I have a blackberry that syncs for my phone. I use my iPhone for music playing. Some of the time when I get into the car, it works perfectly (ie, BB is connected for phone and iPHone for BT music). However, sometimes it only looks to the BB. Is there a way to fix this? Ideally, I would like to not have the BB registered as a media player but can't seem to figure this out.
