Hi all,
Having a tough time troubleshooting why the USB/Aux in my center console are not working.
Not trying to get iPod/iPhone control setup, I just want my aux input to work.
Here's the symptoms:
- BMW Professional Radio shows Tuner, CD, and Aux In, no USB option
- 12V in center console works
- No voltage/power via USB (i.e. phone or iPod doesn't indicate 'charging')
- No sound from aux, no crackle when plugging in/out
Having done some reading, I am hoping it's just the fuse for the ULF unit, however I am having a tough time figuring out which fuse/circuit is responsible for this.
Another idea could be the radio itself wasn't coded properly (i.e. missing USB option).
Any thoughts?
