New 525i Owner Radio Code Problem

[RIPDOTCOM]

I picked up a 1993 525i Sunday and it is simply awesome. Anyway. i have been reading through the forums and fully understand what I am supposed to do about the 5 digit radio code. I have the business cd system. i went to the local dealer and gave them my serial # off of the system and they gabe me a 5 digit code for my unit and it simply does not work. I have input it 6 times total and the message goes back to "code Wait". Am I missing something? I am not 100% certian that this system is even an alpine as i thought it was a blaupunkt. Anyway, if anyone has any suggestions please post them. I am probably going to pull the system again and bring it to the dealer and have them verify that the code they gave me is correct.

If you imput the code wrong...or the system simply does not accept it... you need to:

1) Pull the both the + and - leads off the battery and short them together for about 2-5 minutes. This will discharge the capacitance stored... and should let you re-enter the code after your reconnect the battery terminals. Be sure to read about how to enter the code properly. On my 1992 model, I think its:

A) Turn the radio on
B) Enter the code numbers and then press code on the OBD. If you are good to go you did it. However, if you hear a "beep" before you finish entering all 5 digits, then start over from the 1st digit. If this does not work.... Leave the battery terminals off overnite, and try again.

.... If that doesn't work, you need to remove the radio from the car and give the serial numbers to the dealer. Then they can give you the right code numbers to enter. I believe the dealer will give you the code numbers for free if you pull the radio out of the car.

Good luck.

They must have given me the wrong code because the serial # I gave was

#bp027319932114 which denotes by the first 2 letters that it is a blaupunkt and they gave me a code for an alpine :(
