Please any help would be very much appreciated. So I have a 2017 Benz C43 Sedan and always wanted apple CarPlay. I ordered a android 12 unit and watched some YouTube videos and thought the process is pretty easy, I installed the unit and noticed my scroll button, track pad, dynamic select, volume scroll, auto stop button weren't working and even the media, radio buttons on the console as well. I thought maybe this was a bad android harness and swapped back all to OEM with the head unit but I still have the same problem. Uploading a video of the problem please any help on what fuses to check would mean the world to me or what could have went wrong. Thank you

My first thought is that the connector(s) for these modules either got disconnected and not reconnected (or possibly incorrectly?) or dislodged somehow.
I would pull the console cover and trace the harnesses/connectors from each of these modules to the connectors for both and make sure your physical connections are good.
You may know this, but swapping to an aftermarket Android screen does not physically have any relation to these 2 items you have that are not working.
Beyond that, it could be the circuit fuse, but why would it trip/burn? Strange.
I took it out about 10 times now and everything is run correctly i have no idea what the issue could be , traced to the trackpad wires and everything is good but my whole bottom half the buttons dont work or light up including passenger airbag light

Sorry to hear that, are you OP by chance? Asking because there is no thread starter label on your post.
Hello,
What I see in the picture is that you should not be able to put the console all the way on the side when it is still plugged in.
Follow my Red Line; if you follow it you will see a White Plug that have a hanger on it. unplug, both ends and look at the wires and I bet you will find one that is damaged.

Excellent point and you're right. Mine will barely lay at a 45 degree angle when laid over, never mind a 90 degree angle as pictured. I agree, it seems like something got pulled out of whack.

Yep, because the problem he is having is controlled by that white plug. If there is any damage to the plug, the console will not work.
Thank you so much for the help ya’ll. I will reopen the console today and have a good luck at the wires today. I am hoping it is that and not something canbus or Sam module i blew

I would it loved to be these wires but cant find any damaged wires Do ya’ll know exactly which wire provides power to the touchpad? No idea whats going on at all at this point
Yep, you have to correct plug, now remove the plug hanger and pull out the black plug part and look to make sure all the PINS are sitting correctly.
All the wires labeled as LEONI are for your illuminated lights. If that cord is damaged in anyway, it will cost around $120 on eBay and or $180 from MD directly.
Okay, yes, check the fuse if the cable looks good. I would also do an continuity test on the PINs from the Black to the White Plug. Just to make sure for certain that there is in fact no break in the wire that you can't see but from what I see from the pictures, they look good but you are also in the right place since that is the cord that powers the center unit. I'm not sure which PIN in the car is the power PIN or what they all do, but I think you can test the wiring for continuity, check the fuse and if everything is still not working, there must be a bigger problem.
If continuity is good, you can sure be 100% that there is not problem with the wiring.
Gave up and took it to a shop and $500 later they fixed the issue and this was all within 10 minutes, it looks like it was a blown fuse as the tech did not even take apart the centre console apart. He told me he repaired the modules but I am pretty sure if it was done within 10mins that it was just a blown fuse. Thanks ya'll for the help though

Bummer man, I told you the exact fuse to check a few posts above. It's the only fuse for those modules.

You want to find a new shop if it charged $500 for 10 minutes work. Even a dealer wouldn’t charge that.
