2012 Base Model: Question about included XM unit (Replacing with iPhone dock)

[Joebags]

Hello, everyone! I just bought my first real car, and am loving my Sonic. It's the base model with a very basic stereo; no CD or USB, only aux. However, it did come with an XM unit preinstalled, and I have a question about the wiring which goes from the unit and then slips between the upper and lower front panels. I don't have any of the proper equipment to safely remove the front stereo panel, so I'm hoping to pool into your expertise before messing something up.

Here you can see that there's a power adapter, aux, and antenna that feed into the dash somewhere. But where does the power adapter lead? Could the source be used to power an iPhone dock up there instead of the XM unit? Thanks in advance for your help! I'm very new to all of this.

That is the Onyx radio. It is an aftermarket xm reciever that they installed at the dealer to make up for it not having xm. I install those everyday at Best Buy.

Sorry to answer your question: Does the unit turn on and off with the car? If so they probably got power from the cig. lighter.

It does turn on and off with the car, but it's not getting power from the cigarette lighter (I only know of the one by my parking brake). I'm just wondering what this mystery power source is and if it could be used to power an iPhone dock.

It could be hardwired to it where u cant see it. Hard to say.
