Thanks,
I understood that the Lexus dealer can install a hard wired plug to connect directly into the audio unit??
Do you know anything about that?
I have a GS300 2006, and just installed an adapter...works great using the touch screen on your navigation.
look up vaistech.com
lexus or car stereo places will sell and install for you. the adapter is about $300 and installation is $200 - 300 depending where you go.
if you search the forums, you will find instructions how to do it your self.
I installed myself, not hard at all!
took me 30min to do....worth it!
