Have alpine chm s620 ,error message say no disc magazine is loade

You may download a copy of the manual here. The second page describes how to put discs into the magazine and the magazine into the unit.

You can find the manual here: http://www.alpine-electronics.ru/fileadmin/user_upload/manuals/history_products/CHM-S620/OM_CHM-S620_MB.pdf

Go to a magazine store at your local mall. or a book store.

Ok..just happened to me. I'm a tinkerer so it's assumed that everything is out of warranty. The low down and skinny is this. The last disc holder is stuck on the metal changer tab, preventing the magazine to eject. 1. Remove the six screws on the left and right sides. 2. Use a small flathead screwdriver to GENTLY pry off the front Alpine CHM-S620 plastic facia.\ 3. On both left and right sides, collapse and push in the rubber suspension mounts. 4. Carefully remove the vertical/horizontal mount springs. 5. Gently pull off the data cable ribbon. 6. Flip over the changer unit. Use a coathanger to gently push the cartridge back into magazine. **You may damage the cd and last holder. Small price to pay to get things back to working order though. You may also have to wiggle the last cd holder to get it over the metal lip. 7. Reassemble in reverse order. 8. Change out that last cd cartridge so it doesn't jam again. Good luck.

Check out www.crutchfield.com . you can cross-reference your vehicle model and they will show you what is available for your vehicle. They carry a large inventory and I have purchased from them several times.

There will be a silver or white tag on the back with the model and serial # on it. If it's not there, just visit a car audio shop that sells Alpine, any experienced installer with one look can tell you what it is. Hope this helps

Usually an Alpine unit.  Try ebay.

if you open the cage on the unit, you can pop the tray back out of the mechanism by VERY GENTLY turning the load gear on the carriage, be sure to not slip any gears on the drive or the changer will be out of sync and will be garbage unless you have it serviced by an Alpine service center. you are best to turn the 1st. gear beyond the carriage motor, or you can apply power to the motor (which I don't advise) to let the motor eject the tray. if you do choose the power method, be 100% sure of the polarity first otherwise you will damage the carriage and drive gears. the motor has a brass gear and the rest are nylon gears, the brass gear will very easily shred a nylon gear. want to be extra careful? manually turn the load motor gear itself, it will take alot longer to do, but will be the safest. I've been inside these machines quite a bit, hope I was able to help.

I've got the same problem with my Alpine changer. It seems like a widespread problem, but known cause or solutions.

Dont know Steve, i am no fundi with electronics but could it be that your system is set up for the steering remote, or perhaps not activating because of a wiring or button contact issue ?
Hope you get it sorted out.
