Surprising that the Y cable is still being used in 2011 cars w/o combox.

All the more reason to have the retrofit done and have bluetooth streaming too.
It is because of Apple.

The OEM "Y" cable works only with the iPod/iPhone because it uses the iPod/iPhone analog line audio output as the AUX input. The USB only serves as the control interface medium. This was done as a patch to allow DRM songs to be played but not copied.

If you have an Android/Windows phone or USB stick then the USB port handles both control and audio digitally, regardless of Combox.
