I got a factory radio from a 2002 prelude in my teg, last week while changing disc the radio will block the opening and displays a P-E 1 code on the screen. Does anybody know how I can fix this? FM and AM works but no way for me to insert a CD.

 

You can try and reboot it, disconnect the neg. (-) batt. term. and wait a min. then reconnect, make sure you have the radio code if it's a coded radio. 94
