I've posted before about my terrible radio reception. My Onstar seems to be affected also. The connection to Onstar does not come in clear and it is difficult to understand what the person is saying. In addition, the few times I've tried the turn by turn, the downloaded directions are so low in volume that you have to struggle to hear them (even with the radio volume turned all the way up). This is my first vehicle with Onstar so I have nothing else to compare it to. I can't imagine it's supposed to be like that. Anyone else have the same problem with the Onstar?
