These old MB CD changers have been driving me NUTS!! I have been trying to fix this sucker for literally 9 months since i got my car, and after many temporary fixes i FINALLY found the perfect solution.
Tools & Supplies:
- Black electrical tape
- phillips screw driver
- corn pads (optional)
- Memorex (or any other brand) CD Lens cleaner
Step one (picture 1):
Pull trunk carpet up and locate the two mounts w/ the phillips screws in them. Unscrew the two screws and place them in a safe location where they will not get lost.
Step two (pic 2):
apply corn pads over screw holes, feel free to double or triple stack.
Step three (pics 3 & 4 & 5 ):
Pull up the entire housing and look at the wies below. You can see there is one tiny plug and one large plug. The tiny plug works great, it is the power cable. The big plug is the culprit we all love to hate. It is the very reason why thousands of MB owners have had to replace their stereos & CD changers MULTIPLE times. It is the worse designed plug I have ever seen. It hangs in the slot all loosey goosey and is why we get the dreaded "Magazine Empty" & "NO CD Changer" errors. Pull both plugs out.
Step four, optional (pics 6 & 7):
This is to adjust the orentation of the CD player from horizontal to vertical or vice versa. Take the large steel casing mount off the CD changer via the 4 phillips screws. Then take off the sticker covering the holes. and just mose the silver spring mount from H to V or anywhere in between (for diagonal mounting). once done reapply sticker.
Step 5 (pic 8) :
apply padding of some kind to the rubber bottom mounts. I used the fluffy velcro side but you can use something else if you like.
Step 6 (pics 9):
This is by far the most crucial step. The big plug is so poorly design that its always shifting about. So what you have to do is essentially create a "sling" out of black electrical tape to help need the plug "plugged in" all the way so the plug is in as far as it will go (normally there is literally 1/8th - 1/4 inch play, thats how loose it gets). I chose black electrical tape for a few reasons: one its very cheap. Two its black so it won't stand out. three, its very sticky and will last a very long time even in hot conditions. Four, it has elastic properties so it creates the proper amount of tension for the plug.
Step 7 (pic 10):
Use a CD lens cleaner like this Memorex one in order to clean the lens.
Now my CD player is bulletproof and never skips and never lags or takes a while for the song to start playing.
To Sum up:
- Black Electrica tape = $2
- CD lens cleaner ~ $10
- Tools = you already own them
- knowing that you fixed your CD changer for under $15 while most other MB guys had to replace their headunit & CD Changer multiple times and still having figured out the problem... = $ PRICELESS
As a side note:
-If you are having the "Empty Magazine" or "NO CD CHANGER" warning its probably the big plug (aka the bitch plug) itself.
-If your CD changer plays fine on certain sections of the CD but not on others (Mine would always get stuck on song 8), then its probably a dirty CD lens
This process should fix pretty much any issues you are having with your CD player. Anyways... ENJOY!
