Hi folks, I have the above 6-disc changer but it's married to a vehicle (so unknown VIN) and can't divorce it. I would like to have it married to my current vehicle so I can do some CANBUS hacking with it (monitor the messages, and learn how to emulate a CD changer made with Atmel ATmega328 and some can interface chips).

The dump from the S220 (93c56, in 8 bit) is attached.

Here's my VIN.
YS3DP55G6Y7009099

I'm sure erold will chime in

I used a BusPirate to connect to the chip and dump it. Will have to learn how to use it to also upload the new code...

Thanks!
