Hi,

I did it on a 2001 E46 320d Touring, but the harness (pin-setting) of a BIT II is totaly different then form an ULF.

It's possible to reconfigure the whole pin-setting.

But you will have to know what each pin is doing.

You can search different forums on BITII to Bluetooth (ULF) conversion.

Mine is on BMW Treff (google) German Forum but I wrote it there in English.

Beware for your new ULF before you connect it now without reconfigure.

Regards,
Max
