Enabling Nav in Cluster Display

[Alfie]

I'm looking forward to having this on my car, I just need the steering wheel and some cables etc now, I already have the instrument cluster

Taking a saw to the instrument cluster will be the nail-biting bit, I suppose I could get it all wired up and activated by the stealership and then remove the cluster again for the cosmetic work (saw the front off and swap with the W202 cluster).

Thats the bravest mod/upgrade I've ever heard of!

I test-fitted the CLK instrument cluster and it goes in fine but sticks out at the top by about 2 inches

W202

W210

W208

Taking a saw to a brand new CLK55 AMG instrument cluster is going to bring a tear to the corner of my eye, I assure you

EDIT:

here is the new cluster:

Gosh, it only took you 2 mins to swop them - and it's nice and warm in your garage!

Think about it! Clock reset to 12:00 every time we plugged a cluster in! Workshop was MBenzNL's in NL.

I thought they were Photoshopped actually! The fuel levels are different. I didn't think they really had been fitted.

The fuel level problem is why the W210 cluster is not used in this situation, it has a reversed feed for the fuel level! W208 and W202 have the same senders.

The malfunction listed on the W210 display is failed glowplugs, the cluster was from an E300TD . The W208 malfunctions listed were ASR/BAS which was true, my brakeswitch was broken at the time.

Okay, update about my Navigation coding.

I went to pick up the car, had to wait 30 minutes despite being told it was ready, only to be told that yes, the Navigation coding has been done (according to Alfie's instructions I printed and gave them) but the CD changer doesn't work as COMAND can no longer see it.

Obviously I refused to take the car away with the CD changer not working seeing that all was well when I arrived and duly the car went back into the workshop to have the changes undone.

According to the service manager, the various car systems are in an logical loop, and by making a change to the instrument display, it could have thrown off the knowledge that the car has a CD changer. He also said that they could not communicate properly with the COMAND as it could not be reached on the diagnostic port.

Consequently, my car is in the same state now as it was when I dropped it off this morning and I'm more than a little annoyed.

How do I...
a) get the display coded so that I have Nav arrows in my display AND a CD changer?
b) get this diagnostic pin thing working so that COMAND can be told there is a CD changer there?

And do I need to do (b) before (a) is possible?

All advice gratefully received as always.

The "logical ring" (which is in fact a physical ring called D2B, which has phone, cd changer, head-unit, voice-recognition, digital-bose-amp on it). However, the cluster is not part of this, and shouldn't have been affected. However, strange things can occur if the COMAND thinks the order of things on the D2B bus is different to what it actually is. (but its never been clear what may be affected)

I imagine their service dept. then decided to go look at the COMAND and couldnt access it because there's nothing connected to the COMAND pin on the diagnostic connector (its probably connected to the RADIO pin under there, unless you moved it)

Read the section in my retrofit document at http://www.mercupgrades.com about the diagnostic connector, its easy to move pins in it

BUT, its worth doing the following. Go into COMAND's hidden diagnostic menu (enter aux input mode (press sys, select aux), the hold down the following 3 keys, MUTE, 1, 3 for about 10 seconds. In the diagnostic menu you will find a menu with a column of numbers for what COMAND is configured to see on the D2B bus, and one for what is there. If they are different, then they do need to be sorted out.

Someone messed up the C1 pin connections. It works regardless when installed correctly.

I think you will find that
a) the optical ring is open
b) wakeup is not connected
c) power from the COMAND to the stacker is not correct.

Hold on, I read the post as saying that the CD changer did work - it stopped working when the dealer enabled the cluster, and started again when they disabled the cluster.

If thats true, unless the dealer was being real dumb and actually disconnected the changer or fiddled with the wiring, then something else is up. (of course the C1 connector, or the fibre loom could be not connected properly!)

And, although it works when connected, (without re-coding comand) there is the odd known case of odd behaviour - normally caused by software bugs in other systems - having VCS after the phone system in the loop (for instance) works most of the time, but not always !!

If rosechap runs that diagnostic which tells you what is on the ring (and publishes the results) we can see exactly what is on the D2B ring, and what the comand thinks is on the ring.

If the Diagnostic cant see it then how is the COMAND going to see it ?

The cables are not as they should be. Ring order is only marginally important. Pehaps we need to define "working".

Hi Miro - I seem to have read what Rosechap has said before in a different way to you, so yes we definetly need to define "working" !

(I'm being detailed with explanation here so it's useful for others)

I think that Star can not see COMAND at all (rather than it can see COMAND but not the CD changer) because its a W210 , and the W210 has the 38 pin diagnostic socket - which has different pins for Radio and for COMAND. As the car was upgraded from radio to comand. From what RoseChap said I do not think that the pin has been moved in the diagnosis socket from pin 33 to 34. Star uses COMAND as a gateway to the D2B bus (and to the CANbus that has the TV on it, known as a KINgateway and a CANgateway in diagnostic terms I think)

Lets start at the basics for Rose Chap to answer then see whether we can sort this out for him between us.

Before you added COMAND
(a) What head unit was there
(b) Was there a CD changer, or an integrated phone (with steering wheel controls), or linguatronic/vcs (voice recognition)
(c) Did it all work

When you added COMAND
(a) Did you move the diagnostic pin from 33 to 34 in the under-bonnet connector
(b) Did the CD player still work
(c) Did the phone (if fitted) still work
(d) When COMAND is turned on initially, do you see the MB Star and then a a screen with the DX logo

Please go into diagnostic mode (select AUX input by pressing SYS key, then selecting AUX). Then hold down the 3 buttons, MUTE, 1, 3 all together until diagnostic mode is entered.
- Now goto the configuration screen, and tell us what is ticked and the numbers in the bottom left
- press RET and goto diagnosis then D2B components
- does the actual column match the config column
- please tell us what is shown on that screen
- press RET and go into error list, pls tell us what is there, then hold down MUTE and 0 together to clear the error list
- press RET twice and go into versions, wind down the screen to D2B and go in there and tell us what is there

Thanks
Richard

I always move the K-line since I know this will happen if I dont.

Morning Richard, thanks for the help so far. I can't get into the COMAND menus at the moment as I'm not with the car, but I'll report back on that later this weekend.

To answer your questions above.

Pre COMAND install...
a) Audio 10 Radio Cassette
b) MB 6 disc CD Changer in the boot, no phone or linguatronic
c) Everything worked perfectly

Post COMAND Install...
a) No I didn't
b) Yes it did
c) n/a (no phone to start with)
d) Yes I do

Yesterday when I drove the car away from the dealers, every was as it was just after I had finished the COMAND install, as in the COMAND works fine, the CD Changer works fine, the aux input for the ipod works fine, but Nav is not enabled in the cluster display.

Thanks muchly

Andy

PS. Forgot to add, my car is a W208, facelift model.

 

[s1gar]

you dont need to move the pin in the diagnostic block. if you have a facelift model the diagnostic connector is under the steering wheel and not under the bonnet. the wire is already there on pin 34 and i think off memory it goes to the a a connector. i know it is definately connected to the comand.

 

[Alfie]

Andy,

Sounds to me like the diagnostic pin needs to be set properly. I didnt have to move mine and mine is a facelifted W208 with NAV enabled by the dealer.

 

[s1gar]

the dealers have obviously had it connected to star via the diagnostic plug and changed something on the comand unit which would indicate the pin is in the right place or like alfie says there is a problem with the pin. i think they have not programed something properly or missed something out ofthe instructions. does it make a difference if they follow the instructions and enable say for example the phone function does it matter if you dont have a phone? i read somewhere that the main thing they have to do is the last line in the instructions that says navigation to preset. maybe they should try it and not enable the things you dont have. this is just a idea.

The best way to determine this (on E class, different on CLK), is to look under the bonnet, open the fuse box cover, and the connector is at the top of that, - big round multipin connector.
[Edit, forgot this bit]On a CLK, the same connector is on the other side, under a plastic round cover with a hex bolt on the top of it (use socket set to undo)[/edit]
(If anyone wants to photo these for me, i'll add them to my Comand retrofit document at www.mercupgrades.com)

I dont know for sure when/if diagnostic connectors moved on the 210 E-class from under the bonnet to the new style OBD-II (EOBD) connector above driver's legs - I'm not convinced that it did. I had a facelift CLK55 (W208) but I think it had the round connector under the bonnet - I can't really recall.
On some US cars, both exists, with the OBD-II connector connecting to a control unit that mapped between the required US OBD-II protocol and whatever the engine controller in the car talked - then as EOBD was introduced in Europe, they switched completely to the OBD connector above the driver's legs

Thinking more about this, I think that the dealer has screwed something up.

Your car is a facelifted W208 so you have all the right connections for the diagnostic plug in place. The odd thing that the dealer did was to somehow manage to 'lose' your cd changer from the COMAND. If I remember correctly the dealer doesnt actually need to touch your comand or its config, just enable NAVIGATION = PRESENT and save.

Try Tony Purslow in Guildford, they enabled mine and I have a CD changer like you.
