Does anybody know if the Moto X is compatible with the USB cable with audio that Motorola included with their car dock for the Droid RAZR (MAXX)? See the sixth photo here Amazon.com: Motorola DROID RAZR MAXX Vehicle Navigation Dock with Rapid Vehicle Charger - Non-Retail Packaging - Black: Cell Phones & Accessories to understand what I'm talking about if you're not familiar with this and curious. I'm waiting for my Moto X to arrive and it would be great if this cable works. I love not having to plug in and run two different cables. (my car only has an aux jack and bluetooth support for phone calls only)
