Hi mate same system as mine(in fact that is my pic)..have you got c.d discs like these:
One is the map reader c.d and the other is the languages c.d they come with the car when new.??
The slot in the glove box is for the map reader c.d only,and the language c.d to set up system,
if you havn't got them they could cost you at the dealers the map c.d is around£150....
You can get them off e-bay but be aware of copies.
any more info don't be afraid to ask mate.
