iPhone: How to keep music playing when iPhone is removed from a dock?

I’m wondering if anyone knows of a way to have music not stop playing when the iPhone is removed from a dock?

I have a dock in my car and whenever I hit a bump the iPhone loses connection to the dock then immediatly recconects to the dock. When this happens I have to hit play again because the music stops playing as soon as it’s disconnected. My phone is jailbroken so I don’t know if anything can be found on cydia. If anyone could help I would really appreciate it.
