W221 ANDROID touchscreen...
I am wondering if perhaps there are different hardware versions of this units.
Guys, do your units have an SD card slot or are we all talking about the same hardware?

I have lots of pics and videos on my i.g. @a17844

Just to clarify, I do understand the difference between Wifi (which is actually not the correct term for wireless LAN technology, but whatev.) and GSM. But there are several sources of conflicting information on exactly what these two antennae do.




Hardly difficult to put the two additional aerials in and improves the user experience so much. Why skimp so much at the last stage.
Would.never go back to a hotspot.
It takes longer for the HU to connect and get up to speed, you can't then use the WiFi on the HU for other things, which I do.
You also have to wire in another device which can be avoided and many mifi boxes need manually switching on every time the car is started. More hassle than just connecting the aerials.
Compared to just switch on the ignition and go it's a pain that just does not need to be there.
As for WiFi for others unless you mean for non phone devices like gaming devices who doesn't have their.own mobile data these days where you a re trying to solve a problem which doesn't exist.
If it works for you fine, but is additional complexity for a problem that doesn't exist. Just throw a sim in it and let it have its own connection without having to go through 3rd party devices.

I'd rather have the latest in connectivity tech that can easily be swapped out and updated as well as blanket the entire car than stick a SIM in every device I own...but to each their own.

- Waze works
- Spotify works
- Calls and music via bluetooth through the Android head unit work
- Playing music via DVD or disc works and is correctly interrupted by the BT calling
- Pretty much anything I wanted to work does work
The unit I bought is purely plug and play with one gotcha. After connecting everything, following MegaCrazy's diagram and the literature provided by the vendor, I had no sound. I then noticed the orange fiber optic cables blinking at me, so I removed that connector from the larger COMAND connector and snapped into the new Android/COMAND connector, all works as planned. I don't see much on the fiber options so I thought I'd mention it here.
For now I plan on using my phone's hotspot and see how much I need connectivity. Thanks to all the dudes on this thread, finally got to my comfort zone with price, features and ease of installation.
