There are several videos on YouTube where they show how to use it, the fact is that according to the radio model that is mounted in each country, the extractors change shapes. There are picks and arrow type. Better a picture helps, or put brand and radio model.
Thanks, Another question, because the radio turns on alone how to solve this problem even turns on after removing the key.

Perform a test, when you turn off the engine do not remove the key, perform movement with the same turning it without activating functions to see if the radio turns on, if so there is a problem in the cylinder or contactor. Anyway I suggest you consult the autostereo forum to have a technician diagnose it.
