I can not for the life of me get my unit to eject. Whenever I press the eject button, it gives me 3 choices that are not greyed out on the left, while the right two choices are greyed out. Whenever I select the CD, SD, or the third button, it does not respond at all. What can I do to fix this???? The unit isn't even a year old, as its build date was May 2018.
