I just received my car dock from AT&T. Some notes:
- it has a plastic spacer you can insert into the dock or remove if your phone is in a case.
- though a single microUSB cable plugs into the dock, the other end of it is split into full size USB *and* a standard headphone jack, so the dock will output audio as well.
- It does NOT come with a lighter plug! Just the USB cable. The box says "USB power adapter sold separately. Are they kidding?
