Hi guys.
I have a radio Audi Chorus M4.
I am a little bit confused.
It has an MCU with 3F71L mask but I dont find cross reference anywhere.
The serial number is: AUZ1Z2Y69280206.
It also has an eeprom near to the MCU that appears to be a 24c16, it hasnt nothing saying that but it appears to be.
Anyone can clarify this doubts for me and tell me exactly what I need to read in this radio?
Thanks to all.
Best Regards,
Nuno

Hi friends.
Thanks for your replies.
I need dump to write in the MCU because with Upa it reads FF all the memory.
Please, if someone has dump for this radio and knows the code, share with me.
Thanks to all my friends.
Regards,
Nuno
