This Philips CCR2006 is fitted in a Corsa Elegance 2002. Now, after loading CD magazine correctly it won't locate correctly in its slot.The message "magazine" shows on display.It either needs to drop down or lift when inserted or do so when the CD door is closed.It happened once before.A knowledgeable chap in a car radio outlet did something clever just inside the aperture - without tools.Grateful for any help.Thanks.
