Installing additional power jacks (lighter/usb)
 

Picked up a 09 S8 I would like any ideas/suggestions from anyone who installed additional power sources to power up cell phones etc. USB would be nice, seems like it's the norm in the newer cars. I don't like plugging the USB adapter in the lighter having all the wires hanging out. Taking all suggestions even on location for a clean look. I was considering under the armrest. Are there any kits available?
