For trusted Alpine sound quality and the convenience of built-in Bluetooth Plus wireless technology, the UTE-72BT DIGITAL MEDIA RECEIVER offers just what you need. Play your iPod® or iPhone® via USB (cable sold separately) and control music playback and search functions right from the Head Unit. Alternatively you can also switch to Direct Control Mode and control playback from the iPod® and iPhone® directly. App Direct mode allows you to enjoy the sound of any iPhone app through your car speakers while you charge your phone – very handy for internet radio or navigation apps. Use the voice control key to activate Siri on your iPhone 4S / iPhone 5 to control the music playback and place calls. This works also for Android phones with voice control function. Sound quality is greatly enhanced by Alpine’s unique MediaXpander technology, especially for compressed media like MP3. The convenient USB port and 3.5mm auxiliary input on the front of the unit allow you to easily hook up USB mass storage devices or an MP3 player. This unit is not equipped with a CD optical drive.
