Default [Q] Bluetooth Messaging in Car

Maybe someone knows something about this. Running cm 4.3.1 and currently I can view and hear incoming text messages via bluetooth in my car (ford sync). While running a kk rom although it asks to confirm bluetooth map access but I never see any incoming messages and settings indicate that my phone doesn't support this feature but of course it does since it works with 4.3.1 just fine. is this a known issue with kitkat?
