Can't get Ipod to show up on display

Just got a 2012 c3, and I'm trying to get my iPod Nano (4th gen) to show up on the display as an iPod, controlable from the steering wheel and display. The manual says this iPod model is compatible. The iPod software is up to date.

If I plug my iPod into the AUX with a standard audio cable, it plays over the speakers fine but the display shows only "aux" and has no controls for it. If I plug it into the USB with an Apple cable, it doesn't plays over the speakers at all, and the USB doesn't show up as active on the display -- it's grayed out. I tested the cable elsewhere and confirmed it's fine.

Anyone know what I'm missing?

 

Yeah, I figured as much. Just can't figure out why it doesn't register at all when plugged into the USB port.

 

Great suggestion; thank you!

I've already tried two different Apple cables without success. So I tried a thumb drive with mp3s on it just now, and that worked perfectly (sound and controls).

So I'm figuring at this point that the issue is related to cable or iPod model compatibility, though I'm at a loss as to how (since the gen is compatible and the two cables I tried are OEM).

 

I'm thinking now it is definitely the iPod software. Tried connecting an iPhone to the USB, and it came up as an iPod and worked fine. Since the software on my iPod is current, I'm stumped. Anyone have any suggestions?

 

Solved it! I'm recording the solution here, should others ever run into this.

If all else fails, reboot the iPod. (On the 4th gen, you do this by holding down the Menu and center button at the same time, until the Apple logo appears.) I am guessing that, in the plugging and unplugging, I must have 'confused' the iPod, and it stopped communicating through the cable. After a reboot, perfection.

Thank you MBRGuru and Further for your help.
