Opel Corsa C 2001: CDR 2005 VDO Radio Unresponsive After Selecting Coded Station

Hello. Recently I bought an Opel Corse Cz radio as in the topic. Some time the radio turned on the ignition and turned off by removing the key from the ignition. Yesterday, when selecting the coded station, it searched for it endlessly. When I tried to change with the button on the steering wheel, the radio stopped working. The date appeared on the display . temperature and time. Attempts with buttons on the panel ended in failure. The car has not been disconnected from the battery. The radio has a damaged potentiometer. What is the cause of this fault and how to restore it to its original state?

Hello. Try to find the "reset" button. Often it is a small hole in the housing through which the internal contact is pressed in for a few seconds with a match or a wire.
After this operation, the radio should return to its factory settings.
Greetings.

Thanks for the response. Maybe a friend will direct me where this reset is located. I looked around the entire radio and I can't find it.

It is different on different radios - you cannot consult the radio manual - maybe on the Internet. On my radio it is under a removable panel.

After soldering the damaged potentiometer, the radio works. There is a problem with reception when the engine is on. The radio is quiet and does not receive clearly.

Hello. I am asking the moderator not to delete this post. I am setting up a new topic because in another I did not receive a reply. The defect is as in the topic. The radio had a damaged potentiometer. wheezing.I would be grateful for any information.
