4th Gen TSB's (Attachments)

high pitched squeal through right side speakers

Hi, I have an 08 runner with the base sound system. I've noticed a high pitched almost feedback like noise from the right front tweeter when using the auxilliary jack while the audio device being played (be it cell, ipod, etc i've tried many) is simultaneously charging via the 12v 'cigarette lighter' outlet. any tsb on this or really, any ideas? thanks!

There is a TSB for this. I can't find it at the moment, but it involves installing a modified harness for the Aux jack that has an inline ground loop filter. I had it done on my 08 and it works like a charm! If I find it, I'll post up a link.
 
After replacing my rotors calipers today and previously replacing the rotors and right one 25,000 miles ago I go to wonder if there is a TSB for this? They constantly drag after awhile killing the mileage, pad life, and eventually warp the rotors. Love my 4th gen but new calipers, brakes, and rotors for the third time in 70,000 miles is enough.
 
How do these tsb's work? If im having the moonroof and exhaust issue with mine can i take it in and show them the tsb's and theyll do it?
