Anyone else have the following problem? When I press the OnStar button, the thing actually works, the SID says "Connecting to OnStar" and the woman announces connecting to onstar - and then nothing, nothing ever happens and eventually the thing just hangs up. Same thing happens when I try to make a phone call - the SID says calling, then nothing happens and even with four bars, the calls never goes through. My OnStar has worked once in the last six months - and for one day I could make calls just fine and the Onstar went through just fine. What could be the problem - and if so, any smart ideas on a cure?? Thanks one and all for any advise.....Cheers.
