Interesting. My 'Grey' SVX has the CD player in the boot, mounted just behind the seats and sitting on velcro. I've never had any problems with it at all. But, it is 2001 technology not '91 technology. I might have a go at cleaning the @black' SVX's original fitment CD player as suggested earlier in this thread and also remount it on velcro to see if thst makes any difference. I will let you know.
