The New iSimple Dual Link (iSMZ531 ver. .816b) adapter gives users the option to connect up to two audio devices for 100% digital-quality sound on their factory radios from almost any type of portable audio device. In the past this was possible with an FM Modulator but the sound quality were inferior and interference levels were unacceptable. The iSMZ531 Audio input adapter allows you to connect up to two audio devices to the factory radio in select 2009-12 Mazda listed in the "Select Compatible Vehicle " drop-down menu below. The iSMZ531 connects to the Satellite Radio Port on the factory radio to deliver 100% CD quality sound from your portable audio devices (MP3, DVD Audio, Satellite radio kits, computer, Game System, iPod, Zune etc).
