Garmin GPSMAP 1040xs Chartplotter Fishfinder

Overview Garmin GPSMAP 1040xs Chartplotter Fishfinder

The Garmin GPSMAP 1040xs Chartplotter Fishfinder is a larger-format Garmin combo for operators who want both charting and sonar on a 10-inch keyed display. It comes preloaded with U.S. coastal BlueChart g2 mapping and U.S. LakeVu HD charts, giving it useful coverage for both inland and coastal navigation out of the box.

This model supports a broad range of compatible Garmin transducers, including CHIRP, DownVu, and optional SideVu through the GCV 10 black box sonar. That flexibility, together with 10 Hz GPS/GLONASS, sonar recording, wireless BlueChart Mobile support, and NMEA 2000 connectivity, makes it a capable hub for mixed navigation and fishing use.

Key Features

• 10-inch SVGA keyed display provides more screen area for split charts, sonar, and navigation data without moving to a touch-only interface.
• Preloaded U.S. Coastal BlueChart g2 and U.S. LakeVu HD mapping support both offshore and inland navigation from one unit.
• 10 Hz internal GPS/GLONASS updates vessel position and heading ten times per second for smoother tracking and precise waypoint marking.
• Supports compatible Garmin CHIRP, DownVu, and SideVu sonar setups, with optional GCV 10 expansion for broader scanning coverage.
• Sonar recording allows returns to be saved and reviewed later, which helps with post-run analysis and repeat fishing locations.
• NMEA 2000 support and two SD card slots make it easier to integrate the display into a more complete Garmin helm system.

Applications

• Boats that split time between inland and coastal waters and need both mapping sets on one display.
• Helm stations where a large keyed screen is preferred for navigation, sonar, and waypoint work.
• Garmin installations that may expand with network sonar modules, autopilot data, or connected Apple iOS chart workflows.
