Hello, can anyone explain to me why i am unable to release my cd6000 stereo from the dash in my 2004 mondeo. I've got the 4 release tools but can only get 2 to lock in place, everytime i think the other 2 are in they pull out when i go to pull. Does anyone have another way of getting the stereo out so i can fit my Parrot handsfree kit. Many Thanks
