ml command faults

[marsie]

I have got a couple of faults with my command in my ML.I have only just got the car and am guessing that the command is a retrofit as its a 1999 model???? but the faults are

1-it keeps saying there is no nav cd in but there is?
2-it says no cd changer but there is?

and another unrelated fault is the heater panel wont illuminate

All suggestions greatfully received:neutral:as i am a newbie to mercedes

Get a CD cleaning disc and let that play to see if it will clean the laser pick up

 

[marsie]

Thanks television,i will give that a try.Just tried a normal cd in the command and it played but really poor quality.Oh and for some reason the heater panel lights now work guess its fixed itself

How do you mean by poor quality

 

[marsie]

really crackly with loads of background noise?

 

[television]

If the sound is breaking up, it could be miss tracking, then still the pick up head, I hope that a clean fixes it.

If the FM is ok that that really confirms it for 80% of the faults

the radio is fine on all stations.Another fault is the nav disc is difficult to eject but the audio cd ejects fine??.Also the tv and phone wont work(dont know if they should?)

The TV was not an option on the ML, though you could fit an after market digi box if you wanted to. the car would also need to be pre wired for the phone to work, is there a phone in the car

 

[marsie]

ok thanks, thats cleared that up,dont think its wired for a phone because the previous owner has fitted a parrot bluetooth kit.Just got to find my cd head cleaner now to try tomorow.Then got to suss why the autochanger wont work

As these things are always live on the wake up circuit, you could pull the Comand fuse for 5 mins and see if the comand finds the changer

 

[marsie]

where does the command fuse live and will i need a code?

Cant answer that of hand, but Comand's are not coded.

You should have a fuse chart in with the tools, or tucked in one of the fuse boxes.

When it says No CD it normally means that the pick up is dirty, CD not fitted could be a fiber optic lead maybe not plugged in

 

[marsie]

thanks for all your help,will try pulling the unit and checking all leads are fitted because the changer wont even eject the magazine so i am guesssing its lost its feed somewhere?

 

[television]

Does the CD changer make any clicking noises when you first turn it on

 

[marsie]

cant hear anything?

 

[television]

I wonder if when the phone was taken out they have left the ring open, that would make sense

 

[marsie]

will do some in depth investigation tomorow and hopefully get to the bottom of some of the faults??

[television]

Yes if the car had a phone then they may have left the fiber optic cables unplugged, they are bright orange,if this is the case then you need a joiner to complete the circuit

 

[marsie]

havnt had chance to take the command unit out yet but tried yiour suggestion of pulling the fuse for 15 mins.The command said searching for autochanger but still came up with no changer.Does the changer get its power from the command or is it fed seperately cos mine wont even eject the magazine

There are often 2 fuses,, I still think that the fiber optic ring has not been plugged together
