Hi All Thanks for this forum, it is great. I have been installing a COMAND NTG 2.5 in a SLK 171 2005. I bourght the cables from Kufatec (item 37065-1) an the seems to fit ok.

When you say 'upgrading', what are you looking to upgrade - maps, firmware etc? I had my maps updated by Comandonline and they said if the unit had an earlier firmware version then it was a dealer job to update it, if it was as simple as installing a download then i am sure Comand could have done it.
The good part is that the NTG 2.5 did work( bourght it from naviandbmwparts. SD slot = ok DVD movie = ok Radio = ok Bluetooth = ok BUT!!! The unit is not starting when the ignition is on( or turn off when stopping the car) The navi is not working. It can se 5 satelites and it can give me the right position af the car but when I am driving the 'dot' is not moving on the map. The map is turning when I turn the car A notherting is that the console display is showing Navi please wait and after some time only shows 4 -( see pictures) Do I need it coded when it already did have the APS 50 in the car? Can anybody help please THANKS.
You do need to have it coded,.but. it sounds like it's not getting the proper CAN signals from the car.
Can you use the steering controls at all? (Volume, change station, etc?). 2.5 requires steering angle, speed, and CAN status to properly function - navigation is the place where it's most obvious that these are not working. I would really be surprised, however, if this is the problem AND the steering controls work - they are obviously CAN as well. Hi Thanks for the quick answer.
No I cannot use the steering controls! It surprised me that the cable set didn’t have any fiber(orange)connections. I have the AMP in the fodtrunck and the amp have the can connection But it is not used in the cableset from Kufatec? I am a bit confused now;o) Connected the lautspeker from the amp to the new cabelset Connected the power to the new cabelset Connected the antenna to the new cabelset But there is not any connection to the canbus? (orange) in the new cabelset Is this a fault? I am a bit confused now;o) Thanks for any help out there.
Hi All Just work on the project today. UK-C200 you were right it was the can bus that was missing. So what did I do? In the foodwhell ware the audio gateway is are there 3 connections se photo. 1) Loudspeaker the big connection on the left 2) The current the connection on the right On the other site of the audio gateway there are 2 connections 1) The antenna connection on the left 2) The CAN bus and 2 light cables The can bus have 4 wire 1) Yellow = Mute 2) Brown = Can High 3) Pink = Can Awake 4) Brown/red = Can Low After connecting the wire to the retrofit cables everything did work. No need for programming and anything else.
It was very hard to find the connection on the audio gateway and as the retrocabel was only with gray cables( it would have been nice if the cable did have the same colors as the MB cable). I tried to PHONE Kufatec I was waiting on the phone for 20 min and when I got through the told me to phone again 1 hour later??? I did that and was connected to a very rude person that told me to.

off. They didn’t provide any service?????? I will never ever buy anything from Kufatec again, I am still in chock. You did great!;-) Just to be technically correct for others - CAN is only two wires, the brown and brown/red. The pink is MOST wakeup, and the yellow is mute - in any event, your wiring sounds correct now!
You can also remove the AGW/AMP (your first picture) as it's not used anymore with the 2.5. These sell for $200-300us used on ebay.
You also no longer use the MOST Fibers (orange optical fibers). I've said it before, if you are doing the 2.5 retrofit, getting cables from Frank is the.only. sane way to do it, and his cables are 100% color matched - not that you need it, as they all plug in correctly!;-).
Pardon a newbie asking, but did I read in a related search that this unit can be added to any 2005 171 as the 2005's had the wiring in place regardless if they came with Nav or not?Answer is yes, if you're referring to the NGT 2.5 COMAND unit. The nav and bluetooth are integrated in the head unit for the later generation telematics.
You will need the proper coding and IIRC the NGT 2.5 unit needs to be a virgin unit. If the 2009 R171 has the Harmon Kardon sound system, then it gets more complicated and more expensive (because of a separate HK amplifier/AGW in the 2005 model).

Hello everyone. I have an slk 280 2006 that had an audio 20 and no phone prep. A company has just installed an ntg 2.5 unit and everything works as it should, except that the telephone controls on the steering wheel are coming up as function unavailable. All other controls work as they should.
The company couldn't explain why this function should be unavailable. ( it works on the unit okay) The unit was star coded and the steering wheel functions 'turned on' via the star computer program. Just wondered if anyone had any ideas on this?
