No more volume control

Latest update crashes when I try to use the slider button with my RA-70n. No way to control the volume from the app. And says update failed when I try to update the head unit. Update: after the volume bug was fixed the app went back to being great for what I use it for, which is being able to control the volume and inputs from the dock or other rafted boats. Still can’t get the remote update to work, but not a huge issue for me.

Jsch19Version: 2.0.1
Sit Back and Control

Great to be able to sit back and have all the controls at your finger tips. After playing some cool tunes up on the flybridge with heavy bass go sit back on the salon couch and change the speakers to the salon and up the treble, change the input from Bluetooth iPhone to Aux TV to watch some football. Then, break out the wine after the game and switch over to be a easy listening radio station and turn down the volume. Easy listening with an easy app . Thanks Fusion for a great app that never lets me down!!! Have fun without having to get up every time you want to make a change.

IGN 7.8/10Version: 2.7.1
Fantastic Stereo and App

I was apprehensive after reading some of the app reviews for this radio. I was transitioning from a 14 yr old stereo in my boat with two hardwired remotes that would no longer function, this seemed like an ideal solution. I’ve used the app a handful of times, both with a lightening cable and Bluetooth to control the radio. The sound is crisp, if you go into the volume control you can adjust each zone separately. However, off the main control screen, I can adjust the total volume with a simple tap, not a slide. Song changing, and changing sources is effortless. I can even tune the stereo settings from the app. Couldn’t be happier.

Jeter786Version: 2.3
A must have!!

This app is amazing when on the boat, I can select which deivice I want paired to the boat, I can also tune the sound and adjust the tower separate from the interior and change the name of all the setting. There is also an option for preset volume levels. This is useful to have one for when your surfing and then when they fall you click the other setting and it turns the volume down quickly. Highly recommend this app!

R̶i̶l̶e̶y̶ D̶r̶y̶e̶r̶Version: 2.7.2
Works great, I’d like to see expanded features

The app works great, better over wifi than Bluetooth. I setup a travel wifi router in the boat and connected a remote to the hidden head unit via Ethernet. As far as the app, more volume presets would be great. It has two and I could really use at least 4. How about tone presets as well changing situations like being at the sandbar vs wakeboarding. All in all though the app is great.

Here’s my view

The app is great on the face…control over the important functions remotely which is a must this day in age…..that said two issues I have is not being able to install updates from the app direct from the phone or tablet, Fusion-Link need to solve this asap. And I would like to be able to change and personalize the profile picture on the unit!!! Give me those and I’ll give you the fifth star!!!!

Capt. Alex 1Version: 2.7.2
Simple app but it works

The app is simple yet effective. I like that I can adjust the different volume zones without having to go through the head unit, leaving more time off the boat and on the sandbar. Couple suggestions for the developers: 1. Allow users to pair systems (boats) and sync music through the app. 2. Create the Apple Watch application! Would be great for when we’re fishing, cleaning or off the boat.

Brass StonesVersion: 2.0.1
Works good

I like the app and all of the functions. Being able to adjust equalizer is nice. The only thing I would like to see change is being able to adjust volume of the system with volume up/down controls on my device and not have to go into the app to change volume.

RDeeJVersion: 5.0
Thanks for the power button!

I had previously requested that this feature get added — allow the user to turn OFF the power via the app. (Powering ON was already there). Glad to see that you’re listening to your customers! Thanks!

Keith-BTVersion: 2.8
App is a game changer

I did not realize how great my Fusion audio system is until I downloaded this app. It unlocked access to the radio’s full potential. Also the app is much easier to control audio and zones where ever we are on the boat.

X3brianVersion: 11.0
Very user friendly

This app is extremely user friendly. Love all the options for adjusting audio levels. The app can control the entire head unit which is great when you’re away from the head unit.

ZclitmanVersion: 5.0
Great job!

I really love this app and it’s interfaces! Before the app, I always had to get up to adjust the volume. A fellow boater hooked me up with the app and my whole attitude changed to one big positive experience! I can do more with the app than I knew how to do with the head unit.

S/V FBGVersion: 2.7.2
So easy to use

I use this system on my boat and the app reaches everywhere on the boat. Actually more convenient to use than the Fusion blue tooth remote on my dash. I’ve recommended this app to my dock neighbors that have Fusion systems and they love it. The art on the display looks great too.

NvgjfchoyfVersion: 2.7.2
Great remote for Fusion gear

It’s a great app, and I use it frequently. It includes all the functionality I need, with an intuitive interface. It’s an excellent remote control. I’m using it right now... :-) Earlier versions of the app had stability issues, but that appears to be fixed with this release.

DelicutKaffeeVersion: 1.1.3
Controlling Fusion stereos over Wi-Fi using the Fusion-Link App

Keeps getting better with time. Performing software updates on Fusion stereos has never been easier. Fusion Apollo SRX400, WB670, RA670, & RA770 are the ONLY marine stereos that have Apple AirPlay2 built in. Streaming music over Wi-Fi using Apple AirPlay2 is the greatest feature ever.

Jack_LeggettVersion: 2.7.2
Fusion mobile app

Been using the app for about 2 years now. The app had a few bugs which have been addressed. Your tech support has been great as well. Keep up the improvements. Great sound on the water is imperative.😀

Jfarley55Version: 2.7.2
Fusion WB675 hideaway

This app works great on my WB-675. I used my iPhone 15 with a usb-c to USB for my updates and it controls everything really well. I also installed the ERX400 wired remote so I don’t have to use the app but it has worked great every time I’ve needed it.

B_radferdVersion: 9.0
Quality App

The Fusion app is easy to use and very robust. Haven't had any issues at all. Updating the stereo software is kind of kinky but it works. It takes a long time and doesn't update progress much.

Pathfinder2400Version: 2.8.1
Full radio control from my cozy seat

Love that we can control all functions of the unit from my phone. Never have to get up and walk over to the radio control, wether it’s Bluetooth or local stations.

Srproin2Version: 2.8.1
Great option for blackbox audio

Less is more on my small center console boat so I went with the Fusion BB100 Black Box stereo and its perfect it’s hidden, enough power for 4 speakers and I can control it with my Simrad or the Fusion Audio app! 👍🏼

Echavez1Version: 11.0
Everything you could ask for

Wouldn't change a thing. Works perfectly. Only thing to ask for is a Apple watch companian app.

RoyCMartinVersion: 2.8.2
Great Marine System

Nothing but good to say regarding the Fusion Stereo receiver for our boat! Very reliable, Bluetooth options are great and it does get wet and continues to work properly! No hiccups! Very satisfied and would highly recommend.

Fusion BoatVersion: 2.8.2
An awesome addition to an awesome radio!

We’ve been using our Fusion radio on our Tug for 5 years now. The Fusion-Link app is a perfect companion to the radio and it is one of the few apps I would not be without!

3jebrhfbhehhdVersion: 2.7.2
Fusion Link

Easy to use. Makes the Fusion radio more enjoyable by being able to control from anywhere on the boat.

Boat StuffVersion: 2.7.2
Very Functional

I can control most everything on the stereo with the App. Haven’t seen a way to power on and off though.

HyrieidiVersion: 2.7.2
Best marine stereo

Great stereo. 4 Separate zone control produced best sound on the boat. Previous system split a single output. Sound was mediocre. Now I can turn the bow down while surfers can jam.

Mpr sailVersion: 9.0
Works Great

Does everything it’s supposed to. Separate controls for different zones. Seperate sub woofer adjustments along with all other basic functions

Joejoe652Version: 5.0
Nice app

All of the reviews are old. Works well with boat and I imagine how it could work well with anything else. Trust recent reviews. Easy to control sound in zones, settings, info, everything. Great app!

MikeyK14Version: 2.3
Love the fusion Apollo system!

Top notch marine audio for the salt water environment. Tech support team is top notch. I just installed a new fusion Apollo head unit, 2400 watt amp, 3 sets of signature series speakers and their sub and my boat sounds incredible.

Chips05Version: 2.8.2
Fusion app

If you enjoy easy access to your electronics and you a Fusion setup, you’ll surely enjoy this app. Great for fine tuning if you have different audio zones.

Marten VVersion: 2.7.2
Farming Fusion App

This App is a very big improvement from the previous APP. Easy to use. easy to connect to other Fusions systems instead of pairing

LaidBack68053Version: 4.0

Nice Display. Intuitive interface.

Well build, easy to use. Makes using the stereo in the boat more accessible and allows easy changes to settings that have multiple pathways within the stereo interface.

Griffin swagVersion: 2.7.2
Nice!

So far no beefs. Easy to use. Responsive. No connection issues so far. I like being able to control my iTunes music functions directly from the app. Also being able to adjust the different zone volumes is excellent.

Part of RV luxe experience

First exposure to Fusion was an easy startup experience. Accessing my music with quality sound via Fusion, great!

PapillomatomaVersion: 2.7.2
Great app, best “remote control”

Very convenient, can set volume for each zone from anywhere on the boat.

Cdp000Version: 2.7.1
Solid and intuitive

AirPlay beats Bluetooth for ensuring video and sound are synced.

TilJVersion: 2.7.1
We know, Garmin owned, but make it iWatch compatible!

I am a Garmin and Fusion fun for at least 10 years, although got into iWatch, as many of us. It might be mostly a tactical choice to not have iWatch integration , due Garmin smart watches direct competition, but might point is still is a place for each product in the market. So please integrate the Fusion with iWatch. I use Fusion on my cruiser and dinghy, great products and awesome integration with the plotter and other toys on the boat. The software works as expected, updates sometimes are tricky to install.

SnakeZoneVersion: 2.5.1
Fusion stereo

Best marine head units in the business.

BartmontanaVersion: 2.7
A pleasant surprise

I’m always a skeptic about such apps but one works really well. Easy to set up and use.

ChimoiiVersion: 2.3
Works great, no issues.

I would like a remote for the home that works this well. Hard on the iPhone battery, but that's because I was using it for 5 hours straight, and showing it to my friends. iPad version looks better, and the iPad as a much better battery life for something like this. Lots of people asked if it would stream music to the Fusion deck...and no, it does not. I'm sure as time goes on, I'll find things I wish they had done to it, but right now, I'm very happy with it.

Fusion Audio Negative Reviews and Ratings

Day 3 app crashed & required an uninstall/reinstall

This app crashed and required an uninstall & re-install after 3 days of using. At the moment it just flashes back and forth between the WiFi screen as a blank screen, which is not very useful. It’s also exceedingly slow to respond and astonishingly difficult to control the volume. Let’s say your music is too loud in zone 3 and you want to turn it down, expect about 15-18 seconds to: open app, select the head unit, select the volume, select zone 3, then frustratingly try to slide the volume down (usually takes about 3 swipes), and finally about 3 seconds before the volume actually goes down. And this is on an iPhone X. Overall not very satisfied.

VinnyMatVersion: 2.1
Volume control is terrible

I loved the original version of the app where the volume control was right on the main screen with the rest of the quick access controls. Now you have to leave the main screen and go into an adjustment section just to control the volume and it’s not a button it’s a slider. The slider has terrible response and it’s a pain to use when cruising down the lake. Please put the simple volume control back on the main screen. This alone makes me not want to use the app. I’ve had friends enjoy my system using the old app and decide to buy a fusion head unit. Now it’s an entirely different experience for the worse.

DuvillaVersion: 2.0.1
My Experience: The Stereo’s Fine, But the App Is Infuriating

I’ve got a Fusion stereo that works like any old-school car stereo from the 80s. The real disaster is the Fusion app: it’s basically useless. It constantly says “no stereo found” even when the stereo is playing music just fine. After hours of trying to pair and re-pair, plus a call to support, I learned I’d have to physically remove the stereo from its mount just to update it. That’s not practical at all on a boat. In short: the app is a nightmare, and I wouldn’t buy this again. Just my experience, but save yourself the headache.

Dan__M_Brown57Version: 9.0
Still no Apple Watch support

It’s been over 2 years since I see people have been requesting an Apple Watch App and still nothing. As others have said, having a remote control on your wrist would be a huge benefit to controlling the unit while around the boat or in the water without having to carry your phone.

VariggingVersion: 2.8.2
Sirius-ly missing Sirius functions

*update* what happened to the ability to tune Sirius Radio from the app. And now missing Sirius Favorites. Now only way change Sirius channel is to walk 30’ use the head-unit to adjust, and walk back because the new app simply does not offer selection of favorites or category tuning. Thanks from trying, but the UX is now a 1/10 because the UI simply fails. App is unresponsive (iPhone X). Update delivers ERROR. Controls simply are not intuitive. Easier to walk to other end of vessel to manually adjust volume. This update / release is a failure.

IslandDogPNWVersion: 2.0.1
Another App That Never Updates

Shame on you Fusion for not updating this app. No integration with Apple Watch? Are you kidding? Get up with the times. We want to be able to control our systems from our watch. The Bluetooth should automatically reconnect to the same device it was last connected to when it returns to the Fusion system. Why should I have to manually reconnect my iPhone to Fusion every time I return to it? WTH?!

RunsWithBonerVersion: 2.7
Needs Apple Watch Support!

It’s a shame that this doesn’t have Apple Watch support by now. The app works well, but no Apple Watch support is a problem particularly when streaming and connected over WiFi. When connected over WiFi, you can’t raise or lower volume using the Apple Watch like you can over Bluetooth.

Jbello27Version: 4.0
Fusion-Link Not Connecting

Would sure like this app to work but I have to uninstall reinstall it every week just so it will connect to my UD-755. Very frustrating. Tech support was helpful and walked me through things to try but ultimately it required the disconnecting of my phone from the stereo and doing uninstall/reinstall to get it to connect. Shame since the app sees the unit but just can’t connect. Hopefully Fusion puts some effort on this and makes it functional.

Stash007Version: 2.3
Clumsy

Great idea but needs to be cleaned up and make it a little snappier (iphone8 so not a phone problem). Also, PLEASE add apple watch support. This would be huge. I have 2 nrx remotes and also linked to my garmin plotter but watch support would be awesome when at the sandbar or anchored and relaxing on the inflatables. Workaround is to connect iPhone via Bluetooth to md-650 and use Apple Watch native music controls to skip songs and adjust volume but that means no independent zone control :(

S88865Version: 1.1.3
Cheesy

New app logo is pretty cheesy and doesn’t represent the quality of brand we were sold to install in 1/4-million dollar boats, old logo was fine. Among other issues with app randomly not pairing to stereos after a few days of non usage and having to play guess what will fix it today. When its working it’s awesome.

NautiqueSurferVersion: 4.0
Not a fan of the generic app icon

The former app icon was useful. The new, generic one is meaningless and more difficult to track (or direct someone else without knowledge of the audio system) down while boating. At least give us the option to set it to the old one.

SthormstrikeVersion: 4.0
From great to crap

Worked perfectly when I got the app months ago - finally went offshore and using satellite radio and went to the app to change station - didn’t work. Called fusion and they said it’s a known bug…..now have to control the radio from inside the cabin to adjust the station. Only happens when using XM radio. Horrible.

DaveyBoy181Version: 2.8.1
Update resets app

The latest update resets the settings in the app, including disconnecting the Bluetooth from your phone. You basically have to set it up like it’s from the factory after downloading the latest update, both on your phone and boat

Mike Mac 1031Version: 2.8.2
It works

It works as described. The range with my RA70 and iPhone 13 is great. It would be nice to control the volume from the phones volume buttons on the side of the phone without having to unlock the phone and open the app.

MD DomVersion: 4.0
Inconsistent

When the app connects, it's decent. However it often shows it cannot find my stereo even when I am playing music from my phone through the Fusion stereo. I just can't control anything with the app. This happens so frequently I don't even try to use it.

K_AutomatonVersion: 4.0
Can’t adjust tone setting

Every time I adjust the tone settings (bass, middle, treble) the change only stays for the current song and by the next song the tone setting are back to the original location. Please help this is so frustrating.

NachohawaiiVersion: 2.3
Volume Controls Need Work

I like the looks but there are too many steps to get to the volume control. I miss being able to adjust the volume with the volume controls of my phone. When you open the app if the music is playing you should be able to adjust volume immediately.

FangottiVersion: 2.0.1
Volume control erratic

App use to work ok now volume changes randomly without any input - seems to happen while I’m using other apps like iMessage or What’s app. Also app settings are inconsistent between zones - some can be disabled others can’t. Poor UI and flaky integration with iOS.

Pablo91011Version: 3.0
Bluetooth does not always connect

When the phone does connect, it plays and acts like a Bluetooth speaker. But the app cannot see the Fusion Radio nor control it. Just searches.

Duma76Version: 2.3
This app is a struggle!

Unfortunately, this app is very unreliable and inconsistent in its ability to connect using Bluetooth. Initially, BT connections were slow to connect but did connect after 10 or 15 minutes, in spite of my iPhone being within 1 metre of my UD-750. I also have a Coast Marine WIFI on the boat which I use as a LAN to connect my laptop, Raymarine instruments, Vesper Marine AIS and Raspberry Pi 3+ computer via WIFI. However, I have not been successful in connecting my Fusion UD-750 to this app though my LAN. Fusion is a great marine stereo, however, I’m concerned that their recent sale to Garmin may be the reason that this app is no longer reliable. 😕
