ok, I have an Eclipse 5331 esn high power stereo and i just installed it in my truck because it was my dads old one and he just gave it to me so i would have a cd player. I installed it right and everything but i push the power button and put a cd in and it pushes it back out and the screen says "sec". so if anyone knows what this is and how to fix it then i would appreciate it a whole lot.....thanks
eclipse comes with ESN(eclipse security network" , when your dad installed the cd player he activated the security by inserting a password CD. it could be any Cd of his choice at the time. When you unhook an eclipse cd player and reattach it the security feature comes on. the only way around it is to get a master bypass from eclipse of find the password cd
