thanks for the replies
I removed the unit from the trunk. I also discovered that there is a popout window on the side of the unit that exposes some gears. If you turn those gears with your finger the cartridge will lift. If I have more problems I will most likely send the unit off for repair.
The most common problem I have with the unit is that some CDs will not load. This seems to have some relationship to the label because it does not seem to matter whether the CD was CD-R or was store bought.
Someday I would like to buy an adaptor cable that will enable using a MP3 player and forget the CD's altogether.
