u guys think factory pioneer Cd changer off from a 98 GS400 w/Nak will fit on a 99 RX300 with premium stereo. Because my DAD's CD changer not working, and Lexus charges around 600 for a new one so im not gonna even bother.

i tried it , and the big plug fit,it's plays the CDs but theres no sound. And also on the Cd changer off from my GS thers another blue slot for another plug that on the RX doesnt have. Anyone knows what that plug for, and think that could be the reason why thers no sound
