Changer won't acknowledge discs

If your Bose 2020 radio is not connecting to your 2016 multi-CD changer and is not recognizing discs 2, 3, or 4, there are a few things you can try to troubleshoot the issue:
1. Check the connections: Make sure that the multi-CD changer is properly connected to the Bose 2020 radio. Check the connections for any loose or disconnected cables.
2. Check the disc format: Make sure that the discs you are trying to play are in a format that is compatible with the CD changer. Some CD changers may not be able to read certain formats or may have trouble reading scratched or damaged discs.
3. Clean the discs: Try cleaning the discs to remove any dust, dirt, or fingerprints. Use a soft, lint-free cloth and wipe from the center of the disc to the outer edge.
4. Clean the CD changer: Dust and debris can build up inside the CD changer, causing it to have trouble reading discs. Try using a CD cleaning disc or a can of compressed air to remove any dust or debris that may be inside the CD changer.
5. Reset the system: Try resetting the Bose 2020 radio and the CD changer. Unplug the power cords from both devices, wait a few minutes, and then plug them back in.
If none of these solutions work, there may be a problem with the CD changer or the radio. You may need to contact Bose customer support for further assistance or take the devices to a qualified technician for repair.

I had a similar problem when I forst got my CD changer, and I had put the CDs in the cartridge upside down. You may want to try it at lease...You may, if it is an old changer, get a can of compressed air and blow it out, it may be dusty inside....Just some thoughts...

There is a manual eject slot on the side of the CD changer. You will need a small flat head screwdriver or a pry tool to insert into the slot.

Label of the disc faces to your right and make sure the number on the display matches the slot you loaded.

sounds like the tray inside was misaligned when the cd went in. and it probally sent the disc into a occupied slot. you will have to remove radio and disassemble to repair. also try just unpluging radio and plug back in. sometimes it resets the radio and will start ejecting the cds

It's not a fuse. More than likely it tried to load 2 discs into the same slot and jammed. That's one of the most common problems with shangers. If you pull the unit out of the vehicle and open the top you will see how it's jammed. Lightly move the CD towards the tray side, not into the cartridge, then plug the unit back in. It will reset itself and then you can eject the cartridge. Then inspect the cartridge for warps or cracks. You may want to replace the cartridge, they do wear out. Also, a good habit is to run a Laser lens cleaner thru the unit itself 3 or 4 times a year to keep the lens clean. It's really the only maintanance you can do. Hope this helps

Clean the unit if possible. does the cartridge eject? if so, load it with a cd player cleaner, preferrably one that uses a cleaning solution. put it in tray slot 1. load and wait. try this a few times then try a good disc, one that is not scratched up. changers are hard on cd's. If it's still not working, below the cartridge slot there should be an inverted dimple that you can press with a ball point pen. This is a reset. It should have this button, I just can't remember the exact location if it's not right there. Hope this helps. If you have a spare cartridge try that as well, as they warp.

Check the changer and see if cds are inserted correctly or if 2 cds are in one slot.

The laser is dirty (happens alot in a car, especially the trunk) or damaged. a repair shop is your best bet.

hi make sure that you cart is inserted all the way in, push the eject button why hitting the mag with the handle of ascrew driver. this may dislodge the jammed arm/lever. otherwise its down to your repair agent.
