I just got my new 400h a few weeks ago. Its a 2006, and the dealer added XM radio to it. The XM radio works well, but I'm not happy with the antenna installation. The installer used the small magnetic antenna that sticks up on the roof. A wire comes out of the antenna, and goes over a few inches across the roof and then goes under a seal for the roof rack. Its not a professional looking installation IMO. I expected to have a nice antenna (shark fin type or othere) with no wires showing. My previous car was a GM product that the dealer added XM radio to, and I got a perfect installation that looked and worked great.
I know that for 2006, XM radio was not a factory option, and that for 2007 it is a factory option. Does anyone here know what the antenna setup looks like in the 2007 cars?

Followup on the antenna--Lexus never did get back to me.
My dealer followed up for me.
News not great IMO. He said that if you buy a 2007 with XM from the factory, the antenna will be the same as what I have and it will be installed fairly similarly with a wire exposed. No clean sharkfin antenna or anything nice like that. He said that this is problably the end of the rx400h design cycle and that it will go thru a redesign, so no nice antenna setup for now. I thought I was buying a Lexus--everything first class----not.
