There are quite a few things that make the Fusion MS-AV700i marine stereo unique and worth a look. At first glance you might get sticker shock at the MSRP of $669.99, but high end buyers will want to explore the remarkable features of this unit.
One of the most remarkable is the NMEA compatibility which allows the unit to be integrated into an NMEA network on your vessel. That means connectivity with chart plotters and other NMEA devices. The waterproof wired remote (sold separately) is connected by NMEA cables and it even comes with cable and a T connector for adding it to your network.
Another high end feature is the ability to connect this stereo to a local area computer network via the rear ethernet port. This opens up a lot of possibilities, including the ability to control the stereo wirelessly via an iPod or iPad using the app download provided by Fusion.

Of course there is also a USB port for connecting virtually any digital device including iPhone 5. Transition to iPhone 5 compatibility has been a difficult one for many marine stereo manufacturers, but Fusion has jumped in with both feet in an effort to keep up with consumer demand.
