Garmin GNX 21 Marine Instrument Display

The easy-to-read GNX 21 marine instrument has an inverted display with white or colour digits on a black background that clearly shows depth, speed, wind and 50-plus marine and boat parameters. Its glass-bonded display with anti-glare lens coating provides excellent daytime and nighttime readability with high-contrast digits scalable up to 36 mm. Its low power consumption — (25 mA) with 350 mW (no backlight)/400 mW (mid-level backlight) — is perfect for use on sailboats, and provides a valuable instrument for cruising and fishing. Fully customisable user profiles display wind, depth and speed data. Plus, the GNX 20 includes an auto-scroll feature that rotates through data screens for hands-free operation. It can be installed with the included low profile flush mount or an optional flat mount for the ultimate glass helm solution and custom look for your boat.


Features


• Large, easy-to-read white or colour digits on a black background for high visibility in low-light or darkness; choose from 7 customisable backlight colours • Auto Scroll -Set your display to automatically cycle between pages at a speed you set for convenient, hands-free operation.


• Customisable User Profiles - Fully customisable user profiles allow you to choose from 5 available display configurations for sailboat or powerboat user-profiles: single, dual and triple function, plus gauge and graph mode to display wind, depth and speed data, or customise the pages to display the marine and boat data that is most important to you.

Returns

Standard Returns

If you are not entirely happy with your purchase, we will exchange or refund your goods in full, provided that the items are returned within 14 days of receipt.*

Please check the condition of goods on arrival - we are unable to accept goods damaged during shipping after 14 days.

Returned goods must be packaged securely, with all original packaging undamaged and in a saleable condition i.e. shoe boxes must be in the same condition as when received.

Goods must be unused and security seals intact.*

If you would like to return goods because they were ordered incorrectly or if clothing does not fit, return postage will be at your expense. If you would like us to replace the goods with another size or colour, we will charge carriage on the replacement.

Please be aware that some navigational and safety products may be dated, and as such a full refund may in some cases not be possible. If you are purchasing dated navigational charts we suggest you contact us for more information.

If you receive your goods and believe them to be faulty, please contact us straight away with a brief description of the problem. If we require you to return the product for a replacement, we will send you a pre-paid Royal Mail label for delivery back to us. Unfortuantely we cannot send the courier back to collect the items.

Returning goods to Force 4 is easy!

  1. Please contact us by ringing 0345 1300 710 or email on returns@force4.co.uk.

We are unable to process the return of faulty goods that we're not expecting.
  2. We'll then give you a returns number. This returns number will need to be clearly marked on the outside of your parcel so it can be identified on arrival. Please note, failure to mark a returns reference number on the outside of your parcel may result in a delay in processing your return.
  3. Don't forget your proof of postage, just in case!
  4. Once we receive the item we'll be able to proceed with a refund or an exchange.
