Hi guys. I am about to buy a new iPhone and will buy a new stereo for my car.
I have three options, one with Bluetooth + aux, other with USB (iPhone compatible) + aux, and other with just aux.
The aux only is the cheapest one, Bluetooth is in the middle, and the USB is the most expensive.

Good thing about aux is just the price, Bluetooth have the advantage of going wireless and controlling the media from the stereo itself(I think), the USB I think it will charge my phone, also will offload the processing from the iPhone, and I think I can control the music from the stereo too.
Comparing the audio quality, what would be the best option?
And considering the price and features?
The aux price is "x", Bluetooth "2x" and USB "3x".
Thanks in advance.

Unless you have top of the range speakers/sub then you'll be unlikely to notice any real difference in quality.

Is there no option to have a combination of 2 or all of them.

Bluetooth and aux would be my preference

Should have read it properly... Yes aux and BT

Yeah, I think the Aux and BT would be perfect, especially if you plan to use Bluetooth.

Thanks guys, i will buy the bluetooth one, My speakers are just average, nothing too fancy, i'm pretty sure i will not notice if there is any minor difference in audio quality.

I find USB to be slightly clearer, but I'm a recovering music major. I have issues.
