- Technical support from FUSION Electronics
The Verizon network release of the iPhone 4 CDMA version requires a software update to the MS-RA200 to support audio output. The phone is available in the USA only. To obtain the software update which is installed in the MS-RA200 by loading a file onto a flash drive and then updating very simply, contact the Fusion regional office via the contact form link The software version is 2330 and you can check what current software version you have by looking in the settings menu and selecting the About function.
There are 2 power wires and 1 ground wire that needs to be connected for your Fusion Marine stereo to operate correctly.
Both the Red and Yellow wires need to be connected to 12V and the black wire to ground/battery negative.
The yellow power wire is the high current supply wire. This needs to be connected to your battery using a cable suitable for carrying at least 15 amps.
The Red power wire is a switched input. When 12V is connected to this wire the Marine stereo can operate. When disconnected the stereo will shut down and remain off.
The Red wire may also be connected together with the yellow wire if you are supplying power through a switch panel capable of 15A or if a battery isolator is used to disconnect the battery when not in use.
The yellow +12v wire in some Stereo's provides power to the memory of the unit for presets etc this only applies to Fusions MS-CD80 as Fusions 600 and 200 series Stereo's are designed to save all settings when power is removed.
The first thing to check is that the USB device is formatted to FAT 32 and contains MP3 files as that is the only file type supported. The first software version 10.1573 supported USB file name and path lengths to a maximum length of 99 characters. There is an update available for the Operating Software of the MS-RA200 which incorporates an increase in the number of allowed characters. To check the software version you have currently enter the “Settings Menu” then select “About” and the version should be 10.1573.

The first thing to check is that the Volume Limit setting for that zone is not at the minimum setting. Check that the speaker wiring is not the cause by checking the connections at the Head Unit and the speakers. Also ensure that t he wires are not touching any metal part of the vessel and/or touching each other as this could cause the zone to have no audio. If it is an amplified Zone ensure all connections are correct and secure and that the amp level is not set to zero.
A simple way to try and locate onboard sources of interference is to use a portable AM/FM Radio and use the aerial to point at different areas or electronic devices while in AM mode. You will hear the audible interference as you pass the source of interference. You can also eliminate sources by turning things off to see if there is a marked improvement and work your way through your electronic devices to determine what if any are contributing to the issue.
There are a number of things that can cause poor AM/FM reception in a marine environment. One of the most common causes is Antenna cable routing. When installing an AM/FM receiver on your vessel spend a little extra time to investigate the optimal routing of cables including any RCA cables. Ideally they should be run away from any other cable and or electric motors or potential sources of interference. Power cables are the worst source of interference and can be in bundles of cable so you may not realize they are there. AM reception requires a short Antenna cable run for optimum reception which is not that easily achieved on a lot of vessels especially when using mast style aerials.
Check that you have selected the correct Tuner Region in the settings menu as the default setting may be imcorrect for your location.
