Fusion MS-RA770 Apollo Series AM/FM/Bluetooth Touchscreen Marine Stereo

We replaced our UD 750 with this new unit and the sound is fantastic. We had to use the adapter kit which fits perfectly and gives a beautiful appearance when installed. The sound is better then ever and it's nice to be able to control everything through the app now.

I was installing the unit and dropped the unit a short distance and the glass cracked on the front. I was shocked it would break that easily. I also noticed someone else had a similar experience with a cracked screen. Not sure what type of glass is used but likely not gorilla glass or something more durable. A called Fusion and ask if they can repair the glass but i was told me I would need to buy a new one. 700 bucks down the drain. Beware of the fragility of the glass.

The Fusion Apollo is just an outstanding marine head unit. The sound is extraordinarily. Easily to install. It pairs perfectly with the phone. The fusion link app is flawless and controls the sound. I bought a wireless remote that is a must have. Everything Fusion says about the stereo is true.Buy this one. It’s worth it.

I have a setup consisting of 7 zones and 2x MS-RA770. I bought these units primarily for the partybus feature, multi zone control, and ability to integrate and control via onboard network / phone app.I've overall been underwhelmed by the performance of these units given the price point and specs. I bought these units when they were first released and have updated the software continuously to latest version. All issues I mention below have existed since the first release and till latest software revision.The partybus feature is unusable for me, and therefore I could have achieved similar results with a product 1/5 the cost. As such, I am giving a rating of 2 stars. If partybus worked correctly, I would give 4 stars, with 1 star off for the software bugs with bluetooth and app control.Details on my issues with this product:- Phone app control is unreliable. Often, the radio will not show up in the app despite radio being on and phone being connected to onboard wifi. In this case, I need to completely shut down the app, and re-open it, and sometimes also reboot the radio. I have this issue on both my Android phone and Iphone.- Long standing bug where control of the in-built subwoofer crossover does not work correctly. It often resets back to 50hz, and sometimes it takes several reboots before it will allow adjustment. It is not possible to disable the crossover completely (this would be preferred) and adjust on the amplifier.- Partybus introduces an undocumented ~500ms delay in the system. This delay is active on all inputs that have partybus "enabled" (even if you are not actively connecting the second radio to the partybus). This means if you plug a TV into the stereo, the sound is out of sync. Fusion support could not figure this out for me and through trial and error I eventually figured out I had to disable partybus for this specific input.In my particular case, I also often have live DJs onboard and in this case, I can't use partybus to link the radios without a delay, so I had to run an analog audio cable between the radios (a 100ft wire run through multiple conduits, not an easy task). A large reason I bought these radios was to be able to link all the zones digitally, and with minimal delay, so deeply disappointed in the partybus feature. 500ms audio delay is completely unacceptable.- The Bluetooth functionality is horrible. The worst I have every used. It's not intuitive. No one onboard can figure it out without me instructing them on its use. Even then, it doesn't work right half the time and we end up just giving up and using an aux cord.First of all, it needs to be manually put in discover mode to connect a new device. Most modern bluetooth audio devices are automatically discoverable when no device is connected. The discover option is buried at the bottom of the list of existing paired devices and looks at first glance like just another device. If you accidentally click one of the devices instead of the discover button (easy to do with touch screen + boat moving), it locks the radio up for about 45 seconds as it tries to connect to that device.Secondly, about 50% of the time, the radio just simply does not appear when in discover mode. If this happens, the radio must be restarted.Thirdly, about 20% of the time, the first pairing attempt fails in an unintuitive way. The phone will say paired, but the radio will not add the device to its list of paired devices, and audio will not play despite the phone indicating a bluetooth audio connected. In this event, the radio needs to be restarted, and you need to try pairing from scratch until the radio shows the new device in its list of devices.Fourthly, handling of multiple paired devices is unintuitive. I can't explain exactly how the radio handles it but it seems sometimes connecting a device boots the old device, other times trying to connect a new device when an existing connection is in place results in a "cannot connect" error.- Partybus does not work well over wifi. A hardwired ethernet connection is basically a requirement for reliable playback (delay is fixed and remains).Overall, I can't recommend this product for a larger boat with complex multi-zone setup. But, at the same time, there is no competing product with similar specs and better execution. If you have a larger boat, and radios will be installed in an indoor environment, I'd look at high end home audio equipment instead of this.

IT looks good ,but a little complicated to usedWifi,bluetooth range its good,not always new upgrade it's better than the one before.

I like the fact you can setup 4 zones.

cant buy a better marine stereo. easy to use and set up.

Product came with a defective screw that the screen when I was installing the screw. Cracked the touch screen. I followed the instructions to the tee. Pre- drilled holes, even ran the screws in and out with out the stereo installed. See picture of defective screw and broken screen. Highly disappointed. Contacting manufacture to complain. This is the second Fusion Stereo I have bought. Bought a brand new Centurion and immediately replace stereo with Fusion. Have been very happy. Bought this stereo to install in my bar to be able to Party Bus. Was also going to buy one for my kitchen and deck. Not so sure now! Product great just very upset about what happened.
