Because of where it's placed your doubting that its an aux cable?

That's a 3.5"mm aux input =P

I'm 95% positive thats your rear aux input, regardless you can plug an aux cable into it and run it somewhere and if by the remote chance its NOT an aux input then you'll have somewhere else you can continue the cable at

Only other thing I could see it being other than an aux input is a microphone input if it has bluetooth or mic tuning capabilities.

Okay it wont let me post a link to the manual but it is the "Steering Remote Control Interface Connector" if I could post the manual it would help out a ton has the whole wiring diagram but just google your HU and its on alpines support section of their site.
