Thanks. I usually use my stock BT but was just trying it out and wanted to see if there was something i messed up during install. I’ll just stick to using it for Siri.

Hi ti everyone boys, i'm an italian guy, i apologize in advance for my bad english. I have a w205 C class with idcore interface installed. I have an old update of 2019 I wanted to know which update to install and if only the last one is enough or you need to install all the previous ones. Many thanks in advance.

You only need the most current update but be very careful to ONLY the CarPlay software. On the Joyeauto website the most current version is dated 2020-3-18.

mikymerol

This Is the right update? is it enough to install only this or all previous ones?

cadetdrivr

That is correct. You only need the current one as they include the previous updates.

After you update, lock the car and leave it off for more than 10 minutes. The next time you start the car the current software will be loaded.

mikymerol

Thanks a lot 👍

And for MCU upgrade? I have this version.

cadetdrivr

That's the same MCU version I have have. I asked Joyeauto this question last month and was told that v0.1 was the current MCU for my cars.

mikymerol

which car do you have?

cadetdrivr

I have the Joyeauto unit in two cars with NTG4.7. 2014 E350 (W212) and 2014 GL350 (X166).

Hello guys, i tried insalling the software update using the same method as in the vid and the screen just went black and now the carplay is not working (just black screen) have anyone experienced that before? or does anyknow know if i can reinstall the software using a computer?

inittab

Can’t be done using a computer. You must use a USB key with the firmware on it.

Gatt

ah i see i cant do anything since its just black screen

Reach out to Joyeauto support. Maybe they have a workaround to get it out of that state.

Just to close the loop on this thread, I would suggest that anybody considering installing a CarPlay module look for a next-generation unit.





I don't know if Joyeauto will supply one eventually but there appear to be couple different companies offering what appear to be similar, if not identical units. FWIW, I purchased a unit from Road Top (via aliexpress) as the identical unit from Road Top on was more expensive. (It looks like the prices are much closer now. YMMV)

I wanted to try it out in the wife's GL and the installation instructions are essentially identical except for fewer required connections.

IMHO, these newer units have several advantages:

• Longer, and simplified, wire harness so it's easier to place bundle behind Comand unit
• Uses MB mic for phone calls
• No need to wire mic or AUX cables, but you still may need to enable AUX in the Comand engineering mode
• Unit automatically switches CarPlay to dark mode instead of on a fixed schedule
• MUCH more reliable wireless CarPlay connection. It "just works"
• Much more simplified system settings
• Less expensive

Disadvantages:

• Road Top does not have a website that I know of, so support may be a consideration, including future firmware updates. That said, this new unit is FAR more refined and polished as it is.

Would it drop-in with the connections for the JoyeAuto harness, such that one doesn't need to take the dash apart again?

cadetdrivr

Nope.

(That's why I tried it first on the insanely easy X166.)

Hello guys so I decided to to update the software and and pressing confirm the screen turned black and joyeauto wont work till now just black screen, i tried to install appcore.enc via OTG cable but no success anyone know how to fix that? I messages joyeauto support and they told me to contact my reseller but my reseller doesn’t know how to fix it

cadetdrivr

FYI, the Appcore.enc file is a MCU update while ISPBOOOT.BIN is a normal software update file.

I'm gonna suspect that you may have bricked your unit if neither Joyeauto or your reseller can't help.

Gatt

I guess yeah that what happened, is it possible to update the normal software from an OTG cable or thats only for the MCU updates?

cadetdrivr

I know that the MCU update can only be done via the OTG cable but I don't know if the normal software update can use either USB connection as I have always used the USB connection on the wiring harness.

Gatt

whats weird is they told me the update I tried to install was the wrong file, the update that I tried to install was the first one that was posted on 2020-3-18

cadetdrivr

I'm wondering if you dowloaded the MCU file right below that one by mistake? MCU files are *.enc while software files are *.bin.

In a previous post you said you were trying to install appcore.enc, so *IF* it was appcore.enc it was the wrong file.

Gatt

no i tried to install the normal software file named ISPBOOOT and that lead to infinite black screen, after connecting my reseller he gave me the file named appcore and told me to install it via OTG cable from the Carplay box and still nothing happened

nycsr20

Could it be possible that the file was corrupted somehow? Maybe reformat your thumb drive and download a new copy of the ISPBOOOT file and try again. Maybe try stepping back with an earlier version of appcore. I updated about 20 minutes ago with no issues.
