FYI--the factory sound system may sound incredible to you it is a long way from the quality you can have with a reasonable investment.

That said, are you experiencing 1-2 and 3 regardless of how you are using the radio? Do you have DSP? Is the engine restart the only way to change how it is operating or does it just change on it's own sometimes?
