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.

Ratings and Reviews


Really buggy

The old App used to work fine but the GoFree link is really slow and is almost unusable with my Zeus plotter. It works for a while and then slows down and just stops working. I have reset the wifi, tried it on another iPad and installed the new hardware update to the plotter but it still barely works. Please sort this App out!! Don't bother downloading it until it has be fixed.


Remote crashes

Both backup functions work fine, after manually connecting the app to my Vulcan 7. However when I click remote the app just crashes. So useless....

Developer Response

Hi Malc,

We've just released a new version, can you update the app? If you still experience it crashing please let us know.


So needs updating urgently

This app needs updating.

First it's quite buggy and looses connection

Secondly the display gets truncated on iPhone 7 plus. And the features are so reduced it is useless

Come on Navico let's have a decent update.
