My recomendation is for you to replace the factory radio with a aftermarket radio of your choosing. Aftermarket ipod adapters are good but also expensive for your 2001 lexus, for the same money you can get all the latest goodies like bluetooth,ipod,iphone,aux connections and mp3 and radio tuner. I do this al the time for my customers. mejiadon7@aol.com or at you tube @ protinttemplecityca.
