CR CRUISER

Do the warning chimes for things such as low fuel, key in ignition/door open, door ajar and the @#$%%^%^ auto door locks are about to lock you out again played through the factory sound system? My 2011 Sierra with non-Bose had all of the warning chimes funtioning as they should. After installing an aftermarket (OGM1) system I have lost everything except the fasten seat belt chime. Of course it's the one I don't want. Is there another way to play these chimes? The DIC still displays them but I don't watch it that closely.
