Hello guys,
i know this is not the core business here, but, by any chance - anyone tried to dissasemble the original Audi night vision control unit, and extract firmware?
Im trying to retrofit it into a non-compatible car - Q7 system to a Q5. Everything works, only the image transfer does not occur (but it throws out an error after transmission attempt - also calibration not possible after tool is found).
one of two likely applies:
1) Virtual cockpit cluster does not have HW or SW on it (unlikely, as it has all adaptations, codings possible, HMI parameters are identical,...)
2) NV Control unit, against vehicle gateway or cluster requires a handshake (chassis ID/VIN; VIN mask - this was the case on the non-encrypted modules) -> More believable, as there are many NV control units for different audis, and even for other in the VAG concern: vw's, Bentleys, Porsche,....
i do have the original firmware, but its encrypted (likely AES, no compression). There is a chance, that on the board in the chipset the decrypted data could be downloaded. For a known fact, flashing procedure on car opens protocols for decryption and checksum actions.
if anyone can help, let me know.
Sorry for asking non-topic related question, but im running out of ideas

regards, M
