Hi there i own an old SL 500 from 2003. the car never came with any NAV disks so i bought one on ebay and i was assured that this was the CD that would play for this car
and yet i can't even insert the CD in the car
does anyone have an idea? i used the search but couldn't any answers
thank you much appreciated

You sure there isn't a CD already loaded in it? Try the eject button first. But on a side note, I have all mine and frankly don't waste your money, use your phone.

100% sure there is no CD in there the only CD in it is the one i bought and forced it in but it's no worries i can get it out. my problem is why it's not working. it's not automatically accepting the CD

Okay, got it. There is no CD.

So there is a CD?

Whatever, if it won't draw-in a CD, then likely a switch or sensor in COMAND's disk-handling mechanism is faulty. Use a web search to find an article on basic COMAND repairs. At a minimum you should find instructions for disassembling COMAND, and on your own you may figure out what is wrong.

Years ago I had the opposite problem: COMAND would not eject a disk, and this was resolved by partially disassembling COMAND and cleaning the rollers.

Finally, I have a smart phone with Google Maps, and I also have a Garmin. Yet my personal preference is to use COMAND for navigation. Between the voice prompt and the display in the instrument cluster it does a better job of alerting me of an upcoming turn.

yes
i mean no it's not drawing in my BRAND NEW NAVIGATION DISC that i bought on ebay
can you send a link please?
should i check for a burnt fuse ?

bobterry99

I wouldn't bother to look for a fuse.

I am certain there is guidance on the web that will enable you to solve your problem. But I have no links; so unless someone else has something to offer, I suggest you search on your own. Maybe try "COMAND Repair", "COMAND Troubleshooting", "COMAND Disassembly"...

Stupid question. Will navigation CD work from the CD changer? Or it must be in the head unit?

cadbob

Just the Head Unit.

It sure sounds like a CD is stuck in Head Unit, also make sure someone did not Replicate the EBay CD and actually burn whats supposed to be CD to a DVD and Print label on it. Could be a Bad Disk. Try sliding in regular known music CD.

On my SL it turned out to be a stuck CD in the comand. It would not play either

Check in the slit where you insert the CD if there are 2 white thick plastic tabs that prevents ant CD from being inserted.
Use a thin wire and a flashlight to see in the slit where the CD goes. .

On my SL the CD would not work at all. The comand would not insert or eject any CD at all.
So early this summer i decided to check what was wrong. I used a little wire to hold up the cover/cloth in the slit and used a flashlight so i could see what was in there and there where 2 large white plastic tabs that prevented the CD to be inserted.
There was also 2 thin white plastic tabs there as well and when i pushed the the thin white left plastic tab to the left the CD player ejected the CD but no CD came out

Then i used a thin wire and held the thin white plastic tab that is in the slit to the left and inserted a CD and the CD was inserted but the CD made some really bad noise so i pushed eject to stop the noise
The CD i had inserted came out as soon as i pushed the eject button but to my suprise yeat another CD came out that had been stuck in the comand.
I guess that is why the 2 thick white plastic tabs was in the way for inserting any CD.

This was early this summer and everything works fine on my car now and i have not had any problems with the CD/comand at all :

I bought a new Tele Atlas 2014 Final Update map CD over northern Europe on ebay for just a few dollars and i am very pleased with that map CD
