I'm located in the US, and its est of arrival is in April. Did you all go with the standard free shipping, because I don't really want to pay and extra $100 for faster shipping lol.

Any ideas on how to fix that electrical issue? I was able to get the HU back flush, and everything works, but the left front speaker still sounds blown.
Also where did you guys put the box? did you put it in the Glovebox? I'd prefer to keep it somehow out of the glovebox.
Also there is some weird scan lines happening on my display, but only when I'm in the factory HU, when in Carplay it doesn't happen.
I've attached a picture of my firmware version as well.
Lol I spent like 5 hours struggling in my car today, so any help would be awesome, haha!
Thanks in advance!
UPDATE: 03/15/21
So I was able to get the box and installed and placed below the glovebox and below the footwell lining. Everything went back fairly smoothly lol.
Still running into the audio issue, and the scan lines on the normal command screen are less frequent but still happening. Other than that everything works pretty flawlessly. I also routed my calls to use the MB mic/bluetooth call per @S550e suggestion- and the calls are much clearer.
Overall very happy with it, the only thing I wish I could do, would be to improve the resolution output of the kremersino box, it looks far more pixelated than the normal command software. If anyone knows how to do this, let me know

Not sure about anything as far as the blown speaker, fuses, and/or electrical short. I know nothing about that kind of stuff, sorry.
I haven't received it yet but I'm trying to prepare for the installation and after reading the thread + watching some installation videos, I have the following questions:
1 - The big box (not the small one that sits behind the COMAND module) is installed betweem the bottom of the glovebox and the footwell trim? Or is it preferrable to keep it within the glovebox compartment itself? I am not sure which is better and I'm concerned that having it sit between the footwell trim and the glovebox might produce noise/vibrations.
2 - My car doens't have the MB Media Inteface, it actually has an AUX jack on the right side of the glovebox. When we talk about using the AUX entry, does the box plug-in into this glovebox AUX jack or do I need to enable the "internal" AUX entry that's on the COMAND box itself, making the glovebox AUX jack useless?
3 - Has anyone actually tried Android Auto/Wireless Android Auto? Michael from Kremersino tells me that the box now also supports Wireless Android Auto and I was wondering if anyone has had any experience with this.
I am thinking about trying to install it myself due to covid restrictions. I am a bit of a novice but have already tackled some minor projects such as fixing my sunroof (broken cog on the sunroof motor) and fixing my rear AC vents.

I have a question for you specifically since you are running a newer software... my one and only issue with this carplay box is that the turn-by-turn direction announcements are way too loud. It is very distorted and sounds like the speakers are about to blow (yes it is that bad). So I have disabled all turn-by-turn directions for now until I find a solution.
I was wondering, in your 'Common settings' page there is the Master Volume (which I have) and Navigation Volume (which my software does not have), does that control the Apple Maps and Waze volume? I'm guessing it should because on my unit there is no built in navigation system or application so my only other thought would be the turn-by-turn direction volume in Apple Carplay.
Please let me know if that 'Navigation Volume' controls audio such as Apple Maps or Waze. Then I would be interested in updating mine or purchasing a whole new unit. Thanks!
Here is the setting I am referring to. It is a picture that you took:




I did find this File Download Section on the Kremersino website. Password 1234. Not seeing anything for 4.0 though. Scanned through really quick. Let me know if you see otherwise

. All in one my best guess is a loose cable somewhere, they needed to be pushed real hard to fit correctly. For me the resolution is also stunning, I am amazed

I have an MMI port which made it easy for me to install it in the glovebox, with only an AUX on the other side, or cutting a small piece out of the top of the glovebox, well I wouldn't have tried... I only installed it in the glovebox for quick access in case of overheating or something (I did not experience any, working really fine), and my glovebox has a divider which makes it useless to store stuff in it. Since I installed the box I did not even open the glovebox (only when I'm showing the friends where the magic box is
). For first try as @S550e did, maybe under the glovebox would be nice, I'm not sure how much we W204 owners have compared to their E classes, maybe it does not fit, you will have to try, it's not a hassle
.
They definitely ship the current boxes with a newer software. Thanks!
Also caved in and switched from Android to iPhone due to a good sale on the iPhone 11, so less worried about Android Auto at the moment. Excited to enjoy wireless carplay on a 11 year old car! Haha.

I agree that the infotainment system goes through a HUUUGE upgrade with this, I don't even know how I was able to live without it
1) In the 2010 E350, there is no USB charging port. Did you add that somewhere e.g. in the center console or the glove box?
2) How much should we pay an installer? What would be reasonable?
Thanks
