Just aquired an A4 Saloon SE Tecknik 2012 yr. Delighted with the car but do not seem to have any means of playing my range of ITunes, since the CD has a locked in Sat Nav CD software.My music files are all on PC or CDs. I am told that there is not a docking facility for an IPod Nano 7th generation available. My car has a USB connecter lead.I hate to say this but I am already missing my BMW 6CD auto changer. And at 90 this will no doubt be my last car change. Your comments would be appreciated.
