Hey! So i have a Lexus is 220d 2009. I have the stock audio system. The one without touch screen. When i was looking for Lexus for sale, there was not even one car with the touch screen. Could someone with any experience with Lexus audiosystems tell me if i can or cannot rip the old system out and replace it with the touch screen unit. And also please tell me if i need adapters, re wiring etc... Thank you - Ozzo
