Okay so a couple questions for you fellas,number one is there a fuse for the CD player itself? If so which fuse is it? I can't seem to find anywhere online. Also is there any way to manually eject the 6 disk cartridge? My CDs won't eject and when I hit the disc button on the player itself it doesn't do anything,I reset the ecu by pulling the fuse and the screen actually let me access the disc option but it said cd1 error3 on it,any ideas guys? Really wanna figure this out
