Android/Aux Integration

Android Direct Connect via USB: The Alpine CDE-170 enables playback of stored music and music apps on select Android devices through its front-panel USB port. There are two types of modes (AOA 2.0 or MTP) to choose from based on your type of Android smartphone and what content you want to listen to.

• AOA 2.0 (Stored Music & Music Apps): The CDE-170 supports Android Open Accessory 2.0 (AOA 2.0), which lets you connect your Android smartphone (OS 4.1-7.1.2) to the CDE-170's front-panel USB port and listen to stored music and music apps from your Android device through the Alpine head unit. You'll be able to control basic playback functions, such as Play/Pause and Previous/Next Track. Other advanced music navigation will still be done from your Android smartphone's touchscreen. In this mode, the head unit will not display song/artist information; only "Android Mode" will show up on display. You'll continue to view song/artist information from the Android device's touchscreen. You'll still be able to access other functions and applications from your Android smartphone's touchscreen, while listening to music through the head unit. If you make a call or answer a call from your smartphone while listening to music in this mode, the music will pause until you are finished with the call and then start back up again.
• MTP (Stored Music + Song/Artist Info): The CDE-170 also supports MTP for playback & control of stored MP3/WMA music files on your Android (OS 4.0+) device through the Alpine receiver's front-panel USB port. In this mode, you get basic playback control (like Play/Pause & Previous/Next Track), plus song/artist information on the receiver's front-panel LCD. During MTP connection, you cannot use your Android smartphone's touchscreen to control music playback and you cannot select music apps from your smartphone for playback. However, you can continue to listen to stored music on your Android smartphone through the head unit while you check your Calendar, Facebook, Texts, etc on your phone.

Auxiliary Input: The unit is equipped with front-panel minijack (3.5mm) auxiliary input, so you input audio from an auxiliary source unit; such as a portable MP3 player. You can adjust the volume level of your connected Aux device from -8dB to +18dB, negating the need to adjust the volume level between sources each time.
