Help, I took my husbands car in because the turn signal was clicking too fast. The mechanic told me the battery needed to be replaced. Now we can't listen to the radio because we can't find the security code. Can anyone help, the radio is a BMW Business cd and the serial #29965225. Please help, Thanks
didn't actually take the radio out to get the serial #. i used the trick of pushing the m button to get it. there were no letters only numbers. 29965225 was the only thing that came up. don't really want to take the radio out if i don't have to.
