Command and control

Clarion's watertight MW4 remote control keeps you in command of your boat's stereo system. You'll be able to change sources, switch radio bands, and also adjust the volume, track selection, toggle play/pause and more — all while checking out your changes on the built-in 2.8" color LCD display.

This remote works with a variety of Clarion receivers, and you can use it to replace Clarion's MW1 and MW2 remotes. If you own a larger boat, you can add up to three MW4 remotes to control a single Clarion marine receiver.

Note: The MW4 remote comes with a 1-foot cable, so you'll also want to purchase Clarion's 25-foot extension cable.

  • 2.8" color LCD screen

Nice Remote

Written by: Reviewer from Georgia on September 5, 2015

Crutchfield Customer Review (What's this?)

Note that this rating is based on the MW4 operating an older Clarion CMD6. Using this remote with Clarion's current marine head units may unlock its full potential. Functionally, the MW4 is no easier or more difficult to use than the MW1 & 2. The color screen has a blue background. The title data or menu data displayed on the screen is very small and only uses a third of the available screen space. The lack luster visuals of the screen and the fact that the functionality is exactly the same as Clarion's less expensive remotes are the reason for the 3 rating. Again, I am grateful that the MW4 operates with such a wide range of Clarion's units and using an up to date head unit may be the ticket for its full potential.

Pros: Good basic functionality to control your head unit remotely. Easy to install Good looks

Cons: No better functionality than Clarion's less expensive remotes Lack luster display (using with an older Clarion CMD 6)

Not ready for prime time

Crutchfield Customer Review (What's this?)

It was hard to find information on this product before purchase so I took a chance and just ordered it. The product is very disappointing and appears to need work on the firmware. The interface looks nothing like the screenshots shown on the box or Clarion marketing materials. You basically get the same display and functionality as with their MW1 remote (which this was going to replace). Also the interface is Very sluggish. Turing the volume knob has a delay and the screen is slow to update. Meta data titles still scroll in a small portion of the screen instead of taking advantage of the full width. I figured this remote would make scrolling through SiriusXM channels and iPOD interface songs much easier. Nope. Works the same as their other remotes. No listings, just one song at a time. Needless to say I will be returning this.

Pros: No pros over their MW1 remote.

Cons: - Sluggish interface - No instructions included - Interface looks nothing like screenshots shown on marketing materials

Product Research


Wired Marine Remote: With Clarion's MW4 wired marine remote, you'll be able to control your compatible Clarion marine head unit at arms-reach.

Compatibility: The MW4 wired marine remote control is compatible with select Clarion marine head units (as of 11/4/2015).

  • CMV Series: CMV1
  • CMD Series: CMD6, CMD7, CMD8, CMD9
  • CMS Series: CMS1, CMS5
  • M Series: M303, M309, M502, M505

Note: Up to three MW4 remotes can be installed to one Clarion marine head unit.

Marine Tested: The Clarion MW4 has been designed and tested to hold up to the harsh marine environment.

  • Meets or Exceeds ASTM B117 (Salt/Fog Exposure)
  • Meets or Exceeds ASTM D4329 (UV Exposure)
  • IP66 (Dust/Water Ingress Protection Rating)

2.8" Optically Bonded LCD: The MW4 wired marine remote control features a 2.8" color optically-bonded LCD screen and white LED button illumination. The LCD screen will show source selection, song/artist information, and menu settings.

IR Repeater: The MW4 features a built-in IR repeater, so it can work with your Clarion marine head unit's wireless remote control.

Wiring: The attached 11" cable on the MW4 connects to the back of your Clarion marine head unit. Because the attached cable is only 11" long, in most cases an extension cable will be needed (020MWRXCRT, sold separately). Up to three extension cables totaling 75' can be daisy-chained together.

Note: The MW4 can be used in conjunction with Clarion's MF1 marine RF remote control (020MF1, sold separately). This type of setup requires a proprietary Y-adapter (020MWRYC, sold separately).

Surface Mount Bracket: The remote comes with an aluminum surface mount C-clamp. The remote mounts to the front of your mounting surface, while the mounting bracket mounts behind the mounting surface. The bracket attaches to the back of the remote via the included hardware and sandwiches the mounting surface in between the remote and bracket. You will need to drill two 0.1875" screw holes to attach the bracket to the remote, and you'll will need drill out a 0.8125" (in diameter) opening for the wired remote's cable to pass-through.
