Does anyone know when you order the Nucleus NC-X2iLAN from Logjam if it comes with directions for installation? I have read that people say it is right behind the glovebox. Does anyone have any specific information on accessing the XM Module? I have a 2007 with factory NAV w/ XM Radio. I'm not very good at taking things apart, but I would like to try and install this. Any information would be greatly appreciated. Thanks.
