I'm new to this site as well as a new Lexus owner. I searched around the web and was unable to find the information i need about this topic. I'm trying to find out more information about the process of switching out my OEM radio, standard model, to a OEM navigation unit. I did not want to go aftermarket and was trying to keep everything OEM. I was just wondering thoughts people had on this as well as anyone's past experiences in doing this. Also wondering if this was worth doing, and if not, what suggestions there were for a Navigation style radio.

Thanks In Advance
