I am asking this question because I am planning on buying the Bluestar system as I never use onstar. When i was in my free trial of Onstar I could barely hear when the attendant was on the line.

My question is if it is possible to turn up the volume on the Bluestar? I have the Monsoon sound system and factory Nav, but I don't think the nav volume controls the onstar volume. I am worried that the Bluestar will not be loud enough and useless when i am driving on the hwy.

Any thoughts or help is appreciated.

 

The radio volume controls the Onstar volume. You can blow your ears off if you have it turned up.

 

egroegart is correct. The OnStar volume is controlled by the radio dial in the vehicle. Let me know if you have any additional questions about OnStar.
