Android Auto in 2016 W212
After installing ECO, it said: Install Success, 1 remaining. So I was thinking like yourself, I turned it back off (to see if I could basically) and then when turning it back on again, it stated: Install Success, 0 Remaining.
I don’t think we can record to the OSB, that is to say as you did that it records the VIN. It somehow could I guess, but I don’t suspect it does or has the ability. As always, I Kood-B-Wong





I still would of needed a USB connection, at least for the sound/audio input to feed the Android screen as my car doesn’t have a RCA Aux input (NTG 5.1 has to use the USB for the audio feed).
I need wife’s consent is all, and I’m wanting to go BIG (12.3) and for both of us traveling I need to convince her that she’ll have her own side (split screen) to have her Pandora. I can still have google maps and by CarPlay wireless..... ordering flowers now. 😍
Just as with the OEM Comand, with Vlad's OBD2 solution, you will be able to set your MEDIA (Pandora), THEN switch to the NAV screen (now ACP) screen. Pandora will continue to play. But you will not be able to SEE both together VISUALLY. You will need to hop back and forth between the two. Just making sure you understand that.
You might be able to do more with the full replacement Android screen. But in addition to getting your hands dirty for a couple days minimum, the replacement screen will come with its own downsides, the least of which is the dealer will not touch anything associated with it.

with the latest Android 10 Snapdragon processors, LG HD screens, these things are now finally acceptable, at least to me.

at first the 12.3 looked gaudy, but the more I looked at it... really grew on me, and with a quick glance I can take-in (even at half screen/split) enough info to get my eyes back on the road quickly.





If your wife drives the car, hopefully she's taller that 5"6". Any shorter and she won't be able to look over the screen to see the curb. Can you spell Curb Rash? LOL

To each their own, but one of the reasons I own a W212 instead of one of the newer Benzes has to do with the interior being restrained and classy. That just turns it into a train wreck. The W212 with CarPlay (or AA) is modern without being stupid looking.
My concern is getting a green flag, the latest and greatest with all the bells n whistles (including screen mirroring, wireless AA/CarPlay for the NTG5.1 is well into the $600’s..... the older units are going quite a bit cheaper, but I’m not going to go cheap if I do it.
flowers ordered. Wine n dine Friday nite planned

ps, I haven’t gone this way, just desire to!

For me? The tacked-on screens in the newer Benz convinced me to buy the W212.

My warranty is up in July of this year. Then I suppose I can install a Pioneer deck if I want. But, I don’t.




1769022401+2129025611+2129025910
the latest version are:
1769027702+2129026011+2129025910
so I'm going to the nearest dealer tomorrow to try and get the unit flashed, then I'll try again with the dongle and will report back on this thread...
annnnd, $190 poorer, but the nearest dealer today did the firmware upgrade, and I drove around the corner, parked, and plugged in the dongle to reenable CarPlay, and plugged in my android auto enabled Pixel 3A, and.... and.... IT WORKS!
SO... just because you have the carplay volume setting on the dealer menu, and just because you have High_CY15_9, does NOT mean you have the latest firmware.....

Awesome news, congrats and enjoy! 👊🏻🍻
i remember seeing this hub with the phone imprint on the 1 side, was it this site? Heck, might as well order that and do it myself rather than another hr drive to dealer, then waiting of course.




At dealer, I had the dealer do the estimate for the new usb hub, that had the part# on it, and, it is updated or actually superceeds the older part# which doesn’t have the phone/tablet image on port 2.
To help anyone else in the future, here’s the results....
‘Mercedes Part# 172-820-20-00-80 dealer price $79.56 + $139.99 labor.
DIYers can search that number with good results. I went eBay $56.43, and brand new, not re-manufactured like so many out there; beware.
My dealer has a big picture window from the lounge looking into the service bays. I watched as my car left, then proceeded outside as I wanted to talk with the tech. Well, he took to the drive thru wash, then I nicely approached him as he parked it...
Nice bearded fellow, could of been on Duck Dynasty for sure. He tells me that the hubs do go bad, and especially when not being used. Not sure about that in-depth, but he said he did a “update pass control unit”. Not sure what that is/was, but I was thinking about my Vlad loaded CP and Eco. Whew... all was good, but I couldn’t tell him about that stuff.
I also got a complimentary map update. Probably of no good to me as I’ll be using googlemaps or Waze, but okay... it was a freebie I guess to make my trip more worth it.
So>..... “Reman Connection Unit” ordered, TBC




just fyi...XEntry Parts Info says my 2016 has A1728202826 "Connection Unit - USB Connector"
and I guess you need two thin metal tools to insert into the slots and push the two release clips towards the middle to get it out. most of my small flat screwdrivers are too thick for the slits.









Wife pre-gave me the green flag to order in the new Android10 12.3” screen. So I have to run a wire to the USB hub and a center console removal is necessary anyways.
