FeaturesThe iDA-X305 is a mechanical-free device with no moving parts. That means no CD-slot and no tape player. With the exception of the AM/FM radio, the X305 subsists on a completely on a digital diet.
Using the included USB pigtail, listeners can plug in a portable USB drive or MP3 player for complete access to the file structure. Compatible file formats include DRM-free MP3, AAC, and WMA.
In a nice tip of the hat to iPod users, Alpine has included a short, black dock connector cable with the X305, which looks cleaner and keeps us from having to carry our stock white cable back and forth.
New in the X305 is full “Works with iPhone” compatibility, so no longer will you get a nag screen when connecting your iPhone 3G. Additionally, the X305 will also charge your iPhone while you listen, something that the X100 didn’t do.
While the iDA-X305’s feature set is essentially limited to radio and digital audio playback, it is capable of being extended and expanded with Alpine’s line of add-on modules. We already mentioned the KCE-400BT, but the X305 is also compatible with Alpine’s TUA-HD550 HD Radio tuner with iTunes tagging functionality.
