I also have problems connecting to my car's Parrot 3200LS, I have to disable phonebook syncronization, otherwise the HF keeps trying to sync and mutes the audio every 10 seconds or so. Sometimes the HF tries to connect automatically and the BT icon on my N9 keeps flashing blue, only disconnecting and reconnecting from the HF helps. My gf's N8 works perfectly, I can even browse the phonebook. I think it has something to do with the N9-s implementation of BT HF profile.. my other thought was that maybe the HF cant sync the contacts because they are synced with my company's Exchange server. anyway it's quite annoying.
