I'm thinking about installing a double din dvd/nav unit in my 1990 ls 400. Are they hard to install? i know what i wanna buy, but i know that you loose the use of the subwoofer. what about the changer? do you loose the use if it as well? i noticed that when you buy the wiring harness there are only 2 of the 4 plugs. if you do loose the use of the changer, is there any way you can wire it up to still be able to use it? -Ryan
