Problems with Cayman 2006 Stereo
 

I have got a the basic audio set up on my Cayman and folowwing a recent service the steroe will not work. It shows the Porsche sign when i put it on but then no other repsonse. radio, cd - none of them work. cd still ejects and loads but does not play.

Any ideas? Does it need a code to reset it? If so there does not seem to be any way of inputting a code and the scren just sticks with the porsche word on it?

thanks for the help!
