Crashes 4S

If not connected the opens and appears to work, but connect with Bluetooth or by docking and it freezes on the existing screen. No function can be chosen from the bottom set of icons. Closing and relaunching the app causes a crash after the splash screen. Not worth the 4s update.

The worst thing is that this system sounds great compared to the majority of docks and beats out some car systems.
