CDR-23 reboots constantly
 

I removed CD changer and radio went to infinity reboot loop. Before disconnecting CD changer, I removed two fuses for Radio and Amplifier. I know that CD changer was activated with PSP2. Is there any way to make the head unit working again without PSP2 programming?

Thanks!

Did you loop back the fiber optic cable? You have to get the piece to tie it back into itself or modify it with the proper connectors for it to work right. CDR-23 will constantly look to receive what it has transmitted.

@Pirate50, thanks, I fix it by undoing CD changer fiber connectors and looping back to the amplifier. There is a lot of ready to use loops available on Amazon, but I choose to do it myself. It was very easy. Now all good.
