The WM-4 Marine Weather & Audio Receiver is a device designed to provide live, up-to-date weather information and forecasting, as well as access to SiriusXM satellite radio service, for marine multifunction displays (MFDs) from Simrad, Lowrance, and B&G. It aims to enhance safety and enjoyment on the water by delivering comprehensive weather data and entertainment options.
The primary function of the WM-4 Receiver is to deliver SiriusXM Marine Weather services to compatible MFDs. This includes premium weather content such as current weather reports, NOWRad® nationwide high-resolution weather radar imagery, and high-resolution Sea Surface Temperature images. This information can be overlaid directly onto raster and vector charts on the MFD, assisting in navigation and identifying fishing hot spots.
In addition to weather services, the WM-4 Receiver offers access to over 150 channels of SiriusXM satellite radio service. This audio feature is optional and can be added to the marine subscription at a discounted rate. The audio output is an RCA-style Left and Right audio connection, which can be connected to an auxiliary (AUX) input on a third-party external audio system.
The device operates by receiving digital signals through a SiriusXM SRA-50 type-approved antenna. It then processes this information and transmits it to the MFD via a network connection. A GPS receiver, either internal to the MFD or an external unit, is required to provide position information for weather, chart, and radar applications.
The WM-4 Receiver integrates seamlessly with compatible Simrad, Lowrance, and B&G multifunction displays, allowing users to view weather information directly on their charts. The ability to overlay weather data enhances situational awareness for safe navigation and strategic decision-making, especially for activities like fishing where sea surface temperatures are crucial.
The optional SiriusXM satellite radio service provides a wide range of audio entertainment, making long trips more enjoyable. Users can subscribe to both marine weather and satellite radio packages, often with a discounted rate for the audio service when combined with marine weather.
The installation process is designed to be flexible, offering various mounting options for the antenna (surface mount, low profile surface mount, pedestal mount, extension mast mount, and rail mount) to suit different vessel configurations and ensure optimal signal reception. The receiver itself is water-resistant, though it's recommended to mount it in a sheltered location to avoid direct contact with water spray.
The WM-4 Receiver is designed with minimal user maintenance in mind. It contains no user-serviceable components, meaning all maintenance and repair should be referred to authorized Navico dealers. This approach ensures that any issues are handled by trained professionals, preserving the product's warranty.
For optimal performance and longevity, proper installation is crucial. This includes adhering to EMC installation guidelines to minimize electromagnetic interference, ensuring correct grounding, and protecting the power supply with a suitably-rated fuse or circuit breaker. The manual provides detailed instructions for cable identification and connection to prevent common installation errors.
In case of operational issues, the device features LED indicator lights (Power LED and Network LED) that provide visual cues about its status, aiding in basic troubleshooting. The manual includes a comprehensive troubleshooting section that correlates LED patterns and MFD messages with potential problems and solutions, such as checking cable connections, antenna mounting, or subscription status. If a cable is damaged or out of spec, replacement is recommended through authorized dealers.
For subscription management and activation, users can access online portals or contact SiriusXM directly via phone, with separate contact information provided for US and Canadian subscribers. Activation signals can also be resent if needed.
The product is built to conform to appropriate Electromagnetic Compatibility (EMC) regulations, and the use of specified cables and suppression ferrites (if fitted) is important for correct EMC performance. While waterproof, it's advised against subjecting the unit to commercial high-pressure washing to prevent water ingress and potential equipment failure.
