Bt Audio to car stereo stutters.

I've tried to stream my music from my iPhone 4 to my Kenwood car stereo via Bt Audio/a2dp. And I get this type of stuttering every now and then, often every 10th second. Sometimes more often and sometimes less often. It not really stutters, it's more like fading in and our during half of a second.

I have tried everything, shutting down 3G, mobile data, GPS, Push, Mail checking. And it still stutters.

And then I got the brilliant idea to try flightmode, so if I enter flight mode and then enable bluetooth it will work flawlessly. And even more confusing, after disabling flight mode with the bluetooth connection still playing it just keeps on playing for hours without stuttering.

But if I shutdown my carstereo so I have to reconnect the bluetooth it starts to stutter again. And the only way to get rid of it is to enter flightmode again. This really must be some kind of software bug.
