I performed the DVD / Bluetooth Phone Bypass earlier today on my 10 day old 2006 GS300 AWD.
I honestly went inside to just take a look around. Once I had the Nav unit pulled out and I saw how easy it was, I couldn't resist.
I grabbed the nippers, some solderless connectors, heat shrink tubing and went to work. I ran a ground wire to the lower left 10mm mounting bolt with a ring connector, tightened it all up and took a deep breath while stepping on the brake pedal and pressing the start button.
I was greeted by the Lexus welcome screen and then the screen display the attached image telling me that I had completed a sucessful mod!
I live in the Long Island area and would be happy to offer advice on performing this easy mod. I pulled out of the driveway, and dialed my house from the touchscreen while driving! Of course, my wife didn't quite understand why I was so happy. So I hung up and watched Batman Begins on DVD.
