Everybody tells me my Bluetooth sounds like I'm in an echo chamber...

[TowX]

Installed the BSW BT in my '04 about 3 months ago. I'm now being told that my conversations sound like I'm either in a cave or echo chamber. The same phone (Razr) works fine in my other BT'd car. Any thoughts? And of course I'll call the good folks at BSW after the holiday.

Also- to get around the echo, I keep trying to disconnect from the car, but the phone only stays disconnected for a second or two then the BT snatches the call back. Don't want to delete the link because I can at least take conference calls from the car where I only have to talk for a few minutes per call, but I can't figure out how to disconnect.
