Simple answer is that it won't work - I used to have a Parrot CK3000 and could not get it to work. Music from the Hero is transmitted using the A2DP Bluetooth profile. The Parrot, being a car phone kit, only uses handfree and headset BT profiles. I guess your Nokia used those ports to transmit music
Even if you get it to work by tweaking the Hero the sound quality would be mono and pretty poor, which is a limitation of the headset/handsfree profiles.
The newer Parrots support A2DP profile, and utilise the aux input on your car audio for good quality stereo music output, whilst still using the mobile phone input for phone calls. So does the Bury CC9060 handsfree kit, which I now use.
