I have a 2006 F-150 Supercab Lariat with the 5.4L. First, let me say that I had read many rave reviews of Travis' www.kcautosoaund.com on www.F150online.com prior to my purchase. Many experienced members there said the CA680 is the optimal product for the F-150, and that KCautosound is the ideal place to find the right price with service that makes the install easy. That said, I ordered the CA680 with prewire, and the PATS bypass module. They shipped it the same day I placed the order. After my personal product purchase/install, I must say the guys on F150online.com were right on the money. Sure, I could have found it cheaper, but he made it so very simple to install. He was right there for me on a few questions I had via telephone (on a weekend I might add), and I am very happy I chose kcautosound. The install and programming with his excellent prewire and color illustrated instruction set went very smoothly. He saved me time and money. I feel great about getting top notch service, a great alarm system, and the personal satisfaction that I did it by myself in just an afternoon.
