Can someone please help.. I've installed the BTB200, I can make and receive calls, I transfered the entire phone book onto the D3 but I am having one major problem. I have no sound!! The mic works perfect, but all I hear from my car speakers is static. If anyone knows how I can fix this, I would really appreciate it. Thx. ps. i've done everything this forum advises in regards to the setting on my BB 8100, yet i've had no luck.
