Whenever my iPhone is connected to my STS via Bluetooth, there is a loud buzzing sound that comes on right before the time when the first call or two is made. Anyone know why it makes that annoying loud sound and how to fix it?

Thanks!

Everyone that has an iPhone and an STS has this problem. No known fix at this point. There has been quite a number of discussions in this news group and the one for the STS-V.

I have ugpraded my nav system and my phone to the latest software versions and it still does it. VERY annoying!

I have the same problem with a Treo 680. There is another thread with bluetooth and Iphone that has more details.

Regardless, no solution as of yet.
