For anyone attempting this retrofit for Bluetooth with the MULF2 High module. Meaning your car came with just S640A option. 2 things to note.
  1. The mulf2 high module is used for USB as well; therefore when it comes to coding, add both S644 and $6fl to VO. Even if you do not need USB (Yet). The 6fl option tells NCS Expert that you have mulf2 high module and will call up the appropriate files to perform a reset for the mulf2 unit. i.e no errors.
  2. Your S640A (Phone prep) means the car is prewired for a TCU not the MULF2 unit. Rewiring is needed in the fuse box area for the microphone to work.

This worked in the blink of an eye for me. Radio is 2URAD as well.

Thanks to everyone who helped on this retrofit. alexwhittemore Thank you sir!
