Does anyone know how I can get at the back of the coin holder tray on the 1998 A6 2.8Q? I want to run a wire from the drivers side floorboard up to the back of the holder to hook into an iPhone dock. I am trying to figure out how I can remove the trim to get at it but have been unsuccessful. I need to be able to remove the trim which runs alongside your right leg in the driver's side area.

Any suggestions would be appreciated...
