Hi
I am posting this information as it may save a bit of googling!
I have a recently bought a 2008 XC70 that came fitted with an OEM Volvo ipod adapter.
The first problem is the well-documented "firewire charging issue". This is solved with the following adapter, which will charge the iphone and play the music through the head unit with great sound quality:

The Griffin adapter *DID NOT* work ( although it did for the Dension kit in my
wife's Audi!)
And now for the major downside!
Unfortunately I have not been able to come up with a solution to properly controlling the music. All I can do is select the album before plugging in the iphone - once it is plugged in I can find no way to access the ipod controls.
Voice commands do not work even though the voice screen is accessible by pressing and holding the home button. +(All your other apps are accessible and functional BTW)+. I have also tried both the
FluxTunes and
icarplayer Apps to try and bypass the volvo ipod adapter, but these don't work either. 😟
I have searched for a fix but have not found one.
HTH
