I'm picking up a new 23 ES350 FSport Handling tomorrow and already planning a stereo upgrade for it. After doing a lot of searching I saw the PAC APH-TY02 wiring interface that would make the wiring a whole lot easier however it says it's only good for the 21 and older ES models. Can anyone tell me if Lexus did indeed change the amp on the base sound system for the 22 and 23 MY? Thanks for any help.
