$1,935.00
Garmin GMM 150 Multi-Touch Marine Monitor is a 15-inch glass helm display for Garmin GPSMAP 8500 systems. It offers a slim XGA touchscreen, SmartMode support, and broad system integration for navigation, gauges, sonar, video, and multimedia display.
Overview Garmin GMM 150 Multi-Touch Marine Monitor
Garmin GMM 150 Multi-Touch Marine Monitor is a 15-inch display designed for Garmin black box helm systems where space is limited but full touch control is still required. Its slim construction makes it easier to integrate into custom helm layouts while keeping the processing hardware mounted remotely.
The anti-glare XGA touchscreen supports familiar touch gestures and works with SmartMode to keep multiple helm displays coordinated. Because it is part of the wider Garmin glass helm ecosystem, the monitor can be used for charting, sonar, engine data, media and onboard camera views from a single screen.
Key Features
- Compact 15-inch display: The XGA touchscreen provides a useful balance between screen area and helm space efficiency.
- Ultra-thin design: A shallow monitor profile helps support cleaner flush-mount installations and custom helm layouts.
- Touchscreen workflow: Gesture control makes zooming and screen interaction more direct when working with chart and system pages.
- SmartMode presets: Custom preset layouts can be switched across multiple displays together for faster helm changes.
- Readable finish: Anti-glare coating and auto-dimming support better visibility in bright sun and lower-light navigation.
- System-wide display role: The monitor is designed to show navigation, sonar, engine, gauge and multimedia information from the Garmin network.
Applications
- Compact glass helm installations built around a GPSMAP 8500 processor.
- Boats that want a dedicated 15-inch touch display for navigation and vessel data.
- Helm layouts where a separate monitor is preferred over a bulkier all-in-one display.

Frequently Asked Questions About Garmin GMM 150 Multi-Touch Marine Monitor
How is Garmin GMM 150 Multi-Touch Marine Monitor intended to be used at the helm?
Garmin GMM 150 Multi-Touch Marine Monitor is built as a dedicated touchscreen monitor for a GPSMAP 8500 black box system, giving operators a separate interface for radar, sonar, charting, and other onboard functions. It suits helm layouts where processing hardware is mounted remotely and the visible display remains clean.
How does this touch display improve everyday control?
This touch monitor supports direct touch interaction, so operators can work with helm functions through familiar gesture-style control rather than relying only on external keys. On systems designed around a separate processor and display, that makes the interface faster and more intuitive to use.
How does this marine display support readability at the helm?
This unit uses an anti-glare screen, auto-dimming, and 1024 x 768 to keep information clearer through bright daylight, reflections, and shifting ambient light. That helps when radar, charting, or system data must remain readable during long watch periods or busy helm operation.
What kind of helm layout is this unit best suited to?
This marine display is intended to complement a GPSMAP 8500 glass helm installation, where multiple screens and black box processing are coordinated across the helm. SmartMode support also helps compatible displays change layout together for navigation, sonar, gauges, media, and monitoring.
