I am new to the group so forgive me if these questions have been asked. I have search but could not find what I was looking form I have just purchased a 99 es300 and had questions regarding the stereo. How can I tell if I have the optional Nakamichi unit? I have a 6 CD changer in the glove box, but there is nothing indicating what type of unit I have. Any help would be appreciated. Also, I am putting on new tires shortly and was curious as to the largest size I could out on the stock wheels. I would like to go with 50 series but wasn;t sure if they would rub or not. Again, thanks for any information that might help.
