stereo on HSV

[HSVMANTA]

hello everybody i am 23 and drive a hsv manta. Very happy with the performance and it is a stocker. I cant wait to tweak it a little. Anyway i was wondering if somebody could help me , the stereo when youpush the cd button to switch to the stacker comes up with a flashing "e-99" any ideas on this one. I will be putting an alarm in the next few days so i guess the installers can fix it ! I guess i was just curious if anyone else had this problem. ps the stereo is eurovox

E 99 Means the micro computer is locke you have to reset the micro computer by pressing and hold the on/off button down for more than 10 seconds this will reset the micro computer see how you go.
