You did a great job! I have been trying to figure out a way to integrate a nav system and aux input into my 99 rx300 and it is basically impossible unless you go to the extreme like you did. Do you happen to know the model number of the CD changer that is in the glovebox? I am assuming it is Pioneer. If so, I am hoping this interface adapter might work as an AUX input for MP3s. http://www.crutchfield.com/S-uXCc3HzuMmr/c...asp?i=130CDRB10
