Overview Garmin GMM 170 Multi-Touch Marine Monitor
Garmin GMM 170 Multi-Touch Marine Monitor is a 17-inch helm display built for Garmin black box navigation systems. It is designed to give glass helm installations a clean appearance while keeping the processing hardware mounted separately from the visible display.
The multi-touch glass surface supports familiar gesture control, and the anti-glare SXGA panel is backed by LED backlighting with auto-dimming for day and night readability. SmartMode support and integration with compatible sonar, autopilot, engine and media functions make it a flexible monitor for larger helm layouts.
Key Features
- 17-inch touch display: A large multi-touch viewing area helps present charting, video and system data with clear separation at the helm.
- Ultra-thin installation profile: The slim design supports cleaner flush-mount layouts and gives more freedom in custom helm design.
- Readable in changing light: Anti-glare coating, LED backlighting and auto-dimming support visibility across bright daylight and low-light operation.
- SmartMode support: Custom helm modes allow multiple displays to change layout together instead of being adjusted one by one.
- Integrated glass helm role: The monitor is intended for use with GPSMAP 8500 processor systems and supports navigation, sonar, gauges and media display.
- Multiple video interfaces: The available video inputs help the display serve both navigation and onboard monitoring duties.
Applications
- Flush-mounted glass helm systems built around a Garmin black box processor.
- Larger helm layouts that need a dedicated 17-inch touch display for charting and system data.
- Boats that use video feeds, gauges and marine network data on a single display surface.

Frequently Asked Questions About Garmin GMM 170 Multi-Touch Marine Monitor
Where does Garmin GMM 170 Multi-Touch Marine Monitor fit in an integrated bridge setup?
Garmin GMM 170 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.
What are the advantages of the touchscreen interface?
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.
Why is this touchscreen suitable for marine viewing conditions?
This unit uses an anti-glare screen, LED backlighting, and auto-dimming 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.
