I've taken my car to BMW dealer and they were unable to diagnose it, just charged me $175. Figures.


Taken car to another shop, they've replaced battery and after about 1 week of trying couldn't figure this out.



So , as before, colder it gets - longer it takes to for radio to start working.

I suspect CIC module, since on a cold start at about 0F CIC reboots several times before "heating up" and starting to work.



Going to open central console and heat up a CIC just to get it worm. Hope this helps to pinpoint the problem.
