I have a problem with my DKU-5 cable.

i plug it in my nokia 7210 and it appeared in my screen "Accessory not Supported"

I find out the my sister broke it before without my knowledge.
she brought to the repair shop and now my cable is not functioning.

"Accessory not Supported"

Could anyone have a DKU-5 and show to me how the wires connected..

Pls help.

I will be the to repair it.
