ı have bmw 2004 model e63 645 ci. On monıtor it says “ Head unit not Coded correctly” White Does it mean ? And how can this problem repaired ?


Unfortunately, your car needs to be encoded and it will cost you some money.


Did you change something before this in your car? maybe change the navigation or CD system etc?


I know a lot of people who had this problem in their 5 series,


Do not try to code this yourself or check something online. Take it to the dealer for proper encoding. Be warned, that is the encoding is not done properly, it will end up causing more issues. That is why I am recommending you to go to the dealer for this.


It shouldn't take more than 10-15 minutes and will cost you less than a $100.. hopefully

Yeh so basically the message is saying that you have some problems in the code. You will need to reprogram this. Did you do something to the unit? change something? anyway, the above comment is correct, you will need to get this professionally coded.
