LuvMyLS460

Add me to the list of folks that find the NAV lockout on our LS460's extremely irritating. What next? Locking out changing a temperature setting, turning on or off the A/C, changing from XM to a SAT setting, or GASP! - opening or closing a window? I understand Lexus wanting a CYA, but for Heaven's sake give the buyers the option of assuming any risk or responsibility if I cause mass destruction while actually wanting to use a feature I paid for.
