COMAND (CD version) hidden diagnostic menu

[richard]

I finally got around to documenting (some) of the functionality of the hidden service menu on COMAND 2.0, and what some of the values in it mean..

See http://www.mercupgrades.com

I also added a list of the part numbers for manuals for COMAND, and made the COMAND-APS part number document readable on IE6

Hope this is useful to someone :-)

Cheers

Hi Richard,
Brilliant post as usual, thanks.
I have been reluctant to "fiddle" and get into this service menu as I didn't see any instructions on how to get back out! Probably being too cautious but could you confirm how to get back to normal screens?
Thanks/Barry

You just hit RET (a few times if youve gone into the menus)

Cheers
Richard

Help ! I have a C Class (2000) with the Command Travel Pilot DX but I am experiencing problems. Since receiving the new TeleAtlas CD last year (Could be a coincidence) I constantly have had an error “CD Reading Error Please Use another CD” I am not sure if the system has become corrupt and just (!!ha) needs resetting or if there is a problem with the unit. It is an intermittent problem Take the CD out enough times and eventually it will work, very ocassionally I also get a Audio CD reading problem from the CD player –again “not recognised” – but eject the case and it starts working again.
Has anyone come across something similar? Is there a rest functionality to reset the firmware? Or could it be the optical laser reader that has fluff on it and if so how do I clean it – any thoughts greatly appreciated. Cheers Will

Try a CD cleaning disk. It has little cleaning brushes on it

They are quite prone to getting dirt from your hands into COMAND - normally first sign of this is inability to eject the disk properly ..

Richard, brilliant website many thanks. I went to Holland and Steve installed the Comand into my C43 and a few other things, highly reccomended.

Theres a hint in there (in the configuration menu) ...

I wrote a program called 'freediag' (its on freediag.sourceforge.net, for Linux), which along with an interface allows you to plug into the OBD-II port and act as a scantool (read engine fault codes) - and I worked out how to change/alter values on COMAND and change everything, including TV in motion. I was going to publish it, but got worried about the legal liability issues - and wasn't going to spend cash on lawyers fees - rather spend it on adding other stuff to car and writing that up ...

So, its stuck on the back burner for a while. I sent some of it to Peter Leubner (sp?) who published some of it, and worked out more of the TV in motion stuff.

Maybee I should publish it without the TV in motion stuff shown, and then others can infer what the settings are .. with a big big disclaimer on it ..

I was told you dont need to plug anything into the port to access those features as it was just in one fo those hidden menus.

Not on COMAND2.0 - theres some magic sequence on COMAND APS (i.e DVD)

this is the one I got.

Does anyone on here know the magic number sequence?

[richard]

Thats COMAND APS

Apparently you press MUTE, Hang-up and Serv keys - dunno if you do this all together or seperately, probably together

But, Mute+Eject+Middle-Right-Softbutton also does something
