Overview Garmin GPSMAP 3005C Network Chartplotter
The Garmin GPSMAP 3005C Network Chartplotter is a dedicated marine chartplotter built to serve either as a standalone navigator or as part of a Garmin Marine Network installation. Its 5-inch VGA color display, WAAS-enabled GPS sensor, and broad waypoint and route handling make it a practical navigation hub for smaller to mid-size helms.
This model also supports optional weather and sonar add-ons, which makes it useful for boaters who want to keep a chartplotter-led system rather than moving to an all-in-one touch display. The unit is designed around hard-key operation, proven chart card support, and durable marine construction.
Key Features
- 5-inch sunlight-readable VGA color display keeps navigation data visible in bright helm conditions.
- WAAS-enabled 12-parallel-channel GPS sensor supports accurate positioning and reliable route work.
- Built-in Garmin Marine Network allows the unit to connect with multiple displays and sensors in a broader system.
- Support for optional GDL 30/30A weather/audio and optional GSD 20 remote sounder broadens system capability when needed.
- Worldwide basemap, Garmin BlueChart support, and MapSource compatibility give the unit flexible chart options.
- 4,000 waypoints, 50 reversible routes, and 10,000-point track logging support serious trip planning and track review.
Applications
- Dedicated navigation stations that need a reliable chartplotter with hard keys and WAAS positioning.
- Boats expanding an older Garmin Marine Network with additional screens or chart stations.
- Operators who want optional weather and sonar integration but still prefer a chartplotter-first setup.
