[MENTION=2238164]stefcio007[/MENTION] I got the file from that post my question was from where did he get the file, I wanted to document a bit about the source of that file before trying to update my MCU.

[MENTION=6910408]tbmiso[/MENTION] thanks for letting me know. Will try and update my MCU later today.

*UPDATE* I just finished updating my HU with 2.60 version on my XRC. No problems, no errors. Thank you for the file [MENTION=6910408]tbmiso[/MENTION]

[MENTION=4974080]marchnz[/MENTION],

Thanks for all your help. I am actually trying to now get all audio via the usb digital out from my HU and use that instead of the RCA cables. I might be able to pull it off if only I can figure out how to root the device. (No luck as yet).

If that fails then I will take you up on your offer and start a new thread to pull new RCA leads. For now fingers crossed I can get the USB Digital and root solution.

I know I'm pushing my luck here... But any chance you would be aware of a root solution for this HU? New PX3 RK3188 2GB Nougat. MTCD_MX_V2.56b_1

I won't post further on this topic in this thread as it's off topic. Thanks in advance!!

I have a PX3 with 7.1.2 and 2GB RAM, MTCD_LM - is there a newer FW available? The stock FW is buggy and has some problems.

Thanks in advance.
[MTCD Android Head Units General] marchnz:
Successfully applied MTC*E* HA2.65f to MTCD JY/HA/LM/GS et al. Your mileage may vary.

Flashing MCU firmware is a risk. I doubt you will brick your MTCD applying this MCU however apply at your own risk.
[MTCD Android Head Units General] osmodia:
Thanks.

So you think I can flash the px5 from to a px3 device? What do you mean with mileage?

Where do I find the download?
[MTCD Android Head Units General] typos1:
No, you CANNOT flash an RK3368/PX5 ROM on an RK3188/PX3 ROM, he is talking about MCUs, which are the same for all MTCD motherboards regardless of processor.

I've got a KLD with MTCD but i don't see it in this thread. I see there's some KLD's MCU for MTCB. Someone can help me?

I have been trying to find MCU update for PX5 MTCD unit sold by Eonon, from various threads here it seems to me the following is true but I hope someone can confirm since I am making conclusions from a few different threads:

My Enonon unit is PX5 and comes with MTCD_WWW

According to this post https://xdaforums.com/showpost.php?p=73466312&postcount=2 MTCD_WWW = MTCD_KLD (Klyde)

According to this post https://xdaforums.com/showpost.php?p=73980422&postcount=251 MTCD_KLD = MTCD_HA

https://xdaforums.com/android-auto/.../mtcd-verified-cross-compatible-mcus-t3624724 says that the following MTCD MCUs have been validated as cross compatible on 1024x600 units:

MLT = JY = KD= KGL = GS = HA

So it seems it should be possible to use any of MLT, JY, KD, KGL, GS, HA or KLD MTCD dmcu.img file to update MTCD_WWW after first exporting the current WWW MCU settings?

Should WWW and KLD be added to the mtcd verified cross compatible-mcu list?
[MTCD Android Head Units General] typos1:
Eonon are sellers, not manufacturers so it is only "sold by Eonon" and the sellers is irrelevant for anything other than warranties. The 3 letter code tells you who makes it. I ve not heard of "WWW" before and if you cant find any WWW MTCD MCUs then try flashing a KLD MCU and if that doesnt work use the "Cross Compatible MCUs" thread to change it to a different manufacturer, dont worry if no one has changed a WWW MCU unit before - [MENTION=4974080]marchnz[/MENTION] will give you help if you have any problems. Note - go to factory settings and hit the "export" button, this will put an mcu.cfg (config) file on your sd card, copy it and keep it safe, flash it along with any new MCU.

Try it out and post findings in cross-compatibility thread.

Got an Erisin 3015 with PX 5 board. This is a LM unit out of the box.

But..., radio reception is much better with the MCU MTCE HA_2.65f than with the LM 2.55.
[MTCD Android Head Units General] Musicman1973:
THX, but i have installed LM 2.62_1 !
[MTCD Android Head Units General] typos1:
You can install ANY KLD MTCD MCU, also you can install MCUs from other MTCD/E units, see the "Cross Compatible MCUs" thread.

You have an LM unit, there are no "Erisin" units - Erisin are a seller only.

Interesting to know that that the HA MTCE MCU improves reception.

[MTCD Android Head Units General] typos1:
Do what. I am simply telling you that ALL MTCD/E units, whether RK3188/PX3, RK3368/PX% or Intel Sofia use the same MCUs, this is a fact, there is nothing for me to "try".

Put the MCU on an sdcard, put the sd card in the unit (use the "GPS" slot if you have 2) the unit should autodetect it and ask if you want to update.

You can use any RK3368/PX5 ROM, I ve never heard of "WLGK" before, if you cant find an WLGK MCUs then check out the 2Cross Compatible MCUs" thread.

No. MCU updates.

The file says MTCE, but I believe from another post of yours you had a MTCD?

EDIT: Was just reading in another thread, the MTCD designated units are now being named MTCE, so it is basically the same thing? I knew they were compatible with ROMs but was not sure if the MCU translated over as well.
[MTCD Android Head Units General] typos1:
MTCE is an update to MTCD, just as MTCC was an update of MTCB.

Unlike MTCB/C units most MTCD/E units can run MCUs from other MTCD/E manufacturers, see the "Cross Compatible MCUs" thread.

[MTCD Android Head Units General] typos1:
Theres no such thing as a "PX5 MTCD MCU" - all MTCD/E MCUs are the same, regardless of processor type.

As MCUs are spread over so many threads its best to google "XDA MTCD KGL MCU", or in actual fact "XDA MTCE KGL MCU" as the latest MCUs are now MTCE, not MTCD.
[MTCD Android Head Units General] stefcio007:
Google refuses to let me search XDA MTCE KGL MCU even if I put quotes around MTCE. Do you have links?

Search the whole thing in quotes links directly back to this thread. It's probably why people keep asking here.
[MTCD Android Head Units General] Danno1975:
I think I found it mate, first page. I think if you are a programmer techie or been on here a while it makes sense of how it’s all added here, it’s all well intentioned but for us newbies it’s a bit of a mystery, Looks like this is the one and it would appear that as far as KGL go the latest is June 17 MTCD_v2.54_5.

Someone kindly noted to me they have used a newer version for another brand MTCE 2.7 or something that worked. But I’m not going to bother till a KGL one comes out as I’m more for fixing bikes than meddling with computers and if it screws up I’m out of my depth (for now).

Also it was noted that Oreo may be coming too so I’ll hold fire till that’s available and do the lot as currently my unit seems brilliant.
[MTCD Android Head Units General] typos1:
Not really, its a whole search, I cant s end every link !! Never heard of google refusing to search for something before !

Thiose are links from Yandex, not XDA.
[MTCD Android Head Units General] Danno1975:

The latest I've seen is 2.54 for KGL (yes, I have links) but that was released on June 15th. Did they stop developing for KGL?
