crap
not sure on the hyunday integration, but on VW, when i press the home button on the iPhone, siri comes through the speakers
but ... when i just press steering wheel button, vw's system comes on (different then siri - thus sux, 100% more)
apple - take note, an option either way in the future pls?
ps: i found the bluetooth integration to be better with siri (then dock connector), but ... it's ******* up on iOS vr 5+ - the volume is either off or all the way up (supposedly 5.1 fixes this). i've decided to stick to 4.3.3 on my ipad & it works perfectly: ff / rw, volume control, etc
