Silver Member Username: BogegeBG Post Number: 418 Registered: Dec-10 | Wolfy2u BMW CM5907 Find jumpers of 7 groups, Group 1, 2,3,4,5,6 , 7, on the circuit board. To short all groups, code will be 12434. (Notice: when we say to short the group(s), means the other group(s) open. Find 0.047V/5.5V battery on the circuit board, open and discharge it then power audio and enter code) |

This unit is a BMW factory cassette/stereo from the late 1980's. I think it was made FOR BMW by Craig, but I'm not sure. Again, model #CM5907, serial #A71154873D |
