I've spend months considering this problem. CD ok but not the radio. Like you I thought at first it was the aerial bit it wasn't. Eventually  I had it repaired through a garage. I think it cost me over £150. More than a year later it failed again.  There are replacements on ebay, usually from breakers,  which  seem to go for about £80 (watch out for duds and frauds). I have been looking to replace it with a radio that you can connect an mp3 player to but may end up resorting to a replacement 6006E via ebay.  One added complication is I have a hands free in the car and my new phone does not fit the cradle. In this the best of all possible worlds...
