I purchased my V Command from Advanced Navigation. The width and length of the V Com unit is about the size of a CD case and approximately 2″ thick. Included was a microphone, GPS antenna and cigarette lighter adapter. It also comes with a zippered leather carrying case. Set up is simple, you just place the GPS antenna on the dash of your vehicle, clip the microphone on the sunvisor and plug it into the cigarette lighter adapter. The adapter has an on/off switch with a green LED light informing you that the unit is on. Within a few minutes it received a GPS signal.
