I recently got my 2010 Prius V with Nav. I have some strange noise the person on the other end hears when using my HTC Pure (Diamond II) via Bluetooth. Some details: - BT Audio streaming works perfect - A LG Shine has no trouble at all - The HTC works well paired with a different BT set - The noise is kind of random and does not stop when the car micro is muted but stops when the phone is muted. I attached a sample of the noise recorded from the other end of the line. The car was parked in a quiet place no background sounds at all. Has anyone ever experienced this? My next step is to try the HTC at the dealer at a different Prius. Anyone with the same phone / car combo? jakman
