According to the manual, when connecting an iPod to the aux input and using the power tap, noise will be generated. I might suggest looking at Dension USA for their iPod car kits.

Electrical Connection (www.electricalconnection.com) sells a 3.5mm Ground Loop Isolator which I'm experimenting with to resolve the problem. Lexus should really include this in the wiring or make the part available. It is $2 worth of electronics.
