I received a doa purple manual also, the usb connector was damaged and wouldn't make reliable connection. They asked me to send it in to them on my last order. I received another purple that I'm using right now that has no problems, as well as a black that I have in the car. Another gun metal one shipped today.
The bag that the pass
through came in showed no damage, so I have to assume that the cable was bad at the factory. Some failures happen with any manufacturing. So not unusual, and the gang at V4L will make it good, they are the best.
