YeeHung W204 Android 11 12.3" install (Built-in CarPlay android auto) 

Dear, i think your 2014 c250 is a NTG 4.5, following product fit your car. www.amazon.com/dp/B0BNPY32GX?ref=myi_title_dp Please note that if your original radio interface does not have the AUX menu, you need to activate it to get the Android sound.

if your 2012 c class is a NTG 4.5, yes, you can connect the AMI cable get the android audio.

Don't worry, I'll fix it for you. Please send your purchase order number to our after-sales team: service@yeehung.cn

You don't show connecting the audio? e.g. via Aux or AMI. Reply: If your has the AMI, you must connect to the AMI, if you don't have the AMI, you don't need to connect anywhere. Presume that to hear anything from Android you have to select the input on the OEM screen? Reply: Yes, you must select the AUX menu in the original car interface. Also, does this work with the original microphone? Reply: Sorry, you cannot use the OEM microphone in the Android menu, but you can use the original microphone normally under the original car function.

@pempcar thanks for the reply. The microphone is surprising as you can intercept its cable just like all the other cables. The original microphone is excellent and is already nicely routed so please consider trying to use it. The small Android module that replaces the Becker nav module can use it so I am sure you can 🙂 On that note, since the satnav module is able to play sound via the standard HU I would imagine it should be possible for an Android unit to use the same mechanism i.e. no need to route the audio via aux/AMI/Bluetooth 🙂

@@richf1182 Thanks for your advice. If the Android sound is to be input to the original car host, there must be a channel to go in.

@pempcar indeed and there is one that the OEM removable satnav module (Becker) that is located in a cradle in the glove box uses. This is how the replacement Android module (I think one brand is Carabc) works with the original microphone so if your loom patched into that feed it should be possible. The Carabc module uses Bluetooth for audio but that shouldn't be needed as the Becker module uses an automatic wired input.

​@@richf1182 I will pay attention to the Becker module you mentioned. We sell NTG 4.5 CarPlay MMI BOX, which uses OEM mic, www.amazon.com/dp/B0CGLLMX24?ref=myi_title_dp

Yes, there may be a better way to resolve the location of the GPS antenna in relation to the 4G antenna. Thank you for the suggestion.

Dear,if your w204 is the ntg4.0, it has the ami interface, you need connect the audio cable to it. if your w204 is a ntg4.5, no aux menu, you need Activate the AUX menu.
