Thanks for the hints:
after switching on the ignition WAIT 2h appears
Already twice after a 2-hour drive, when the inscription CODE appeared, I started to read: I clicked the key with the number "1" four times, the key with the number "2" I clicked 8 times but deletes the record and WAIT again
number 4882 loading because 2 years ago the mechanic gave it to me that before he turned on the radio - and I do not accept this number. I haven't used the radio for a year and can't manage.
