I have tried to find the answer by reading through this whole thread and still haven't found it. Maybe someone can help me decipher this:
I have a 2008 335i sedan with I-Drive (production date 11-02-2007)
The options i have on it are the following:
S609A - Navigation System Professional
S620A - Voice Control
S639A - Preparation for mobile phone cpl. USA/CDN
S655A - Satellite Tuner
S677A - HiFi sytem Professional DSP
S694A - Provisions for BMW 6 CD Changer
S925A - Dispatch Protection Pack
I listed these just in case any of them affect each other.
My question is: The only thing i wan to add is the USB option (6FL).
As far as i understand (I know i could be wrong) the only thing i need to make this work is the actual 6FL kit, install by connecting to existing TCU and code it to work?
Please any and all help is appreciated.
