I've got a carling sized usb power outlet in the hole on the left side of the steering wheel. Haven't got any pics, but the size is perfect. Just wired it up to the accessories circuit so it has power whenever the key is on acc.... the one on the right side just has the led for the immobiliser in it at the moment, but I was considering putting another usb outlet in there... I have used the 2 spots below the right vent for a spot light and light bar switch and all 4 in the centre console around the hand brake for various other stuff...
