I too just picked up my RX350. I'd like to install the XM radio as the dealer was asking an outlandish amount to do it. I looked thru the PDF directions for doing so from Sewell and they seem workable. But I'd be much more comfortable taking it on if we could hear from some owners who've already done it. At a different forum I've read where others found it easy to do but it was on a different Lexus model. Taking the various panels and covers off in the passenger compartment is scary as I have visions of not getting them back together properly. Anyone else done this?
