i recently spent a lot of money on this car. i replaced the is board battery and other stuff not related to the radio problem. the radio worked until i repalced the battery (bmw dealer) yesterday. i am unable to decode the radio. i know the code but the car will not accept it. the dealer told me to wait 1 hour and try again. no luck. any ideas will be appreciated.

thanks,
mo

Its actually a lil over an hour that you have to wait, also did they mention that the key must be on and the radio on and displaying "code" during this time?
If you didnt do that then try again.
