I know on some radios they had a screw behind the knobs or on the back of the radio to fine tune the reception.If there was it's funny they wouldn't of mentioned it though.Did they say that alot of people have been complaining of the same problem,and if not tell your salesman you want to take another 350 for a test drive and see if its as poor as yours.At least you'll know if there all junk or yours is defective.Good Luck sr123
When I return to the dealer I will ask about the screws to fine-tune the reception; if if would have helped I would have thought they would do it. Reading the posts now (almost 6 months after my original post) I see that there are a number of complaints like mine about the radio reception. I have tested the reception in other 2006 GS models and the reception is also poor. Lexus gave me a $250 credit to spend, but I really would just like my radio to work. I don't have tinted windows and the dealer checked all the connections from the real window to the radio. My conclusion is that their radios are simply junk.
