I had the same problems with my BB Tour. I just replaced with Droid 2 and now everyone can here me great with no background noise. I think some people are having the problem because of the BB.
How come we have the outputs on the 90BT if we can't use them? What can the ouputs be used for? How does the Pioneer XM work? Does it cut out going under overpasses or under tree's?
Can I wire up my XM Skyfi II to work with the 90BT? If I can't does the Pioneer XM have the sports/stock ticker option? I really would like to use the portable Skyfi II so I can use it in my truck and boat.
Thanks
