I just got this cd radio. It's the newer version in the e36. I put it in my 525 and I can't input the code right.


Now, my old tape radio, I punched the 5 digits code and it worked fine. The seller wrote a 6 digits code on the radio and I believe it is the code but does anyone knows how many digits these units need. I did a forum search on the subject with no luck.

It reads "code" with 4 bars so I'm guessing 4 digits. But is there something you need to do before or after you input the code. Also, it doesn't beep, you can actually write the numbers on the unit so I'm guessing you write the number and touch a key to validate. It's the second time the wait code appeared and I have to wait 1 hour again...

Am I missing something?
