I've recently bought and installed a upgraded becker module in my W204, and I wanted to share thoughts and advice on it, incase anybody is eyeing this upgrade.
(For reference, I've got a 2013 W204 with the NTG4.5 system)

I bought my module off Aliexpress and it costed me right about $100.
The instructions for installing the module were very short, and did not cover any troubleshooting.

Installation (Car can be both on and off while installing):

• Remove your original becker module (Found in your glovebox).
• Install new module.
• Press NAVI to access the setup screen, and make sure the module is working.
• Press DISC to go back to audio screen.
• Go to bluetooth.
• Do not hit "Search For BT Audio Device" (This way of connecting will always fail).
• Rather hit "Connect Via BT Audio Device".
• You will be promted with a screen that says "Ready for bluetooth connection. You can start searching for MB Bluetooth".
• The becker module will ask to connect when this screen is open.
• Wait for the becker module to request a connection (This usually takes 10-20 seconds).
• After the module has connected to the car's bluetooth, you may go back to the setup screen by hitting "NAVI".
• Here, you will connect to the module from your phone via bluetooth/Apple Carplay.
• The module will usually be called "CAR-BT-XXXX".
• After connecting to the module, it will take you to your Apple Carplay screen.

The installation is fairly simple, and is definitely a worthwhile modification/investment to modernize your interior, without having to install a aftermarket screen and keeping the OEM look.

The only point of critisim on this module so far is a very minor one:
You do have the option of installing a reversing camera with this module, but if you do not have one (like myself) the screen will go black when the gear lever hits/goes past reverse. Though it only goes black for a split second.

Let me know if you have any questions, maybe I'll be able to help out!

I have a 2014 C350 and am unfamiliar with the Becker module. Can you provide a picture?

Also, can you provide a link to the module you got?

Lastly, the font color for what you wrote after the bullets is nearly invisible on a light background. Can you set the font color to black?

Thanks, this looks like an awesome upgrade.

Thanks for the heads-up! Changed the font color!

This is the module I bought: https://www.aliexpress.com/item/1005...32bcf19cLm4Smh

Here is an attatched picture of what the module looks like, its found at the very top of your glovebox.

I don't have the Becker slot. My audio is Harmon Kardon. Bummer. I have RoadTop in my SL, but was looking for something for my C350.

Do you have navigation on this 350?

Yes.

I've had Road Top in this C350, but it's my wife's car and she didn't want CarPlay.

Nice upgrade! Were you able to use the voice command prompt via the steering wheel?
I have the EU version of the Becker map pilot module installed and loaded with the outdated 2016 NA map. But as a solid Android user, I'm sol. Neeways, Google or Waze maps work well for my needs.

Yes! The voice control button on the steering wheel works, it activates Siri, and I can do any request that I’d like.

You do get these modules for Android Auto too, definitely a good upgrade to modernize the infotainment screen while keeping it OEM!

I have the same car. Just made the same Update. All i Worning perfect except the Sound in navigation.
Any clou og what i havedone wrong?
😅

Did the new unit include cabling to the Car Audio connector? And obviously it fit correctly.

I have a 2008 C350 NTG4.0 system and am having a very difficult time finding a Cable or Connector to interface w/ the car's 18 pin male that had connected to an iPod box behind the glovebox.

Same here but I do have what appears to be one in the console. You might look there.
