Hi all, I've posted a work-in-progress step-by-step of my experience retrofitting Bluetooth on my E90 335i with iDrive, Phone prep, Voice control, and USB
I have completed part installation and wiring using all stock cabling and install locations, all that remains is coding the vehicle order with $644. I have an appointment with Greg from detailADDICT for next weekend and will update after we attempt to code it.
I have spent $30.84 up to this point, and coding should be $80. I would appreciate comments from those familiar with this retrofit to see if I've overlooked anything up to this point.
