Is there no way to power cycle the ICE? Traditionally car radios die when you crank the engine, but you could try pulling a fuse Bit less drastic that resetting the ICE.
Also I sometimes find that bluetooth re-connection goes skwiffy after a while requiring a restart of my phone for things to work properly. Then several weeks later it all goes funny again necessitating a restart of the phone.
