Hello I am new to this site but I recently purchased a 2011 Audi S4 Prestige, I am having trouble getting the radio to come on. The car will play a CD fine but when I switch to the radio, the Media (CD or SD) continues to play and when I select a radio station nothing happens. I am new to Audi's so maybe this is a simple fix but please help. I am sick of listening to CDs. Also am i able to stream music through Bluetooth? It has an Iphone 4 cable in the glovebox but thats all.
