Galaxy S4 Streaming Problem

[tys123]

I just bought a Galaxy S4 coming from a iPhone. One of the main things I do with my phone is play music through my car and home audio which is a problem because with the S4 I cant do this as it seems like everything is designed for iPhone. When I connect my phone to home audio via usb and i play the music on my phone nothing comes through speakers and the music just play through phone and when I connect it to bluetooth audio in car the same thing happens.

I play my phone through these 3 things primarily:

1) Integra DHC-80.3
Integra DHC-80.3 Surround Processor and DTA-70.1 Amplifier | Home Theater

2) 2012 BMW 7-Series (via bluetooth audio)
BMW 7 Series Sedan : Showroom

3) Onkyo TX-NR509
Amazon.com: Onkyo TX-NR509 5.1 Channel Network A/V Receiver: Electronics

So is there anyway to fix this, or should i just return the phone and get iPhone 5, also aux isnt an option because the receiver dont have that connection

for home stereo try a audio y splitter cable as far as bluetooth with the car i would unpair and then re-pair it and see if it works bluetooth is bluetooth shouldn't matter the phone model.
