Retrofit MULF/MULF2

magma · 02-19-2026, 10:46 AM

Hi! I decided that I wanted to add USB integration to my E90. Currently I have a 2006 E90, only a TCU with Bluetooth (no iDrive), and I am wondering what parts and wiring I would need to do to add the MULF. This is all in preparation for an eventual retrofit to CIC. Any help would be appreciated!
