the parts girl at your local dealership is right. toyota has an ipod kit for their cars (including lexus), but it's either xm or ipod. vaistech will allow you to retain your factory xm and have the ipod. not to mention the factory ipod kit isn't that good, i have played with both, the factory ipod kit is not as intuitive and flexible. price wise they are about the same and in some cases vaistech is even cheaper
