My girlfriend owns an Opel Corsa B. She bought the car radio from the manufacturer Medion and I then also installed it on the WE. Works also so far, only the device can not save the transmitter and you have to turn the ignition key so that the device gets juice. Who can tell me which cable I have to plug from the radio into Which PIN number from the plug of Opel. Image I attached from radio cable. Thanks to all who can help me already in advance. M all
