I called around and one of the Verizon Stores in my area actually had them in stock. I picked one up and it's pretty decent quality, it slides in from the top and plugs into the usb so you can hook up power directly to the dock. Not my favorite style, but much better than a universal.
I am really getting frustrated with my inability to customize the car dock screen. I want to stream Pandora while hooked up to the car dock but can not find any way to put Pandora on any of the car dock screens. It's driving me crazy.
