Song won't playback after Text or Call?

[yakabod]

Jailbroken iphone 4 verizon.

I connect my iphone to my headunit in my car. The song is playing and i receive a call or text message. The song dies, and I have to press play to continue the song. Why is it like this?

I tried my friend's at&t jailbroken iphone 4 and when he receives a call or text message the song will continue after.

Is there a setting that i have to enable/disable? Or is there a certain app causing this?

Try entering safe mode(hacks off)
Does it work normally now?
