Dont know about the 08 model.But if the console is similar to the 03 then Id go with the Kenwood DNX8120.I just installed it and it looks factory,very flush with no gaps or misfits(also double din).Is a pretty pricey unit however,but it includes nav,dvd,radio and bluetooth.It also has 2 usb connections for ipod or flash drive.While I kinda like the Tom Tom nav a little better,its a great system.
have a look-
