combox retrofit
Hi guys,
I am trying to retrofit a bn2000 combox to accompany my CIC. My vehicle is a 2007 E91, the car came prewired VO S640 and originally came with CCC pro Nav Japan. I have managed to retrofit CIC however I don’t seem to have any power at the prewired TCU connector. I have checked fuses 17,26 and 27 all which have the correct fuses. Any idea which other fuse it may be? Kind regards Zaman |

I have repinned the tcu connector to a new 26pin combox connector, I have used both pin 17 and pin 36 from 54pin housing. My issue is that pin 17 has no power at all, I have looked at the fuse box in glove compartment and the fuses relating to Bluetooth telephone all have the correct fuses in place |

The pre wired plug only had these pins attached in image. I have managed to repin all but two of them. The blue/black (pin 12) and the white/black (pin 32). Repin Diagrams on this forum and others don’t show what these pins are used for so I have just left them out for now. I have only managed to use 5 wires ( power pin 17- pin 1, ground pin 36 - pin 14, thre wires for mic pos,neg and shield). From testing my issue with that power pin 17 is dead (has no power). Cheers |
