W221 ANDROID touchscreen...
First, as we all have seen, virtually none of the Chinese systems come with any sort of instructions.
After removing the original OEM screen, you reuse one of the plugs for the LVDS connection; you remove the fiber optic cables and plug them into their piggyback harness. The unit comes with its own separate speaker, MIC connection, etc.
While the box comes nicely packaged, again, there isn't a single installation video, set of instructions, NOTHING. So for the less able user, this is not an easy install - and I would recommend other vendors that have better documented solutions. Now to the meat of it:
- What CANBUS version to select under the systems menu? While the code to get into engineering mode is 1314, there is nothing that tells me what version of CANBUS to enter. Any help would be welcome.
- None of the CANBUS displays work - not speed, not anything else. Sure, there are screens that would tell you speed, RPM, etc...but none of them are receiving any input.
- The GPS signal is entirely confused. THE PASS THROUGH DOESN'T WORK. While this is supposed to be a passthrough device for the OEM GPS, there is no real time usable OEM GPS from the original COMAND system. Sure, the screen is there, but it doesn't display your real live location. It's delayed, it lags and it simply doesn't work.
- While at first APPLE IPHONE as a system was apparently live mirroring, once the carplay SEED installed, that was it - no live mirroring.
- The SIM card reception is entirely intermittent to the point of uselessness
- The joystick doesn't work
- If you select the wrong GPS enablement button, you're stuck in one of the android screens unable to go back to the NTG screen
None of the individuals at Navifly / Mekede support listed on their Chinese page reply - not by phone, not by email, not by QQ, What's app, etc.
So in my opinion, this was a well wasted amount of money - some of the other vendors that provide solutions earn their salt by troubleshooting these issues, providing better documentation, etc.
If any of you can help who had experience installing these android boxes could lend some advice, I'd appreciate it.
Thank you!

I had a SMARTY Trend head unit installed in my 221 Mercedes a few months ago.
I haven't found many reviews, but there is information from various people on various forums. I want to share my experience.
I contacted them and decided to find out how it works and if they can ship to the US.
There were a few questions about the device itself.
I don't have AUX but have an NTG 5.0 system. The sound is through a special adapter that was included!
The technical support specialist explained to me all the nuances of my car and helped me to choose a really good quality device.
I am satisfied with it and paid via PayPal. The delivery was fast and took about 11 days.
My question is- has anyone figured out how to change that climate control popup from Celsius to Fahrenheit? Support is happy to answer my questions when it comes to wiring but is silent on this one. Very annoying when everything else works so well.

I wasted a lot of time messing around and researching stuff and watching videos and the only thing that worked was STAR and it took 5 minutes and there was Aux (through the glovebox RCA)
This is NTG 3, NTG 3.5 has the audi style MMI I think
Attached are the wires I received with the unit. I have a ipod cable in the dashboard. Can't see the other side of the cable will have to open the dashboard. Car has TV function.

thanks again for the useful information
Also considering the Joyeauto Wireless CarPlay module as well (seems less complicated to install). Out of curiosity, does anyone know the resolution of the 8" 16x9 OEM COMAND display? I saw screenshots of CarPlay on the OEM screen and it looks surprisingly good for 15yo LCD tech.
