Detailed description
Garmin GPSMAP 923: A connected helm
The Garmin GPSMAP 923 brings navigation, boat information and compatible equipment functions into one installation. It is designed for a helm that can grow with the boat's requirements, from checking position and preparing a passage to adding radar, instruments or fishing information. Combination views help relate mapping to available data and let you choose the information most useful for cruising, manoeuvring or searching for a fishing mark.
Display and controls
This version has a 9-inch display. Touchscreen. The resolution and dimensions in the table apply to this model, allowing console space to be checked before installation. Views can be organised to show mapping alongside information from connected equipment. Field sizes and data arrangements allow the interface to be adapted to the helm while retaining the navigation reference.
Navigation and mapping
Navigation features allow waypoints to be saved, routes to be planned and tracks to be recorded. This part number is supplied with a worldwide basemap for general reference; detailed local navigation charts are not included. Optional Garmin Navionics+ and Garmin Navionics Vision+ charts are supported. Coverage, advanced features and updates depend on the selected chart and subscription. Auto Guidance+, where supported with suitable charts, is a planning aid: always check the route against actual conditions, depth and the boat’s limitations.
Garmin SailAssist offers sailing information such as laylines, start-line assistance and polar tables. Wind data and other values depend on compatible sensors and correct configuration. These tools help interpret manoeuvres and adjust sailing performance while the skipper remains in control and checks the surroundings.
Sonar and expansion
This version has no built-in fishing sonar module. It can display sonar information when connected to a compatible Garmin source or module through the appropriate network. Panoptix and LiveScope systems, sonar modules and their transducers are sold separately. This configuration suits navigation-focused installations or boats where the fishing system is selected independently. Check the exact network, software and connector compatibility before adding equipment. An instrument depth sensor is not a substitute for imaging sonar.
Networks, instruments and ActiveCaptain
NMEA 2000 and NMEA 0183 connections integrate compatible instruments and equipment for onboard information. Garmin Marine Network allows information to be shared with supported devices such as other plotters, radar, cameras and sonar sources. Built-in Wi-Fi links ActiveCaptain to a compatible smartphone for software updates and mapping functions. AIS, VHF, autopilot, audio and engine information require the relevant equipment and connections. Display compatibility does not mean these accessories are included.
Version and equipment
The exact part number stated on this page is supplied with the items listed in the box contents. Fishing transducers, radar and additional sensors are not included unless expressly named as part of the bundle. Charts shown in demonstration photographs do not determine the mapping supplied.
