For all those who have noticed the electrical noise issue when running audio through the aux audio input, as of August 10th, 2007 there is officially a TSIB to fix it! Looks like they are putting an in-line filter in to clear that issue up. This fix is for the '06-'07 IS250/IS350, the '07 ES350, and the '07 LS460. It is TSIB #L-AU001-07 NOISE FROM AUXILIARY PORT WITH EXTERNAL DEVICE
