I just bought a 2008 Rx350 and read on the ClubLexus forum that “corner tapping” method to bypass the navigation lockout doesn’t work on newer models or new versions of the software. I also read that there is a wire cutting method that works but those instruction were for a 2006 GS. Does anybody know if the wire cutting method works for 2008 Rx350? If so, could you provide the instructions that have been verified on this car? Many thanks!!

I would first spend some time and money reducing the cabin's ambient NOISE level below the typical ~70+ db level before I invest any money in an upscale audio system. Otherwise the only way to really appreciate a good high fidelity system is in a nice quiet garage with the windows up, the engine and HVAC blower off. Are you might have someone design a music/sound content pre-processing system, DSP, to automatically raise the system sound content that would otherwise be below 70 db up above that level. I've never thought about noise reduction but that's a really interesting idea. Can you you point me to any websites that talk about that sort of thing because I don't know anything about it. Same goes for DSP pre-processing system. Could it be hooked up inline with the factory radio? The fact that it integrates with the Navigation screen and radio display below it seems to complicate matters - at least to me. Does anyone know what types of input/output ports are available on the factory audio system?

I plan to but a 2008 RX350 but Mark Levinson Audio is not available in New England. Can I upgrade the amp, speakers and add a subwoofer with aftermarket components from Crutchfield.com or similar type of place? I don’t want rear seat DVD so the $6K for the Mark Levinson audio would be overkill anyway. Even if I spend $1K-$1.5K with aftermarket components I still figure I’m way ahead of the game. Would a Lexus shop manual have details for audio? Where could I buy such a manual? Anybody have any experience upgrading audio components?
