    Based on the Bluetooth standards, phone communication happens using HFP (Hands Free Profile). A2DP mono/stereo would be used for streaming music and not for phone communication. But still, I don't rule out the possibility that A2DP mono is supported (just that it won't be used for phone communication). I have a strong feeling that the BlueNMe units are not going to support A2DP stereo due to hardware limitations (the Bluetooth controller used in the unit).

    All versions of Windows Automotive / Windows Auto / Windows Embedded Automotive are derived from Windows CE (now called Windows Embedded Compact). Windows CE is the base for building up most of the embedded OSs like Windows Auto, Windows Mobile etc,. Lauberhorn must be a code name used by Microsoft/Fiat for a particular release of Windows Automotive.

    ARMV4I is the architecture for which the OS is built. It is a limitation of Windows CE releases before Windows CE7. Even if the hardware is based on ARMV7 architecture, Windows CE6 and older releases didn't have a build system (compiler, linker etc.,) to generate instructions for architectures beyond ARMv4I (and so every hardware would work with severe limitation of not exploiting the ARMv7 core's full capability). So, we can't be sure about the hardware based on the file name.

    Your observation for HFP is correct. I guess the device doest has A2DP, but OS supports it.

    There is an android app for streaming audio to the Bluetooth mono headsets called BTmono. Search for it on play store.

    But it doesn't work on all phones.

    Cool.. I have downloaded some from Play. Will give them a try from my S2.
    If it gives good quality music, then I can enjoy my drive without getting disturbed by co-passengers asking me to change the audio track. Fiat could have thought about adding separate buttons along with steering controls to skip track and FM stations. May be Fiat is so oblivious with their BluenMe and doesn't look at what technology the current market can offer. I would say BluenMe technology in Indian Fiat cars are outdated (in terms of features and the compactness) when compared to current trends. Pathetic that they didn't find a much better place to fit the BluenMe unit instead of occupying the glove box.

    I don't think you will enjoy music a lot when you stream them in mono. It will be more or less like listening to some old radio stations.

    Yes. It's called BTMono from Google Play. I am able to stream the music as mono.

    well, it may not be that easy or rather impossible. Currently we were able to stream music in the form of "Call audio".
    BluenMe doesn't respond to SDP request with the "Media Audio/A2DP stereo" profile. In order to stream music, the BluenMe unit (the headset) needs to run a specialized software (A2DP stereo stack) which can decompress the high bit rate data streamed by the mobile phone. So, we may need to wait for FIAT's update.
