Selling COMMAND, installing 2.5
I realize everything is integrated into the COMAND now (bluetooth, NAV, HD, SD slot) but what additional functionalities does the 2.5 COMAND provide? Just trying to understand, cheers.
@ gmatj: yes that TV tuner should work...pin layout docs can be printed out by your dealership...you will loose TV and DVD in motion unless you use an aftermarket module for that.
greetingz,
I tried to hook up the new Kombi Tuner (A221 820 4889) on my NTG1 system (MY2007/ E200K) to replace my analogue tuner (A211 820 14 97) and what happened is that it played TV with very very good quality but all the lights in my dashboard were flashing like a christmas tree) So I put back the old Analogue Tuner .
All this was performed at a very reputable MB Dealer. And they did not have a clue !
Any idea what maybe wrong ??
Thanks in advance
Rgds

P.S. I am so very reluctant to go on to the NTG2.5 (although I have the unit + all the harnesses needed from Kabeldavico in Germany)

Aside from the DIY gurus on this site that have competed this task successfully is anyone else offering to do these conversions?
I've been around here for a while, just reading though.
I want to upgrade my W211 2008 from Audio 20 CD to NTG 2.5, I don't have HK and telephone. What should I choose for my upgrade, BD0880 or BZ9880 with a DVD changer? I read all post in this topic and cannot find the answer. Plus, what do i need additionally to install the new comand beside the harness from Kabeldavico and the access to SDS?
many tks

I am not sure if the navigation will work here, maybe i just order and have it install altogether. With the right unit and the harness, is the installation simple or need professional service?
many thanks

Installation complexity is pretty relative, you should find members at the thread having done it. Excluding version coding the cluster, the rest should be doable with basic knowledge.
Actually didn't you have Audio 20 CD (single CD drive) head unit, I thought that is not available for the US, are you from somewhere else actually (I had a colleague with the surname Nguyen, originally from Vietnam but worked in the UK, I assume a popular name). You had better check which unit is intended for your market, even if maps were not available today, I'd expect soon.
My version is Audio 20 CD with CDC, 9 Bose speakers and no telephone. I think it is designed for S.E Asia (I'm in Vietnam). On my friend's imported MBZ the navigation does not work either because no map available for VN.
Taking your advice, I will buy the NTG2.5 with all accessories including navigation antenna, hopefully map will be available soon. In the meantime I can conform with the GPS navigation on my PPC.
thanks a lot

I will check if this is my case. I already ordered the BD0880 anyway.
I bought the HK NGT amp for a w211-----try MBenzNL for the part----see your dealer for the connectors (you will need serveral), unless that company makes a harness to convert to the correct HK harnesses.....
Also know that the NGT system used 2 seperate amps, one for the center/front/rear/surround and another for the sub.
Good luck with the install!!

I am still not sure if my W211 is same your case because my wife drives the car. I will check it soon. I already ordered the BD0880 the version with internal DVD changer. I also ordered the adapter set from Frank at KabelDavico for W211 with Audio 20 CD to upgrade to comand 2009 NTG2.5. In your case, what additional connectors/parts you need to install the new comand?
Many thanks

Looks nice
One question : On a W211 MY2007 originally with Audio20 NTG2.5 was retrofited this morning (using the Kabeldaviko cables)
Everything worked fine except that there is no sound coming out.
I suspect it could be the COMAND module was set-up for a car having a Harman Kardon kit, wich is not the case on my car.
The MB dealer tells me it is impossible to do anything.
Any idea what can be the problem and how it can be rectified ?? (Any ideas more than welcome !!!)
Thanks in advance

One option would be to put the unit to a new car and program the MOST ring as it should be on your car. SDS should be able to reach the Comand then.

It do not think it has to do with SDS - NTG2.5 should work even without SDS coding. - A few guys who have done the upgrade have all said that it work Plug nPlay !!
I have read in some other threads something about making the Antenna active but I thought the Audio20CD antenna was active - (and if not how are you suppose to make it active. - Also even if not active you should be able to listen something - shouldn't you ?

I thought you have no sound, not only no sound from the radio. If you don't get any sound from a CD, the radio antenna would not make a difference.
I don't know what you mean by making the antenna active. You have to feed the antenna activation signal, is that what you mean? But don't you get that from the new head unit equally from the older one.

and thanks for taking the time to look into the post.
Let me give you a clearer picture
The retrofit of NTG2.5 (A211 870 50 94-Single DVD) was done to a W211, MY2007, with Audio20CD.(with A set of cables from Kabeldaviko , http://www.kabeldaviko.de/r171-w211-adapterset_ntg.html )
Everything was left at a Main MB dealer who reported on the phone that he fitted all Ok and everything was working Ok but no sound (only noise) !! By the time I got there to pick up the car and see what is happening he had put back the Audio20CD - When I asked what did he mean by no sound - he said again that he could not get any radio stations (I just hate to think that probably did not connect the black antenna fakra to the NTG unit beacause colours did not fit --antenna on the NTG2.5 is a twin white fakra !!).
When I asked if the sound was on from other sources such us CD and/or Navigation he said yes (but I am not sure he had really tried .
So I decided instead of killing the b......... to take the car and come home and try to examine all possible chances of that happening and go on Monday again to start all over again !!
and stakes that I kill him on Monday are quite high ! - so please give us your ideas ...

It seems MB mechanics can only connect harnesses of the same colors --and this for 58 Euros+VAT per hour
So again any ideas you may have are more than welcome
Thanks again

The antenna amp will not have power after removing an AGW. You will have to wire it to a circuit 15 power lead. Also did you not get the correct antenna wire? It is avail new from dealer (from antenna amp to COMAND).
Also "no sound" is different from "static"--------esp when trying to diag a car over the internet......

Antenna cable that was going to Audio20CD now with Antennenadapter 171-717 (double fakra to fakra) goes into the NTG2.5
Also quadlock adapter connects to harness Quadlock-Adapter 171-716
which connects to quadlock on NTG2,5.
Can you make somthing out of this ??
P.S. the picture shows the wiring harness kit used

It should be easy to diagnose the FM antenna by connecting a temporary antenna directly to the new head unit.
