and RDS and CD text information (if supplied by the head unit).

Water Resistant: The remote is water resistant, so it is ideal for use on boats, where a head unit needs to be kept dry, but you need to control it from a damp remote location.

Mounting: The RM-X55M/Q2 requires a 3.155" diameter round cutout. It's held in place using the included mounting bracket. The mounting depth is 1.4375".
