My RX 330 does the same thing. Here is what has helped. Only use one cd at a time instead of all 6. Also, if you are parked on an incline or the car is not on a flat surface when you turn it on, the CD's will eject. Sometimes if there are 2 cds in and the radio has been playing for a while, you can load one in or change between the two. At times, it will not work for weeks and sometimes it works perfect. It is really hit or miss.
