GPS Antenna
$365.00
- Type: A dedicated antenna designed to receive signals from Global Positioning System (GPS) satellites. This specific part number is engineered for precise compatibility with the navigation and infotainment systems in later model year Maserati GranTurismo vehicles.
- Function: The primary functions of the GPS antenna are crucial for modern vehicle functionality and driver convenience:
- Navigation System: Provides the necessary satellite signal input to the vehicle’s navigation unit, enabling accurate positioning, mapping, and route guidance.
- Location-Based Services: Supports other vehicle systems that rely on precise location data, such as telematics (emergency services, stolen vehicle tracking) and certain infotainment features.
- Time Synchronization: GPS signals also provide extremely accurate time data, which can be used by the vehicle’s internal clock and various electronic control units.
- Components: Typically consists of the antenna element itself (often a ceramic patch antenna), an integrated low-noise amplifier (LNA) to boost weak satellite signals, and a coaxial cable with a specific connector designed to plug into the vehicle’s head unit or navigation module. For Maserati, it might be a compact, self-contained unit, sometimes integrated into a larger roof-mounted “shark fin” antenna, or hidden within the dashboard/rear parcel shelf.
- Location: The exact mounting location can vary, but commonly found in areas with an unobstructed view of the sky, such as under the dashboard (e.g., near the windshield), on the rear parcel shelf, or, most visibly, integrated into a roof-mounted “shark fin” antenna.
- Material: Encased in a durable, weather-resistant plastic housing, with sensitive electronic components internally designed to withstand vehicle vibrations and temperature extremes.
- Design: Precisely tuned to receive GPS L1 band frequencies () and engineered for optimal signal reception even in challenging environments, ensuring reliable navigation performance for your Maserati.
The GPS Antenna, identified by Maserati Part Number 89251246, is a vital, though often unseen, component in your 2017+ Maserati GranTurismo Sport Auto. It serves as the direct link between your sophisticated vehicle and the global network of GPS satellites, providing the fundamental location data that powers your navigation system and other critical telematics features. In an era where precise positioning is key to convenience and safety, the reliable function of this antenna is paramount.
The core function of this antenna is to receive the faint radio signals transmitted by orbiting GPS satellites. These signals, once processed by your Maserati’s navigation unit, allow the system to accurately determine the vehicle’s precise latitude, longitude, and altitude. This real-time positioning is the foundation for all modern in-car navigation, enabling turn-by-turn directions, real-time traffic updates, and point-of-interest searches. Beyond just navigation, a properly functioning GPS antenna also supports other location-based services within your Maserati. This can include emergency assistance features, stolen vehicle recovery systems, and precise clock synchronization for various vehicle electronics. For a high-performance luxury vehicle like the GranTurismo, accurate and reliable navigation is an essential part of the driving experience, ensuring you can confidently reach your destination.
Given its exposure to the environment and its delicate electronic nature, the GPS antenna can be susceptible to various forms of failure:
- Signal Loss or Degradation: This is the most common symptom of a failing antenna. It can be caused by internal electronic failure, damage to the antenna element, or issues with the coaxial cable connection.
- Physical Damage: If roof-mounted, the antenna can be damaged by car wash equipment, impacts with low-hanging objects, or vandalism. If internally mounted, damage during other dashboard repairs is possible.
- Water Ingress: Compromised seals (especially on roof-mounted units) can allow water to enter the antenna housing, corroding internal electronics and leading to failure.
- Internal Component Failure: The integrated low-noise amplifier (LNA) or other internal electronic components can fail over time, resulting in a weak or non-existent signal.
- Connector Issues: The coaxial cable connector can become loose, corroded, or damaged, interrupting the signal transmission.
Symptoms of a failing GPS antenna are usually related to navigation system performance: “GPS signal lost” messages, inaccurate vehicle positioning on the map, the navigation system freezing or failing to load maps, or slow satellite acquisition times. In some cases, other location-dependent features might also malfunction. Replacement of a GPS antenna typically involves accessing its mounting location, disconnecting the coaxial cable and any power/ground wires, unbolting the old antenna, and installing the new one. Depending on its location (e.g., roof vs. dashboard), this can range from a simple to a more involved process requiring removal of trim panels. Ensuring a secure and waterproof seal (for exterior antennas) is critical for longevity. While often a plug-and-play component, proper routing of the coaxial cable to avoid interference and ensure optimal signal reception is important.
For your 2017+ Maserati GranTurismo Sport Auto, ensuring the integrity and optimal function of the GPS Antenna (Part Number 89251246) is paramount for maintaining reliable navigation, access to location-based services, and the cutting-edge technological experience expected of your Italian luxury sports car. Replacing a faulty antenna with a genuine Maserati part helps restore full system functionality and your peace of mind on the road.
