I bought a 2007 Nitro that hasn't a ash tray or lighter in it . Since both my wife & I still smoke , I would like to install them in my Nitro . Can someone here guide me to instructions and a source that will make this possible . I'm not interested in a cup ash tray . Want one that is mounted in dash . I'm assuming they were available & a option when Nitro was first bought . I need instructions as I will be installing them myself .
