What we have here is an excellent video walkthrough of a couple of Verizon Galaxy Nexus accessories that should be available in the morning -- the navigation vehicle mount and the spare battery charging kit -- from forums member Aatrek.
Note it's a "Navigation vehicle mount" and not a "Car dock" or anything. It's a hunk of plastic that the phone sits in, that's all. No contact charging, no Bluetooth audio. In other words, it does not bring, as the kids say, the sex. The spare battery charger, on the other hand, chargers a spare battery. No muss, no fuss.
