A:Answer The receiver does not have a 3.5mm input jack, which I assume you are referring to as an "auxiliary cable". However, the unit does have a USB input located on the front of the receiver that your phone could be connected through, as well as Bluetooth connectivity, assuming your phone is Bluetooth capable. You can also purchase a "Y" connector to go from 3.5mm output to RCA, via the audio inputs on the back.
