Hi,
I have ordered an Alpine hifi retrofit to install in my E91 from 2007 and have a questions regarding the coding.
I have read the thread and according instructions no coding is necessary, however the sound result from coding the car seem to be better after coding!
In order to code my car I would have to add SA676 into the VO and update the CAS and RAD2 modules correct, or do I just alter all the settings in RAD2 from e90_estereo to hifi and update the RAD2 module?
Thanks
