I just recv'd the car kit for my iPhone and am having issues with the power. I place the phone in the cradle and have to unplug the usb/car charger and replug it for it to power the BT and cradle. Is this normal?? Shouldn't the phone get the charge sync icon as soon as I place it in the cradle? Also the light on the cig plug corresponds with this: it comes on only when I unplug & replug the usb power jack. I can unplug the cig adapter and replace and nothing happens. It has to do with the usb plug....
