Looking back would you guys stick to this upgrade or replace the whole screen with those 10.25" units?

depends.

I like the factory look, the 10" unit looks tacked on. (for some reason manufactures think we like that, hear me M-B!!)

My wife has Factory Android Auto/Carplay in her car and she doesn't like my system because it's not touch screen, the knob is a bit confusing. If you use it everyday then it's not a big deal.

The larger screen would be awesome but the factory OEM screen has very good reflection control.

I'd say it's a matter of taste, preference, effort, and budget.

Unit looks identical to the new units but for far less, ordered one will see if it's for real

I am still waiting on Joyeauto to tell me what the latest update for the NGT4.5/4.7 unit is. Their website seems to have updates for all car models on one page.

It's #1 on the download site. CarPlay Update 2020-3-18

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.

Hi Ian. I also have a W204 so I'm curious to know if you needed the 3.5mm aux cable to be run into the centre console AMI/MMI port via the adapter or did you find that simply changing the AUX setting in the Engineering menu was sufficient for the sound to work correctly? Thanks.

Hi Ian. I also have a W204 so I'm curious to know if you needed the 3.5mm aux cable to be run into the centre console AMI/MMI port via the adapter or did you find that simply changing the AUX setting in the Engineering menu was sufficient for the sound to work correctly? Thanks.

In the end the vendors were wrong and Cadetdrivr was right. The system worked fine using the engineering mode trick. No need to disassemble the centre console.

Thanks for confirming and thanks also to Cadetdrivr who I realised also confirmed this again a few posts ago. 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.

When you try it again also try leaving the AMI adapter connected in the center console, but not the 3.5mm line.

Hi all, I replaced my Joyeauto unit (which worked, but not really... Phone calls were a mess, audio jumped, crashes everywhere...) with a RoadTop one, much better! Sadyl phone calls are still not as good as the OEM solution.

I just saw, that the BMW version got an update with OEM BT Call option : https://f30.bimmerpost.com/forums/sh...postcount=4358

Do you think it is possible to port this over ? I allready asked RoadTop on there Whatsapp chat, sadly they seem a bit "locked up" on further updating the thing (they are ok with fixing, but not adding functionality it seems).
Maybe if we all ask them, they will listen ?

Just to add to the discussion : My sound doesnt work without the MMI Aux plugged in (which is not so bad, as I had to unmount everythig for the roadtop unit and so not much had to be changed...

That would be a useful addition.

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:

https://mbworld.org/forums/e-class-w...ml#post8129703

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.

There is no such setting for Android Afaik.
Problem for me is that there is a smartwatch on my wrist all day and a OBD2 Module for drive logs (because of work), so messing up bluetooth is a bit of a pain...

It would be great to decompile both firmwares / make a custom one (if even possible) but apart from theoretical knowledge, I sadly wouldn't be able to do much...

Thanks - I'll give that a go. I have to work away for the next 6 weeks so it won't be until October that I get to have another go but I'll update here when I do. Thanks for all the incredibly useful information here.

Anyone try the newest firmware upgrade from 08/12/20? https://www.joyeauto.com/support/upgrade/ Curious about what's improved.

I just installed it played around with it for a few minutes. As expected, it required me to re-pair my iPhone with the unit and that's where it got interesting.

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.)

I’m in Perth and installed the road top unit into a 2014 CLA myself (NTG 4.7). The instructions are almost identical to Joyeauto installs so you can use them as a guide. I used a combination of Cadetdrivrs’ instructions and the following thread for CLA specific disassembly.

https://www.mercedescla.org/threads/...015-cla.40239/

I didn’t run any cables into the arm rest as per cadetdrivr.

Space is a bit more limited for the cable harness in the CLA so just have patience. There is a small void below the head unit which you need to tuck as much of cable into before you can get the head unit back into place.

Good to know, thanks for the detailed info!

[QUOTE=mikymerol;8084996]hello do you think it is possible to connect an amazon firestick to our joyeauto interface to HDMI output? thank you all.[QUOTE]

Assuming it is an active port, it depends on how the Firestick implements DRM. If it ends at the Firestick then it should work fine. One way to check is to connect one of the cheap HDMI-USB video capture cards (on Amazon for ~20) to a computer, fire up OBS (a free OS video capture program that is awesome) and see if it can record video and sound then you should be good to go if the Joyeauto interface supports HDMI.

Got a road top unit with MCU MCU 20.7.7.12
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)

Try the latest firmware posted earlier on this thread. You may have better luck than I do. Mine will display 360 camera in D intermittently. Sometimes it works, most times it doesn’t.
I am able to move the Apple map with the knob’s directional buttons vía CarPlay. I don’t know about Android Auto, since I don’t have an Android phone.
Correct, as of now RoadTop does not have a fix for cars with factory 360 camera when transitioning to D gear. Some other models claim it works for them 100%. I’ve had two RoadTop units and both are the same scenario. Not sure if it’s some setting in my Head Unit that is different or something..
Anyway, high cabin temps still cause a black screen for me for until cabin cools enough.

Found it will try tomorrow, as for carplay seems more polished then AA on this unit, response from Road top was unit doesn't support movement of the map in AA

Hi guys! I just woke up this morning thinking: can I get carplay in my w204? Later on surfing the web searching for solutions I’ve found this thread. I have a 2010 model with NTG4, as I understand my best option is the Joyeauto one with the external microphone. Is there any other options I should consider? Thank you!
