Installing CarPlay Myself
Here is a link to the part: https://www.mercedes-benz-shop.ca/en.../p/A2468203800
Would this guide be accurate in installing the CarPlay? http://www.mercedesmedic.com/unlock-activate-mercedes-carplay-android-auto-comand-ntg5s1
Here is an image of where the part is supposed to go to update the system:

Here is the perspective from my CLS400(to the right of the red thingy, is the OBD port):

I know it's an old thread, but by any chances do you still have the MB docs so I could show to my dealership? The first person who helped me said it's not available, it's factory done only.
Thank you in advance!

What the other person said, don't get the part. All it is is a new USB port where port #2 (the CarPlay port) has a tablet like design. That's all there is to it. Waste of $100+. Just tell them to update the COMAND software.
Apple Carplay and Android Auto. Coding required NTG5*1 COMAND Online and (Code 531 WITHOUT Code 14U).
The dealer can get this integration package and code the vehicle for the Carplay (14U) and Android Auto (16U) once the integration
package has been installed.
Part number: A 246 820 38 00
Includes :
1. Multimedia box
2. Charging cable (100 cm), micro USB
3. Charging cable (100 cm), Lightning
I am hoping you might still have the information, almost 2 years later... :-)
I have a 2015 CLS 550 thats currently at the dealership. After a lot of poking and prodding they agreed to do the software updates. They're telling me its not working.
I called the San Antonio MB dealership and they found your record for the install. But it doesnt have any of the details of what the techs actually did.
Do you have any information that might be illuminating? I appreciate it!
Did they have to install any hardware?

Because if they have the cable in the first usb, carplay won’t work. If that doesn’t work, then the dealer I got it done was at Mercedes Benz Surrey, and the service manager’s name was Raul. I would give them a call and let them know you’re from Texas, and the dealers have no clue on how to install it.
I'll have to pass on this generous offer




I’m pretty desperate. I’m trying to have this CarPlay firmware update added to my mother’s CLS with. NTG 5.5 , I have the dealer the service bulletin pdf and they are refusing to install the firmware without also swapping out the hardware in the center armrest.
I’ve seen enough evidence to believe this doesn’t have to be done the way the dealer wants to do it. If anyone is willing to share the dealership and service advisor or manager they dealt with that is still employed with the Mercedes Dealer I will definitely make it worth your while and compensate you for your tip. They have had her car for 4 days or a 1 hour firmware update.
I’m just thinking if they heard it from another MB dealers mouth they would believe them over me and go ahead and install the for firmware and be done.
thanks for info that may help us out.
