Old Audi Chorus Radio Code Please

[Tuneless]

Hi, I just bought a 15 year old Audi A6 which still has its original radio cassette player, but sadly in Safe mode 🙁.

I would be VERY grateful if anybody could help me out with the code so I can use the radio at least until I can afford to buy a better system?

Many thanks in advance.

The sticker on the side says:

GRO Chorus 4B0 035 152 C
9.18422-81. G.HL 67-00

AUZ2Z2B1196152 02/02

Thanks anyway!
