"The SAM module must be removed by loosening four torx screws, then pull the entire SAM unit up, then locate a large 14-pin pink connector, remove and disconnect the red/blue line placed in cavity 6, replace with retrofit harness wire, assemble in reverse order."

I'm talking about the magenta connector that can be seen on the pic.

If I remember correctly it is not used, that is the feed line to the ashtray 12V socket wich is already installed.

I have currently installed an Audio 20 system on my car and I would like to upgrade Comand NTG4. Among the various components used for retrofitting is A2045409706 cable. What I no understand is whether this cable is also used for power display, or is it always necessary to make the modify on the original connector' s car, or use the appropriate adapter cable selling on Kabel Daviko site. Thanks for the replies (I need). Excuse me for bad english. Gerolamo Italy

I managed to install the comand, thanks vic.

Is it normal that the navigation does not remember your location after you shut it down? It uses a location that you have shut it down at some point and then sometimes it resets itself to a new location...

Also every time you open a door the screen goes black and restarts?

is there anyway to open 7" motorized monitor without connecting to head unit power source?

i have received one and would like to examine display?

thanks

vic viper

There is a small stainless tab in a recess on the upper side of the unit, just behind the folding lid, slide it and you can open the mechanism by hand.

Holly crap, good job!

Ok just to clarify:

new comand unit and monitor need to be linked using a data cable and a power cable.

From what i read the original data cable (A2045405606) between screen and headunit is replaced by (A2045405706)?

Power cable then must either be rewired or use harness from original part list on page 1?

Am i missing something? what is the kabeldaviko display adapter some users mention?

thanks so much

Alright

Install complete. Everything works and looks great.

I do have one issue.

Motorized Monitor opens when car is unlocked, when any door is opened, and when a click sound is heard from engine bay. This is all with no key inserted and engine off.

Car will be off and locked, and screen will open and close randomly and non stop at some interval.

When engine is off the "close screen button" on the vents will infact close the screen. When engine is on and radio is playing the button will not close the screen.

When I turn engine off, the screen will close and then immediately reopen.

Is this a wiring issue or is it a defective screen?

I replaced cavity 6 of pink harness in SAM with new retro red/blue wire. I also plugged in 2 white/black cables to CAN strip, and grounded with brown wire. The retro cable bunch came with one magenta ended wire that is not used I believe. Removing the black/white cables from the CAN strip will stop screen motor.

Headunit engineering mode comes up with 3 errors: "wrong most ring", "lost com with disp-c", "lost com with disp-ctl"??

I appreciate any feedback or input
Thanks much

hellasmania219

any input from forum?

there are mentions of a grounding issue?

i grounded harness brown cable with the rest in the drivers foot well. is there a trick to grounding properly. i want to finish up project but am stuck.

thanks much

Hi, I have a Mercedes C180 (2008) and want to buy the multimedia DVD 40 HDD, This will fit my car? The instalation its with all the original cable from the car or i have to buy additional accesories for the DVD to work? I will apreciate all your help!

I think it's a problem with incorrect MOST programming. I had a similar problem (Comand restarted when I opened the door).

After setting MOST correctly with Xentry everything was fine.

hellasmania219

thanks much,

i think you may be right. The error code i get is "Wrong Most Ring", and when i unplug power to headunit, the monitor stops acting up.

I got my headunit local for cheap in like new condition. Can these things come up stolen..AHHH?? i hope dealer can do the reprogramming for me.

thanks again

I have a C300 2010 and didn't purchase the COMAND or UMI. I called a dealership and they said it's nearly impossible to have it installed since I'm not prewired, they would have to fix the antena, etc. Is that true?

There is no single wire that needs to exist in the car. The kit comes with a GPS antenna that is supposed to be installed to the instrument cluster space. Would you like to have the WIS instructions? Perhaps you should give those to your dealer if he is not able to use the tools at their shop to find this info.

hellasmania219

just to mention. the blower fan has 2 screws that go into the 2 existing holes under dash. the screws and holes did not line up. i could in no fashion get them to line up. i used one of the screws and devised another method to fasten the fan in place.

just a heads up or maybe some feedback?

Vic,

I'm not much of a Comand guy, but my dad surprised me with a purchase of one on ebay. so here I am reading and learning about retrofitting one into my 204.

there's few things I'm confused about.

1. the ECE I got has part # of A204 900 59 03 (does it have to do with the park-tronic button that's on there?) would it work with my US spec 2008?

2. I'm reading that you would need a new vent? A204 870 28 51 or is this a switch behind the vent? since in your parts list with picture it showed a vent.

3. right now I have the GPS antenna (aftermarket apparently came with the purchase), A2048204697 monitor, A2045405706 Screen wiring harness (the cable between screen and the main unit) and the A2049005903 head unit.

if I'm understanding correctly I will need the below parts:


A2045409706 APS wiring harness (the APS harness is the retrofit harness, correct?)
A2119840429 Bolt for fan x2
A2048321245 Air duct
A2048320645 Air duct
A2048320545 Air duct
A2048321045 Air duct
A2048300508 Axial fan

however I'm also confused if I would need these:

A2048702851 Central air nozzle screen switch
A20483041549116 (black) Central air nozzle
A0225457426 Clutch for antenna cable
A2118200088 Antenna adapter cable

if i dont have a changer do i need this part?? A2048703596 Operating unit with DVD changer (ECE)

rssid

Need a bit of help I've got most of the parts required for the comand retrofit but only lack the axial fan , ducting and wiring for a RHD veh. Can anyone help ?

As far as I know
A2048300508 Axial fan (No diff in LHD or RHD veh i'm assuming ?)

From LHD Veh list ... I dont think these will fit the RHD veh ?
A2119840429 Bolt for fan x2 (Most prob will be the same)
A2048321245 Air duct -- from LHD list will it fit RHD ?
A2048320645 Air duct -- from LHD list will it fit RHD ?
A2048320545 Air duct -- from LHD list will it fit RHD ?
A2048321045 Air duct -- from LHD list will it fit RHD ?
A2045409706 APS wiring harness (Most prob the same)

I just want to swap the 5" to 7" screen for my audio 20 system. What do i have to buy and do?
VIC you said the screen look strange. What do you mean? Thanks!

lovew204

I bought the 7" display unit on eBay. Please help me to connect it with Audio 20 headunit... Thank you!

theonidis

You can't connect it to audio 20, you can connect it only to comand unit
