I know the recent-model (i think 2011 or 2012) Hyundai Elantra works well with my 920 over Bluetooth. (you'll need to either hold the call button or use "Call Cortana" to get to Cortana - audio and texts come in as expected with Cortana asking about whether to read it and HERE Drive directions read out as well.)
Don't know about the Sonata which is the other family car, the one I haven't tried, but I dont think it would be too different.
Don't think the USB port works though. (Hyundai's is weird and selective to some Apple things)
AUX in will work since its a standard, but I prefer BT.
