BMW Alpine radio links coding
I have spent a lot of time researching how I can decode my radio. I only have an serial # F20133216A, BMW can't find code with this serial. It appears from researching, press - and prog at same time displays model, I have an BMW Alpine2 or Alpine3, the last digital shows partial, this radio common for 91-95 BMW 325i series. Further research tells me that I have jumpers and I found the model, CD ready CM5903, by researching the chip #, 51T25160W03 568, it also told me my code is 5 digit, 11111-55555. I looked and find on the board an area labeled TD 1-6, #3,4,6 are jumpered by solder. From a decoding software calculator I found, Alpine 6 links with links 3,4,6 the code should be 33515. Doesn't work... I am running out of options, any help, please. :?
