Has anyone added Bluetooth (aftermarket) to their Lexus? I have an IS250 (non NAV). I came across a website for Melbourne Lexus and they offer a Bluetooth package that can be installed. Has anyone used this? If so, can you give me any feedback on the product and its installation? Thanks Norman p.s. Here is the link. http://www.citylexus.com.au/default.cfm?section=6.2
