Hate to be the bringer of bad news, but there are problems it seems.

The problem seems to be that you can hear the person on the other side, while they can't hear you. There's a bit crude workaround for this in first link (switch to handset sound, then immediately back to car audio sound).
Also, someone with 2010 Nissan Maxima reported the problem of phone crashing when the phonebook starts to sync (Maxima should have the same BT hardware/software as new Infiniti models)
