COMAND 10.25" Screen Upgrades
The call delay is certainly a big issue if OEM BT for calls can't be used at the same time it's connected to the screens BT adapter. Looks like the USB AUX dongle is the easiest way (only if you could get one that works with your system) to free up the OEM BT for calls. Too bad it's unpredictable as to which USB AUX dongle would work as there's many more fails than successes. Guess i'll hold out a little bit longer...
If we couls only figure out how to activate the aux port in the w205, then this issues that exists in the Benz OEM system is solved technically, because we could bypass the cars BT system and just use the new units.

Do you by chance know of anyone videos out of some one that has installed this in a w205 that does not have any existing AUX ports?
The only way I've found to fix it is to open the Android settings, go in Location, and change the Location mode to WiFi only, wait a sec, then set it back to device or high accuracy. Then the GPS Test app will see the satellites again, and navigation will work again.
Has anyone found a permanent fix for this? Thx.

Just install Torque and connect.
These OBD2 plugs are cheap on AliE

Explained this several times across the threads now. If the manufacturer won't remove the restriction then rooting and doing it yourself is the only real answer. Unless someone finds a compatible unit, but these are usually the $100+ range ones.

From my sode, I put it under the cover of the front speaker, and the GPS catches satellites when I go out from a tunnel.
I use waze as well.
That last "losing GPS after a while" helped me find a solution that seems to work: it's a quite common bug in Android 6 on lots of smartphones, where the battery saver accidentely kills the GPS reception. And apparently disabling battery optimizations on all GPS related apps&services seems to have solve it.
To do so:
- Open Android settings,
- Use the search for battery to open the per app battery optimization (it's hidden from my menu, I had to use the search to open it).
- Disable everything that seems to be related to GPS, especially some system service with a weird name that I forgot.
Very late edit : it was the antenna placement. It was stuck behind the screen vertically, and the roof was probably hiding it too much. Now that the antenna is placed horizontally and further in the front, all is fine.

First, thanks for all the sharing in this thread. It is really useful. After digesting all the info, I ordered the latest version(4G RAM + 64G ROM) of this head unit from taobao. Just got it installed on my C300. It took me sometime to find the right resolution of OEM system, after that, it is running great. Then only issue I have is Bluetooth connection. I cannot get it connected to OEM system. Will need to do more troubleshooting tomorrow.
I checked with Rock at carlife, they also have this model available. And had posted new video on
After installation.
3GB memory!?
Firmware version.

Seems like a scam? Other have pointed out how the Android version, that's supposed to be 7, is actually 6.x. They simply hacked it to say 7.0. And now yous is supposed to be 4gb ram but only has 3, or 2.8? Something's fishy. I'd call them out on it and see what they say.

Do you figure out to make "ok Google" works on the head unit?
On my device, the voice match option is locked, so I cannot activate "ok Google" on any screen.
When I start the Google app, the "ok Google" works from the Google search interface... But it will be terrific if it can works from any screen.
Same on your side?

I looked at their install wiring diagram and instructions and compared it to the back of my headunit and it matches to the corresponding empty slots on the adapter.
The OBDII activator that comes with it seems to activate the AUX menu. Anyone try it?

Unfortunately, i cannot give a try. my car model is 2015, and the datasheet of the adapter specifies 2016 and above.

His answer:
"Unfortunately this adapter was not tested on C class.
The following item will work

This module is more expensive and seems to be more tricky to install than the other one. But no OBD upgrade.
i'll wait for the USB adapter i ordered few days ago, an if I still have delayed sound like with the BT one, then I'll think about this module.
just want to share a very cool app that auto activate the Wi-Fi hotspot when the phone is connected with Bluetooth to the car (or any other device, you can choose).
Carspot Wi-Fi
Enjoy!

Please let me know your findings. I was playing today with the embedded bt of the display to connect it directly to the head unit to see if it made any difference. But I wasn't able to connect it.
I am just wondering why I don't have any audio delay if I connect my phone and I do call somebody.
Zippi which adapter are you trying?
