PROFILES

Profiles are collections of instrument pages that can be customized. Profiles can be made up of instrument pages that display similar data, such as fuel data or engine data.

During the initial setup, you can select one of four preset profiles, or you can create a custom profile. You can select a different profile at any time.

POWERBOAT: By default, this page displays instrument pages that show GPS speed information, position coordinates, bearing to waypoint, distance to the next waypoint, and a GPS trip odometer.

SAILBOAT: By default, this page displays instrument pages that show apparent wind speed, GPS heading, GPS speed, position coordinates, bearing to waypoint, distance to the next waypoint, and a GPS trip odometer.

FISHING: By default, this page displays instrument pages that show GPS speed, water temperature, and depth.

ENGINE/FUEL: By default, this page displays instrument pages that show engine and fuel information. Available engine information includes RPM, trim, temperature, voltage, oil pressure, fuel pressure, boost pressure, and coolant pressure. Fuel information includes fuel flow rate, fuel tank level, estimated total fuel onboard, fuel pressure, fuel economy, and cruising range.

CUSTOM (1,2,3): Empty profiles that allow you to build a new custom profile. Custom profiles do not contain any preset instrument pages.

FAQs

A nmea 2k Airmar dst810 transducer is what I have. What NMEA components, cables, etc. are required for the connection to the GMi-20?****

To get started, you’ll need a Garmin starter kit, p/n GAR-010-11442-00. Although you could only purchase the N2K power cable, T, and terminators, you might as well purchase the beginning kit instead, which comes with those components as well as some extras for potential growth.

Can the Garmin NMEA 2000 camera’s video be viewed on the GMI 20?****

No, it wasn’t made for that.

Is the GMI 10 replaced by this?****

Yes.

What software version runs on this GMI-20? 3.50 as of September 2021.****

Yes, it includes each of those things.

Can it show the current time locally?****

Yes, you should read the online handbook.

Can I use a nmea 2000 drop cable to connect the gmi 20 to my gpsmap 7616xsv and have it display everything on the 7616?****

There is only one connection type: NEMA 2000. All information should be visible on the GPS; you just need to programme the pages.

Can a Garmin be used on a boat?****

Sonar readings of the water below the boat are provided by Garmin transducers, allowing you to observe the bottom structure, fish swimming (or hiding from you), and more.

How is data stored by Garmin?****

After being uploaded to Garmin Connect, some fitness data from devices that broadcast via ANT is backed up using Garmin Express onto the PC. The computer keeps local copies of the activities.

Are Garmin data reliable?****

95% of the time, Garmin® GPS receivers are accurate to within 15 meters (49 feet).

How does Garmin gauge effectiveness?****

The performance condition function evaluates your pace, heart rate, and heart rate variability to create a real-time assessment of your capacity to perform in comparison to your average fitness level when engaging in an activity like running or cycling.

How long till Garmin finishes?****

a data field that displays your anticipated time of completion for common race distances.

How does Garmin gauge one’s level of energy?****

Body Battery is a function that calculates a user’s daily energy reserves by combining heart rate variability, stress, and exercise.

Does Garmin work in saltwater?****

You can, indeed. Simply wash the watch with water afterward. A shower after the beach is usually fine.

Can a Garmin transducer be mounted in Hull?****

Fishermen can venture out on the water with their preferred Garmin gear thanks to our adaptable in-hull transducer mounting solution for kayaks.
