The StreetDeck bluetooth dongle is in beta testing (and has been so for quite some time) and is not currently available. So using using a jawbone with SD would not be possible as of now. Note most people want to use bluetooth for hands free in which conversation audio is heard through car speakers in conjunction with an external mic.
Also keep in mind currenlty the audio quality (how well callers hear your voice)for bluetooh phone via CarPC is nowhere near what you will get using your jawbone without CarPC or an after market kit such as the ones available from Parrot.
You may also want to strongly reconsider using StreetDeck as a front-end as there has been an issue with support for the product for the past few months as seen in the link below.
