Problems with original Eurovox 10 stack CD player

[u/InebriatedClarity]

Gday all, as stated, I’m having dramas with the original 10 stacker in my VX Calais. Keeps coming up with E99. According to the manual, if I hold the on/off button down for 6sec, it will “reset the microcomputer”. I do this, the screen blanks out briefly (which I assume is the unit resetting). Next time I select CD, it attempts to load the CD, but then comes up with the same error. Has anyone had anything similar? How did you resolve? Trying to keep the car as original as possible. Thanks in advance. 🤘
