## What is Link?

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.

### 2/5 — Danger iOS 26.5

*2026-05-27*

Ne fonctionne plus avec iOS 26.5 …

### 1/5 — Sonar log uploads no longer work

*2025-06-23*

I thought I found a way to upload sonar logs to genesis, but genesis switch to a single sign on with Simrad last year and this app was not updated. It won’t allow us to log in to upload genesis maps!

### 1/5 — Zeus sr support

*2025-03-24*

Is it compatible with Zeus sr? Why is Zeus sr not listed?

### 2/5 — Non funziona

*2025-01-26, version 4.3.6*

Do due stelle perché non riesco a capire perché non riesco a collegare il mio iPhone 15 se non disattivando i dati cellulare. avendo attiva solo il Wi-Fi si connette e va tutto bene, non appena riattivo la rete cellulare si disconnette. Non posso disconnettere la rete per far funzionare l’app con lo strumento HDs gen 3!!!

### 1/5 — Lack of ability to pair a B&G Zeus S to IPad

*2024-06-16*

Unfortunately, we have just installed a B&G Zeus S chart plotter and, whilst the iPad connects to the hotspot there is no functionality with mirroring functions.

### 1/5 — Better to use raymarine

*2024-05-16*

I change from raymarine to Simrad/Navico. With raymarine you where able to handle your autopilot with the app for free.
Here now we speak about a safety reason not to steer your autopilot by phone.
As you by all the extra parts, suddenly there is no risk anymore to steer with a Simrad Remote Control.
Hey guys i allready spend a lot of money for all the components of your system. So service by app to steer by applewatch - this is too much for you?

### 1/5 — Application française

*2023-09-25*

Comment mettre votre application en Français.. on ne comprend rien du tout..

### 1/5 — Never works

*2023-05-08*

I’ve been able to pair the app to my Simrad GO9 a couple of times and everything worked pretty well. However, I’ve never been able to save any trip info, waypoints, etc. to the app for viewing at home. In fact, at home I can’t even get it (the app) to bring up ANY information. Lately, every time I try to connect to my on-board Simrad the app says my password is incorrect - IT’S NOT! Can’t even connect. Will delete this app and am searching for a better one.

### 2/5 — Sort of works

*2022-11-16, version 4.3.6*

Installed this on a new iPad to mirror my HDS Live unit in the back of the boat and the screen mirroring seems to be lower resolution, the transfer button won’t upload my recorded data to C-MAP Genesis, keeps saying “Can’t Login” “Check username and password” yet I can login on the website just fine.  Been like this end of summer and now fall. A bit frustrating.

### 3/5 — Apple Watch Option missing

*2022-10-25*

The App works well on iPad and iPhone. In sunny weather you have to take care not overhead the iPad. This is not a problem of the App itself. We miss a possibility to control the autopilot via the Apple Watch. Could you add this feature in the next update? This would be really nice feature.
