i just installed a usa spec ipod integration unit in my 2001 RX300. used CAS-TLC cable to basically eliminate the cd changer and use my iphone. everything worked fine until i put everything back together. i can no longer change "disc" modes from the radio and have the freedom of direct mode and choosing the music i want to listen to. has anyone had a similar problem with this? please help non nav premium sound using iPhone4
