The radio and navigation unit in my 2007 VW EOS was working great both with the wired Aux in put in the glovebox and with a bluetooth adapter in the IPOD dock of the center console. However, it suddenly started displaying a bogus "Check Magazine" error message. This occurs each time I select "CD" and attempt to press the button for the Aux option which no longer displays. I don't have a CD changer so I don't understand why the radio is displaying that message and no longer giving me an Aux option. Has anyone encountered this problem?
