I'm not sure if it can be retrofitted if you don't have performance audio.

It is used as an iPod/phone/ connector, as well as USB mass storage for music and finally for updating the satnav

But I have performance audio:aux only,two speakers only on front doors,no bluetooth,no usb,no amplifier...I think that's performance.
That's why I wonder what's that USB is...

4 specifications levels of infotainment equipment:

Level 0 - Performance (Radio/CD/Aux, 5" screen, integrated amp)
Level 1 - High Performance (Radio/CD/USB/Bluetooth, 5" screen, 4-channel AUD amp module)
Level 2 - High Performance Multimedia/Nav (Radio/DVD/HDD/USB/Bluetooth, 7" screen, 4-channel AUD amp module)
Level 3 - Premium (Radio/DVD/HDD/USB/Bluetooth, 7" screen, 5-channel AUD amp module)

The USB connection in Performance audio is for updating the unit only by Volvo service..

You're killing me....
Are you sure?cause on the same wiring diagram when refers to premium audio seems that usb goes on IAM not ICM.
The audio system ''Level 0 - Performance (Radio/CD/Aux, 5" screen, integrated amp)'' was the basic audio unit and does not include usb for music. The premium systems (Level 1 - Level 3) have USB for music that's why is connected to IAM unit..
