No SOS and No AUX input
Hi
This morning when I started my car I was greeted with a no SOS light on my CCC unit and dashboard. I have CCC sat nav, with usb and aux in armrest. 2007. I have also lost access to selecting AUX input on my CCC. It's just greyed out. I still have full radio, BMW Chimes, and all other sounds/ audio works with no problem. Can someone please advise what's the way to resolve this? Last edited by Yam_440i; 12-25-2019 at 08:10 AM.. |

Ps. I have checked my trunk and I seem to have only a TCU unit under my trunk cover. I will order a bypass to eliminate this as a problem but should there be a MULF unit here?
Also is there anything else I can check? My symptoms are different to others in the sense that everything else is working just apart from the AUX input. |

The mulf 2 hi which does the usb is physically under the TCU.
If you have Hi Fi sounds will continue to work with a Most Bus module out. Early idrive cars also have a Most Hub in the drivers kick panel. (US driver side) https://www.newtis.info/tisv2/a/en/ Euro configurations may differ from what we know here and the driver side is the left side from the US perceptive. |
