golf / vento mk3 sony radio cassette

[vwnige]

does anybody know how to remove one of these,i have a new one i want to put in but i cannot get this one out.

[SYSTEMSEIKO]

take off the detachable front and black outside surround, if my memory serves me well i used 2 blunt knives to slip down both the left & right hand sides to release teh anti theft catch, crude but works a treat, hope this helps.
