e30 radio code rejection

[Ceeker]

Could anyone explain to me why my car won't take the radio code?
I entered the correct code and it let me finish but it beeped after the last number. Tried it 3 times still no luck.
Disconnected the battery and tried again; no go.
Then left the car ignition in access. mode for 1 hour and code is still rejected.
in case you're wondering, sometimes this is what in necessary for the radio to take the code.

Does anyone else have any other ideas on this matter?

thank you.

Wrong code?

[Ceeker]

no no, it's the correct one. I called my buddy at the dealership to check it for me.

Did you try with the car running for an hour?

[Ceeker]

Car running? I never thought about that; I could try it. But from my understanding the ignition should only be in accessory- this is what I was told by a bmw tech and parts personel.

Running or not wouldn't make any difference to the radio. If you are pressing the numbers in the correct order and it doesn't work I'd say something's farked in the radio or you have the wrong code. Even if your buddy says its right. Obviously something is wrong or it would work.

Are any of the buttons sticky or anything, that might be causing confusion to the deck?

[Ceeker]

nope and nope...so I suspect the deck is pooched....
