Depending on the phone and OS version it's running the Bluetooth capabilities are a mixed bag of protocols and profiles, and implementation of them with the individual installed applications on the phone also varies. ( http://developer.bluetooth.org/Knowl.../Profiles.aspx
) Add the MyGig uconnect layer and we have what we're living with today.
I've read of users having good success with the iPhone 4s and Siri getting SMS text messages to be read aloud over bluetooth, but not composing new messages or responses.
My best guess is that an application, event or process evokes one of the supported protocols or profiles, such as the the Bluetooth A2DP profile with the MyGig, and you get the mobile device's audio stream on the MyGig. Anything that you might hear via the mobile device's speaker you'll hear over Bluetooth, even if that application or event doesn't evoke that particular protocol or profile, kind of like a hitchhiker. That might be why users report getting intermittent audio from a variety of different applications and events.
One way to skin this cat would be to create an app on the various platforms (iOS, Android) that interfaces with the MyGig/uconnect at the application layer. This app could establish the supported connection, say A2DP, and maintain it, and then everything that you'd hear on your device you'd hear on the MyGig. A little development would result in a solid app that could employ several profiles and protocols that would result in tight integration between phones/media player and the MyGig. I would expect the manufacturer to develop the app, but I also expected the system to work as marketed, which it doesn't... not a single device supports the SMS text feature on the 730N, not one.

I guess we can just wait and hope that Chrysler will make good on the marketing promise, but I'm not confident that will happen. Hell, even as updates are released in manufacturing, there is no acknowledgement that there is a problem and they are working on it, nor are those incremental update made available to owners. If it weren't for leaked versions from the OEM, HB we would have any hope.
This isn't my first experience with factory installed nav/media systems, and unfortunately none of them, Acura, Ford, Subaru and Jeep have been satisfactory.
