hi gambit thanks for your reply, i armed myself with an assortment of tools, grinder, drill, 7ilb hammer, but i decided to try the "SKY" trick first and reset the unit, " undone batt. terminal" left it a few mins. connected batt. again and what do you know , the cd mechanisim started wirring away and reset itself, so before you use gbh on your player, try the reset first. cheers michael, :D :D
