No sound from AUX in my car? - 1

Added (1). Hello, i have a mustang gt 2014, in the past my Aux was working, but now whenever i want to listen to music through bluetooth, it keeps on disconnecting, and i tried using usb drive, the music in the usb is playing but there's no sound coming out of the car. What could be the problem? I tried listening to my music on my iphone through the aux wire, bluetooth, usb, usb drive, but non is working ( no sound), except the car radio.

Am I spoiled? Be honest, and EXPLAIN?

Right now, I'm 13 and I own a 600 dollar ASUS laptop, an iPod Shuffle, iPod4, iPhone 4, iPhone 5c, iPhone 6s+, PS4, 42 inch television, multiple not used 500 dollar iTunes gift cards, over enough money to attend college, and many other electronic devices, along with a monthly allowance of 460 dollars. Am I spoiled, because everyone at my public school says I'm? Also EXPLAIN YOUR REASONING…

Camera SD card to iPhone adapter?

Is there any brand that makes these other than Apple, and that isn't just a cheap piece of plastic from China? I can't find any decent ones anywhere!
