I cannot get the radio to work although the light comes on there is no sound. I have not tried the CD or cassette yet.
If the battery has been disconnected, do you need a code to reset the radio? on 1998 BMW 740iL
yes, you will need the security code to reset the radio. this number should be included on a card that came with the vehicle when you bought it. if not available, you may contact the BMW dealer to obtain this code; have the title handy as you will need to verify ownership to obtain this code.
