I'd love to cut down the road noise- how do you add sound insulation? I have no doubt that would make a huge difference in the audio system, and it would make those long commutes better to :)

I've read many of the older posts about the audio system in the RX300. I don't have the ML upgraded system or the Navigation system. But I really need better audio... Is it possible to upgrade the existing system with the Mark Levinson system in my 2001? Or should I just go to Tweeters and get new speakers and an amp?

I'd like to add Satellite radio to my 2001 Lexus RX300. Is there anything out there that will integrate into my existing system? I don't want to mount a box on my dash or anything like that. Thanks
