Hey i just noticed this older post and I am interested in doing the same thing I have a 2002 rx300 non nav and want nav/dvd/mp3/xm capabilities, possibly adding just an aftermarket dvd player either single or double din doesnt matter, just looking for advice as to how to go about all of this. I will also be looking to add subs and an amp etc etc and just want to make sure I get it all done the cleanest/nicest way possible, any information would be great, and/or if you have any products available, like i said I amd pretty open to whatever. thanks
