Loose wire going to the radio would be my first guess. Also possibly a bad head unit.

The battery voltage fluctuations are normal for this car. Also your idle is normal - 700 to 900 RPM is normal. The fan blower could be an issue but mine also cuts in and out to cool the engine. I do agree with Jim that you need to get your car into a dealership ASAP as it sounds like your electrical problem is getting worse. Hopefully it's just the negative battery cable, which is an easy fix.

Did the new cable resolve your issue?
I had the same problem a few days ago and today it happened whilst making a turn and I lost power steering for a few seconds and then intermittently after that. I called onstar but their diagnostics were okay. So they set me up with an immediate appointment (kudos onstar) with the dealership down the street. I told the dealership guy what had happened and he checked the battery terminals for corrosion . While he did that I told him about what I read here and he said there was no such thing -_- so I don't know if they're trained to sat that or if this is the start of a very bad experience.
