I have a 8330 v4.5.0.186 and when I plug my bberry into the aux jack in my car I get appx half volume and sound only in the lef t speaker. I also have a 3.5mm to stereo RCA plug that I have tried and no dice on the home stereo either. The really goofy thing is that when I plug a set of headphones (regulare stereo headphones not bb headset) it works great. Any ideas?
