I have a 2007 infiniti QX56. For years I had my iphone 3gs connected via bluetooth with my phone. When i received a phone call the phone rang through the cars speakers. However, when i upgraded apple OS on my Iphone 3gs a year or more ago, the phone no longer rang throught the cars speakers. I believe it was when i moved from OS 3.x to 4.x. I have tried un pairing the phone and starting over. Nothing works.

SOURCE: bluetooth/radio stopped working

In first instance try to disconnect the unit from the mains and reconnect 15-20secs later 8 times out of 10 it helps. otherwise you might need to reprogram the unit processor which is more complicated and requires knowledge and understanding of electronic principles, assembler, also some devices to perform the task.
Otherwise I'm not sure about exact model of your ECU (computer) but in some cases it also gives the access to reprogrammable radio unit, so in this case laptop, one simple program (u can find it as free downloadable .exe file) and special diagnostics cable wuold sort everything out. But as I said not all ECUs offers such an option. And if you'll go for this step you need some knowledge about electronics and soldering as you'll have to build the cable I mentioned, as tu purchase one would be quite painfull for your vallet.

Hope it helped although if you need any further information just drop a line here.

SOURCE: Unable to connect my iphone 3gs to the Parrot CK3000 Evolution.

You need to reset the Parrot first.

Hold down red and green buttons together until she tells you that the memory is being cleared. Then she will prompt you to pair your phone.

Then, and only then does the Parrot allow the iPhone to pair, and it will bring up the code prompt for you on the iPhone.

You won't find this written down anywhere on the Parrot site.

I have the same car. The dealership wanted to charge me $155 to go into the computer and give me the passkey.

One of the techs just told me how to find it myself:

Inside the trunk, on the left side behind the DVD player, there is a box that sits at a 45 degree angle. Right above that box, there is a box that is shaped like a VHS tape. Unscrew that box and on the other side you will see bluetooth PK: and your four digit number.

That saved me $155 dollars and now I can talk hands free through my car.
