CD30 / CD40 Decoding. - vectrac20tsri - 16-01-2019 The security code starts at 3E8 and is 4 bytes long. 0x95 xor the first byte is the 1st digit of your security code. 0x3F xor the second byte is the 2nd digit of your security code. 0x4E xor the third byte is the 3rd digit of your security code. 0x6A xor the fourth byte is the 4th and final digit of your security code. Late cd30s with usb and cd40s use the same algo just start at a different location 4E4. Not sure how useful this is or if it has already been released but I have had soo much from the site just giving a tiny bit back. My dad is currently breaking a astra h so If I can get any more modules I'll post the info on them as well. RE: CD30 / CD40 Decoding. - evo1 - 16-01-2019 this address on e2p??? post one file for example...... RE: CD30 / CD40 Decoding. - bank - 16-01-2019 Everything is correct, xor is needed to decode. Also, radio can be divorced by writing appropriate content in 3e8-3ee (or 4e4-4ea) Also this way CDC40 Opera and DVD100 Navi can be decoded RE: CD30 / CD40 Decoding. - Arbe - 08-02-2019 Use this XLSX Rule 3: Do not Post Links on the Board!
