Know before you buy
The main processing unit is designed to be mounted out of sight, such as behind a dash or in a storage compartment. This keeps your helm clean and uncluttered, leaving only the sleek 4.3-inch controller visible on your dashboard.
Yes, the CMS5 features dual-zone audio control. This allows you to adjust the volume levels separately for two different areas, such as the cockpit and the swim platform, from a single source.
The controller carries an IP66 rating, meaning it is fully protected against powerful water jets and harsh marine conditions. The optically bonded screen also prevents fogging and moisture buildup, ensuring clear visibility in direct sunlight and wet environments.
The CMS5 is SiriusXM-ready, meaning it is compatible with the service. However, you will need to purchase a separate SiriusXM Connect Vehicle Tuner and a subscription to receive satellite radio signals.
Yes, the unit includes a dedicated rear-vision camera input. This allows you to view your camera feed directly on the 4.3-inch color display, which is particularly helpful for docking or monitoring your surroundings.
The USB port supports playback for MP3 and WMA audio files. Simply plug in your compatible flash drive to access your digital music library directly through the receiver.
