I have a problem with my 9088A changer. i have a vw gamma radio. the changer didn't find the folder CD01. he is starting with CD02 (CD02 is showing on dispaly from the radio). But it is not the folder CD02 it is the folder CD01. And the folder CD02 is complete missing. The dip switch is correct to the maual instruction VW 8 pin, on on off off.Do you have any idea what is happend?Kind regards
