Excellent fit and functionality

This compact receiver fits into tight spaces, while the face features rubberized, backlit buttons that add visual punch and improve nighttime usability. The high-contrast TFT display gives you the information you need with just a glance, even in bright sunlight. The CMM-20 also works with Clarion's CMR-10, CMR-20, and CMR-30 marine remotes.

Made for life on the water

The front panel is IP66-certified to give you best-in-class water intrusion and saltwater protection. On the inside, rubber gaskets and integrated drainage channels keep water out. It's also UV-treated, so it'll stand up to broiling sunlight, too.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.
