I have a 2004 XC70 with HU-803 stereo (and no external changer). I've read up on the various options discussed in the past for iPhone integration and it looks like the iMIV and USA SPEC PA11-VOL were the units of choice in the past. Are these still the recommended ways to connect or is there anything newer on the market? In addition to a good input for audio from the iPhone, hands-free Bluetooth would be nice to have.

Thanks in advance.
