The Link app gives you remote control of wirelessly connected Simrad, Lowrance, or B&G multifunction displays from your smartphone or tablet. Link lets you select any wirelessly connected display on board, duplicates the screen in real-time on your mobile device, and puts control of most display functions at your fingertips.

Work with charts, sonar, and radar, control your on-board entertainment system, view data from connected engines and instruments, and much more. With Link, you’re constantly connected to your boat’s key systems from anywhere on board – making it easier to plan trips, fish, sail, handle maintenance, and otherwise make the best of your time on the water.

Link also gives you the ability to wirelessly back up and restore waypoints, routes, tracks, and display settings directly to your mobile device. This makes it easier than ever to protect your valuable boating data against loss or theft, and to keep your backups up-to-date with zero hassle.

The Link app is compatible with Simrad NSS evo3, NSS evo2, NSO evo2, NSS7/8/12*, and GO series displays; Lowrance HDS Carbon, HDS Gen3, HDS Gen2 Touch*, HDS Gen2**, and Elite Ti fishfinder/chartplotters; and B&G Zeus³, Zeus², Zeus Touch*, and Vulcan sailing chartplotters. Displays without built-in wireless connectivity require an additional WIFI-1 module. To enable the Link app, a free software update may be required for your display.

Link works with the Apple iPhone 5s and later devices running iOS 9 or above.

* Mirroring only. ** View only.

What’s New

Version 4.3.6

Fixed the Mirroring and Remote Control experience. Chart-plotters are now mirrored in fullscreen once again.

Added support for Local Network Access permissions. Link will now request access to your local network to communicate with your Marine devices, enabling devices to be automatically discovered and used by the apps features.

Great idea, poor execution.

As mentioned before, this is a really great idea, but poorly implemented. I used it today and it would lock up every time I took a screen capture. Also, there is no auto-rotate feature, so you are stuck in landscape mode, but only in one orientation. Also, when connected to your unit via WiFi, you loose the ability to use cellular data. This means you have to constantly disconnect and reconnect from the unit. Tested on an iPhone XS using both a Lowrance Elite 7Ti and HDS 9 Live. It’s better than taking pictures of the screen, but just barely. If they can work out the bugs, this will be a really useful application.

Works great for me

I’ve been using the Link app on my iPhone to serve as a remote display and control for my Simrad NSS9 Evo 3 unit with FMT tracks for over a year now. The clarity of the satellite image is equal to that showing on the unit, and all the control functions do work. However there is some lag in the screen updates that would prohibit trying to use only the app at a second helm. But for my slow speed use while fishing away from the helm it’s just fine.

As some have noted the WiFi connection to the unit does result in a non working internet connection error on a cell phone, but considering there typically isn’t a cell signal where I’m fishing it’s really not a problem.

Based on the success of my using the app on my iPhone I’m going to start using it on my iPad so I don’t have to zoom in/out as much. Mounting is simply a GoPro adhesive camera mount stuck on the back of an Otterbox case that I put on my GoPro claw mount. EzPz.

Useless for Zeus Touch - part 3 - old GoFree reinstalled

Part 1: Upgraded to 4.3.5. As others report simply doesn’t work correctly.

Do not upgrade! Need to bring back older version. I am very upset by this. Future hardware upgrades on my Swan will not include Navico unless better software management isGuys: this is important stuff that has to work for additional safety. Put an older version up, even the old B&G gofree worked better and then play to your hearts content. “Working on it” is a poor response when a simple revert to an older version will satisfy your users until you get finish beta testing your sexy new product. Very poor software management.

Part 3:
B&G GoFree is back on the app store, at least I could pull it from my purchased list now, when before it linked to Link version 4.3.5. It works fine with my Zeus touch.
Perhaps Navico has taken their first step toward better software management rather than “app” development. If so, thank you. Wish they could communicated with me but at least I have a working system. Note that “Link” is hard to find on the app store. Maybe they should go back to the GoFree name.
A commitment towards legacy support is more important for sailors, but less sexy, than adding unneeded buggy new app stuff for boat show demos with full connectivity. Lets see a move in that direction and i will buy more Navico gear.
Last note that leaving reviews seems to be the only way to get a response, however minimal, from Navico.

Developer Response ,

Thank you for your feedback. We are working on a solution.
We have launched the new app which can be used to sync your MFD, plan your trips and mirror your devices. Many other features to come.
