BMW currently offers buyers the the ability to stream music (wired) and use a mobile phone wirelessly. You can use your Apple iPod (or many other music player) through the optional USB audio interface – and for wireless hands-free mobile phone calls use Bluetooth (included with BMW Assist or the premium package) both can be easily controlled via the car ‘s infotainment system (iDrive or the radio).
The real news is that BMW is currently developing an in-car Bluetooth-based playback solution for music files. It will offer stereo quality music streamed from a device (must be compatible) wirelessly to the cars infotainment system. The files would remain on the device and not need to be transfer to the car system in any manner.
This capability will use the Bluetooth A2DP (Advanced Audio Distribution Profile) and AVRCP (Audio/Video Remote Control Profile) standards. A2DP takes care of the actual audio streaming, while AVRCP allows the audio output to be controlled through the vehicle’s infotainment system. Devices currently available allow audio streaming but only with simple remote control functions such as start, stop, pause and skip. Bluetooth audio streaming will only be able to offer the features you currently expect in a BMW (such as track selection) when the next version of AVRCP arrives. The development of this standard is ongoing and promises these additional functions.
Will the sound quality match that of “wired ” devices is yet to be seen, but we are fairly sure BMW will make sure it does. It appears the next generation IPods/Iphone may offer this technology as BMW has shown that they and Apple often collaborate on these sort of things. Lots of new technology will be available in the not so distant future. Source: BMWAG
