[i5000]

I Try to decrypt some Hex data file from a Car Audio Display, CID Display from Opel, VDO Siemens, I Have Read the Eprom which i see the first 20 bytes for the ECU ID Numbers as Clear-text, This Numbers shows Part Nr. Code Index Version and Number, Manufacter Data. etc. But the Rest i cant Read as ANSI ASCII. I Think its XOR encryption... i Try Brute-force, but without success!!! Can anybody Help me here :) ? XOR Key ? or its other decrytpion? Sry for my bad english :)
