My prior 2010 sierra had wonderful bluetooth quality. No complaints from the other end. But i have had nothing but complaints with this new 2013 sierra. Nothing changed as far as a different phone etc. the "other end" says its like im sitting in the back seat while in a tin can. The back ground noise is horrible. On my end the sound is fine. While sitting still they say its ok. I have changed phones now but to no avail. Same problem.
I changed the speed control sound in the radio option, no change. I have contacted the dealership and the gentlemen did find a bulletin about noise cancelation on some phones but it was more directed to blackberries. I now have an iPhone 5. Its hard to imagine that gm changed anything from 2010 to this 2013 since nothing else has changed. Loved the bluetooth before.
