Like the subject line, I'm getting a high pitched whine that rises and falls with engine RPM and the volume resets after each start up.  Sounds like alternator whine.  I didn't get this with onstar prior to the bluestar unit.  The car is a 2008 Corvette and i have updated software and played with the gains.  .
Anybody else seeing this?  Other than these two things, it works great.
Thanks Ted
