First, I would like to say I am the proud owner of a Brand spankin' new 2007 Rx 400H. I purchased this silver with black interior beauty from Smithtown Lexus and had a grest experience there. They were very nice to deal with....very upfront and professional. I have had the car for about 2 weeks now and have to say coming from an infiniti fx 35 I am very pleased with my new lexus. Plenty of power and rides MUCH smoother. I purchased my new lexus with the nav and premium pkg as this was the way it was in transit from Japan. I can't believe that it didn't come with sat radio!! And, I was not paying 800 to them to install it. So, I searched ebay and found the factory install kit for $250 from some dealer in arizona. Let me first start with saying this is a VERY difficult installation and not for the faint of heart. ALL of the rear seats, cargo trim, and rear bumper have to be removed to install this kit. Total time was about 4 hrs and I am very technically inclined. There are a few places on the net to download the instructions if you are curious what it intails. If anyone has any questions about this feel free to e-mail me!
