Good Morning!
We have our Sirius S50 plugged directly into the aux input next to the cigarette lighter in the center console of our '06 IS250.
There is a constant "whining" feedback sound that increases and decreases in volume and pitch with the engine's rpm's.
Obviously due to the antenna, the FM broadcast option sounds terrible, so is there a fix for this noise? It's driving me craazy!
Thanks!

There is a fix for this. A TSIB (Technical Service Info Bulletin) was provided by Lexus to address this issue.

Click on the link and print out the TSIB. Go to your Lexus dealer and get it fixed for free :

Good luck, and Welcome to the Club!!!

Thanks PhillipMSPT, That whining reminded me of when I had to use a noise filter in a custom job back in highschool. The ground wire would produce the wine with the increased rev of the alternator. I am going to take mine in for this.

Just got the TSIB done yesterday and the sound is totally clean

SUCH and old thread haha, but will this TSIB still work?

The TSIB fix would work, but since the car is no longer under warranty, it wouldn't be free.
