I have a Mercedes w212 2014 with a Comand system NTG 4.5.
But(!!) The problem is that the system in my car does not have an auxiliary input.
The only way to connect auxiliary audio is via bluetooth or I can connect a USB memory with mp3 files.
The USB port is located between the two front seats, in the box between the seats.
Bluetooth works but it has some downsides that analog input does not have.
I have an Android unit that I really like to connect via an analog interface, to avoid latency (and other problems with BT).
The only port I have in the car is a USB port in the storage department between the front seats. I can plug in a USB memory with e.g. mp3 files. But I can not stream audio to the NTG unit.
Where can I find something so I can "upgrade" to the MMI interface that was commonly mounted in the glove box in many w212?
What do I need for parts?
How shall I connect it to the NTG 4.5 (or is it a 4.7?)
I can buy MMI AMI USB-adapter cables for Mercedes Media Interface. But I can't connect it in my car. My car is not equipped the media interface. How can I retrofit my car so that it gets a Mercedes MMI AMI interface?
What can I do?
If I need som Mercedes original parts, what is the part no for the stuff I need?

Reason: Missed som info
My facelift E350, like yours, is fitted with two USB ports in the console between the seats. It works wonderfully to play music using USB sticks. You don't need "retrofit" cabling to duplicate this technology which works great as is. Search around and you will find that some have also connected external HD disks using these ports as well.
In addition, you also have an SD card slot on the center stack, just to the lower left of the Comand system "ON" button. I currently play 64GB of music and playlists using this interface, too. No need for BT at all, when these direct access alternatives are available.
In short, there is no reason at all to pursue an AUX input "MMI AMI USB-adapter cable" which is clearly old technology.
I have been tinkering same thing as well . My car came with the older unit . I think NTG 5.1 S is the way to go . You can buy Android Auto supporting aftermarket units (without changing the multimedia display) in which you can get an extra USB port besides 3.5 mm jack if I recall correctly . It 's going to be much cheaper to update NTG 4.5 to NTG 4.7 or 5.1 My route is to go keep OEM albeit aftermarket units give you more for less money

I only have one USB port between my front seats.
The only way to play music from the USB port is to connect a mass storage device, e.g. a USB Stick or a USB disk.
I can not stream audio from e.g. an Iphone or an Android unit if I try to connect them to the USB port.
May I ask you if you can stream from a phone, iPhone or Android from any of your USB ports?

I'm the wrong person to ask this, as I use my phone to text and place phone calls, nothing else.
Growing up with a 9" BxW TV, I've maintained as an adult that I will never watch TV on a tiny screen ever again. This goes for streaming music (via BT, tried once in MB) or TV shows. So, I use my phone for its original purpose, only. My phone is not an iPod for me.
I'm amazed, but not surprised, that MB made so many subtle changes in the same cars sold in different countries (one v. two USB ports, SD card slot or not, etc). Very expensive to make so many non-standardized parts across all models. No wonder why MBs are expensive.
BTW, there are dozens of short threads on this forum about AUX inputs, and whether they work or not if retrofitted. Do a Title search on the term "aux" and look past the "aux battery" threads to find the audio aux topics.
The threads are short because those who have retrofitted AUX audio inputs found that it often created other problems or did not work as desired...
@Whomee I have exactly same situation one USE without AUX and have same question since thread is already one year old I was wondering if you found solution?
