Answer 1

I have an iPhone 5 and every time I get into my car, as soon as my iPhone connects to the bluetooth or if I connect the USB cable, the music starts blaring through the car stereo, even if the radio was off. If I am using any of the navigation apps on my phone (google maps, waze, apple maps), and I happen to be lucky enough to have the voice directions working (that's consistently inconsistent), the music will frequently start by itself during navigation, even if I didn't turn the music on. Sometimes the music and navigation voice over will compete with each other at the same time. Sometimes they both go totally silent. Sometimes I'll hear only music. Sometimes only the voice directions. And if make or receive a phone call while the navigation is working, as soon as the phone call ends, the music will always take over again, even if I didn't have the music on prior to. I've checked and re-checked every setting on my phone, in my apps, in my car, and followed all of the suggestions I've found online (note to Apple - there are tons of posts on this topic), and nothing works.
It seems like there should be an easy software fix for this, or at the very least, options to:
prevent the music from starting automatically every time you connect with a cable or bluetooth (insanely annoying)
allow voice directions to temporarily mute music, should one choose to be listenting to music and navigating at the same time
just listen to voice direction - no music!
Better yet, how about just provide options to let the end-user decide when to listen to music. 
For a product that is supposed to be "intuitively easly" and/or "just works", this level of dysfunction shouldn't be acceptable. Come on Apple - what are you doing to fix this???
