Radio exchange help

[cla]

Good morning everybody . I'm from Brazil and I have an Audi A4 Avant 2005/2006, it had a radio with a factory cassette with 2 din PHOTO Nº 1), now I'm putting in the radio from the A4 2007 with a 6-disc CD (PHOTO 2). Can anyone tell me which socket I can put on it to work correctly without having to adapt it? I've even made a connection with a socket I bought on Aliexpress, but the radio doesn't keep the memory and doesn't turn off when I remove the key from the ignition, and the button lights don't turn on either. If anyone can help me with the correct connection I need to make, I would like to thank you all in advance, a hug.
