What's the correct OEM remote control for the dual DVD headrest system?

[chrispitude]

Hi folks! We bought a 2006 Yukon XL Denali about two years ago. It came with the factory dual headrest DVD system, but no remote control or headphones. I understand I can use any 2-channel IR headphones, so those are straightforward to replace.

However, different Ebay auctions list different remote controls for this vehicle:

What's the correct OEM remote control for the dual DVD headrest system?

Thanks in advance!
