Hello municipality, I drive a Volvo C30 2.0D Powershift BJ 5/2010 in Momentum equipment and High Performace Radio. So far the iPod function of my iPhones worked without any problems via the normal iPhone USB cable. Yesterday I now have a new firmware installed, from 4.1 to 4.21 on the iPhone and since then the music no longer works…. The iPhone reports that the device is not supported and appears in the display of the radio, “Unreadable” when I select USB as input source. Did you also have this experience?? Can I reset the iPhone firmware to 4.1 or is there an update for the High Performance System? I must anyway within the next 14 days for 20000 inspection. If there is an update of Volvo, this can be directly recorded. Thanks for any tips in advance. Grumpy
