Did you have to use an AMI/MMI connector? Did you run it to the arm rest? Disassembling the dash makes it a big job; with the console even more so.

Thanks for an amazingly informative thread.

The sight issues I have are 90% of the time it loads in night mode and can not change it to day mode. And when you use the left steering wheel controls it moves the CarPlay menu. Also if you want to use the car radio you lose the sound from CarPlay as it needs to be on aux to get the sound. I use a radio app which is ok as long as you have cellular connection. Hope this helps.

Hi there. Thanks to all the posters here for such great info. I have a 2014 W204 with the AMI/MMI in the centre console and I'm about to install the new generation Road Top unit which has the 3.5mm jack. I would prefer not to have to run this to the centre console if I can possibly avoid it and wondered if you managed to discover if it really is essential or not? It's so confusing because Cadetdrivr managed to get his working without it. I pulled out my head unit and made the connections without doing the full installation and I had no sound at all from the Road Top interface until I plugged the 3.5mm into centre console (via the included adapter). I enabled AUX in the Engineering menu first but I only ever achieved sound using the centre console. Before I start running the cable to the centre console, I'd really love to know if it's 100% necessary. Many thanks.

I'm not sure why mine hasn't worked but before I start ripping apart the centre console, I'll persevere with the Engineering Mode trick and maybe try resetting everything after the changes to try to get it to work. At least I now know that it should work that way. Cheers again.

Maybe if we all ask them, they will listen ?.

Also, it's already possible to use the native MB bluetooth for calls with CarPlay (I don't know about Android Auto) if the phone is also connected to MB bluetooth and you do this:

The downside of the work-around is it tells the phone to try to use a bluetooth headset all the time. It could be an issue if you have another BT headset paired with the phone when not in the car.

A partially fit audio cable could easily explain the issue, especially if its left vs right speakers (the signal is stereo L &R). Unfortunately, if that's the case then I think the first step is to verify that the Joyeauto audio cable is fully seated at both ends.

If the cable is fully seated then it's something else. Examples: bad audio cable, harness wiring problem, or the Joyeauto unit itself.

FWIW, the only email I had for Joyeauto was sales@joyeauto.com and they responded fairly quickly considering the time zone difference.

After I installed mine I also noticed an email for tech support: tec@joyeauto.com.

Is there a detailed set of instructions for this newer version via a manual or video that I can pass on to the installer? Any other specific instructions I should let him know about? Should I get him to install the USB to the centre console for better quality I assume?

The setup went virtually identical to the behavior of my Road Top unit, and was in all respects much improved. I tried to mess up the connection and reconnect to CarPlay several times and it all worked flawlessly, unlike some the 'quirks' I'd sometimes see with the Joyeauto unit. It will take some more testing and playing around with it, but if the initial impression holds I'd say it's a major improvement to one of the relatively weaker aspects of the Joyeauto unit compared to the newer units.

I'm looking forward to playing with it some more before making any firm conclusions.

(Note that I'm also on iOS 14 Beta.)

Anyways, my 360 surround issues are now fixed. So far it’s working 100% after I updated to MCU 20.7.16.18 firmware. New unit also shipped with MCU 20.4.30.17 as did my original.
However, the difference is my new unit has CUST Version: v2.1.0.8.lt.m4_2
My old unit with the problems shipped with CUST Version: v2.1.0.6.lt.m2
Both are HW: BENZ2.
So I’m not sure what the cust versions mean but that might have been the issue for me. I still think it was just defective hardware since it sometimes worked and sometimes didn’t.
The old unit also doesn’t turn on when it’s super hot inside the car.. it’s been 100+F several days in a row here in California and it has been consistently starting up with a black screen. After 10 minutes of AC blasting and cabin cooling down, the screen comes back. Or after several restarts by holding down back button.

Anyway, tomorrow is another 105+F weather, I will see if this new unit has any issues with the heat. Also, the user manual has about 6 more pages and new pictures than the old manual.

My 360 camera runs when I hit reverse, but when I go back to D it will go back to the AA screen, road top not offering new firmware to fix it.

Also in AA Google maps, are you able to move the map around using the controls? I can only zoom in and out
(In carplay that function works)
