Hi guys I have a BA xt 2005 and i want to put the PREMIUM ICC in it. i just want to know if every thing will work??? i hate the look of the stock on but love the look of the colour screens... any help will be great

Well, sometimes they will work as soon as you plug them in and sometimes they won't.
As long as it is a single zone air one you should have no trouble getting everything to work, you need to change over your BCM and also the Remote control Receiver.
If after you have changed it, and the radio won't work, you will need to get it to a Ford dealer to have it interfaced with your car.
