It is rooted because thats the way Malaysk does it.

Install v.3.30 whether you upgrade or not - its always best to run the latest MCU, remember to go into factory settings and press "export" this will get your mcu.cfg, flash this with the new MCU, its a file that memorises your MCU settings.

I might be a jerk, but can you point me in the right direction from where i can download the v.3.30?

PX5 2+32 Android 6 for sale

I do have one of those, PX5, 4GB RAM + 32GB Flash with Android 6.

I bought it to upgrade my Android head unit which came with a PX3 2+16 CPU card. It turns out I like the launcher that came with my radio better...

The PX5 is a better product but to me, the differences are down to personal preference.

It might as well benefit somebody, it's doing me no good sitting in a drawer (still in the original bag)

Here is my review and comparison of the two boards:

https://xdaforums.com/android-auto/android-head-units/report-unit-px3-2gb-16gb-android-7-1-2-t3726311

Here is a picture:

[IMG="PX5"]http://fd745e5.online-server.cloud/uploads/MTCD/PX5-1.jpg[/IMG]

I am in the US, price is $40 + shipping. UPS is $8.00.

If interested, email me at 4rt.dw8.5t4wr@gmail.com for more info.

Update: the core board has been sold!
[MTCD Android Head Units General] tvladan:
Thank you for the replay! Unfortunately the 40$ board is out of stock ... Not having the patience to wait for them to restock (if ever) and knowing that shipping from USA to Romania (where I live costs a small fortune) i ordered the 114$ WITSON Android 9.0 PX5 4G RAM +64GB Flash Coreboard For Android DVD gps unit from aliexpress. Hope I'll manage to install it and get it working. My 2Gb px3 is slow as hell and annoys the hell out of me every time I try to do something else than listen to music on it. Once I'll start the upgrade process (probably a month from now when it will get shipped) I'll post back the results!
[MTCD Android Head Units General] Didier99:
My board is a Witson too, I paid $100 for it 2 years ago.

If it's anything like my unit, installation will be a breeze. Pop two screws and the SMA connector for the GPS to free the board and you are done. My unit had the DVD so that was another 4 or 6 screws just to get to the board but access is very good.

Good luck with the swap and getting your board. As far as I can tell, China's businesses are restarting so you should not have too much delay. I have printed circuit boards assembled for me and they were supposed to ship just before the Spring Festival (end of January). They missed the window and went on vacations, then the virus hit. The factory restarted slowly Ferbruary 17th and my boards will ship this week. Keeping my fingers crossed...

As a side note, the only annoyance with the MTCD and MTCE units is the Bluetooth with WiFi. If you are tethering the radio to your phone over WiFi and you get a call, which the Bluetooth radio will pick to route it through the car's speakers, the audio is choppy, not good. I believe it is because unlike on a phone, the Android head unit's Bluetooth is not directly handled by the main CPU. Since Bluetooth and 2.4GHz WiFi occupy the same frequency band, they have to use what's called "managed coexistance" https://www.lairdconnect.com/resources/white-papers/bluetooth-and-wi-fi-coexistence. This can only be managed when WiFi and Bluetooth are handled by the same processor. Since Bluetooth is handled by a separate chip (the MCU, so that the Bluetooth can wake the radio even if it's turned off), there is no easy way to manage coexistance.

I am going to try a 5.3GHz WiFi USB stick in the Android head unit since my phone can tether on that band too. That should eliminate the problem.

upgraded from px3 2g to px5 4g success

Today I finished upgrading my HU. It was a px3 2g mx2 device and it was laggy as hell so I had enough of it.

The process was relatively simple and without much hassle.

The board I used for upgrade is this one: https://www.aliexpress.com/item/32814725689.html?spm=a2g0s.9042311.0.0.4d0d4c4dyfZxK4

Steps taken:

- ordered the board, which came pretty fast via DHL. (5 days from China to Romania, including customs processing)

- updated the MCU from 2.75 to 3.41

- took out the HU from my SantaFe, disassembled it and took out the old board

- soldered the gps wire from the old board to the new board (it came with a really short wire)

- placed the new board firmly in place (had some troubles with the screws being to short, fixed that by using some longer screws)

- mounted the HU back on the car, everything started up ok, gps, bluetooth, wi-fi, sterring wheel contros, all work as they should, right out of the box.

- got rid of the annoying px3 lag :) The new board is an octa-core with 4g of ram and stock android 9. It runs as smooth as it should.

Today I started to install hal's v4 mod ... still working on setting things, but with no major problems. Happy customer here :))
[MTCD Android Head Units General] Fakken:
Hey. I can't find any KBT 3.3 or any KBT at all in your links. Maybe i'm blind? :D

LE: Nevermind, i just checked the cross compatibility thread and KBT is listed there.

So, theoretically i could use any of the MCU's available from the list in the first post of the thread, right?

Do you recommend a certain one?

LE2: Just flashed MTCE_HA_V3.45.rar and it works great on KBT device.

I saved the mcu config file, but i have no ideea from where to flash it. Good thing i remembered all the settings :))

I have a 1GB quad-core RK3188 which originally had MTCD_HA_1.63c. I updated it with Hal9k_'s Nougat ROM 2.5 yesterday and came across this post. I'm sure I can install this PX5 4+64 but do I need to update anything (MCU) before I do?

Still thinking about it as the speed of my current system is already ok but in case I encounter lags or issues :).
[MTCD Android Head Units General] marchnz:
Just MCU.
[MTCD Android Head Units General] andoy:
What MCU should I choose if im now using Hal9k Nougat?
[MTCD Android Head Units General] typos1:
The latest HA MCU you can find.
[MTCD Android Head Units General] andoy:
Ok, i thought there was some sort of compatibility that i may not be aware of so looking for someone to point me in the right direction. But thanks!
[MTCD Android Head Units General] typos1:
The only compatibility is the "HA" bit.
[MTCD Android Head Units General] andoy:
Right, figured it out. It's the dmcu.img file. Found the folders for all the MCUs.

Pretty new to this (updating of ROMs etc) and I thought that since I updated my ROM, it has something to do with it. But it's totally different.

Thanks!
[MTCD Android Head Units General] typos1:
Make sure you go into factory settings and use the "export" function before flashing.
[MTCD Android Head Units General] andoy:
Updated! Everything is so smooth using hal9k_'s nougat so i'm going to stick with it for now up until i get any form of slow performance. But already have the px5 4+64 android 10 saved in wishlist ü.

Thanks again typos.

I am also interested in this Witson PX5 upgrade. For the early upgraders that receive the board:

Can somebody please post pictures of the board TOP and Bottom views.

Please, post the experience of the upgrade and the unit where you are plugging it.

I own a Joying MTCD PX3, and I am willing to install this upgrade. The Joying has the PX3 board soldered (not connectors) to MCU, so this will require some "unsoldering" skills, and soldering to MCU the connector that matches with the PX5 Board (72 pin, 2 rows, 100 mil (2,54mm) pitch).

Looks like Malaysk is already developing custom ROMs for MTCD PX5, I expect it will work with this upgrade board :

i ordered mine too

i got my head unite dead , starting by hanging, or stop reading the SD cards which i used to fix by rebooting it, then all of sudden it's dead , just a black screen and blinking once buttons if i push the reset hole with a pen tip, after searching briefly , i got to know that PX3 coreboard is supposedly the reason, so i decide to buy a PX5 instead of the PX3 as fix and upgrade two in one. wish that PX5 board will fix my problem and bring my unit back to life
[MTCD Android Head Units General] anan01966:
[MENTION=424165]chaps[/MENTION] please update when you Change board.
[MTCD Android Head Units General] chaps:
Fitted the PX5 board today. One problem I had was with the heatsink. I had to remove one of its screws as it was preventing the board from sitting flush. The original mounting screws that hold the daughter board to the main board were also too short due to the heatsink, so I swapped them for longer ones from the chassis.

Everything else went fine. In use, it is night and day better than the px3, probably due to the 2gb of RAM. A cold boot takes probably less than half the time of the px3. There is no lag, I have left all Google services running, and I've side loaded Android Auto, and this works fantastic with voice activation.

I've also noticed the built in DVR app work properly now. On the PX3, it recorded in 480p 4:3 mode only. The new version records in 16:9 @ 720p which is what my camera runs at. I can also set the recording time for each file (5,10 or 15 minutes). It also records my current location and time (the old one always reset to the same time and a chinese gps location?).
[MTCD Android Head Units General] Nomader0:
How does sleep with? Does it turn off?
[MTCD Android Head Units General] chaps:
Same as the px3. I take the key out of the ignition, it keeps playing music etc until I open the drivers door, whereupon it 'shuts down'. It is now in standby mode and will instantly boot up. If I don't return to the car for an amount of time determined in the settings (mine is set to 30 minutes), the unit shuts down fully and requires a full boot. This is my observations anyway.
[MTCD Android Head Units General] techo91:
Strange, I thought PX5 units do not shut down completely. Maybe it´s a MCU dependant after all, which is not a bad thing if the unit starts very quickly. I see that many people here want exactly that.
[MTCD Android Head Units General] chaps:
I have downloaded a newer firmware and MCU update. I'll install them and take note of how it works.
[MTCD Android Head Units General] AndHead:
Received mine today, just replaced the SoC and everything running fine.

Really happy about the speed compared to px3.

It is still in my test bench and not in the car. (Have to build my custom canbus/music player apps first for PX5)

Sent first email to Bob 08.05. so everything went really fast.

(Bricked my Xtrons MLT PX3 MTCD with custom image, so really needed this :)
[MTCD Android Head Units General] Nomader0:
What do you mean by custom canbus apps?
[MTCD Android Head Units General] etulio:
Which brand is your Headunit, I mean, the Version MCU in Configuration?

By your comment about the brick, it looks like it is an X-Tron, but I am not sure who manufactures X-Tron (It might be Witson too).

With this information we may verify if the mix of Witson PX5 with other MTCD brand is working.
[MTCD Android Head Units General] AndHead:
It is Xtrons PF75OLOA (MLT code for MCU)

So yes, at least with mine it works, need to of course put it into the car to see that everything runs 100%.

(Of course before ordering I checked that my HU had the Android SoC not soldered but with easily removable 'pluggable' connection)
[MTCD Android Head Units General] chaps:
I can confirm - unit goes in to low power mode on leaving the vehicle for the amount of time set in the 'extra' settings. It fully shuts down after that.
[MTCD Android Head Units General] AndHead:
I have Opel Astra H car and the canbus app has very basic functionalities for it. (44 is the number is factory setup for my canbus)

So I decompiled the app and created my own based on it.

Only small things added:

- Send radio stations PSN name, not the freq.

- Send artist and track name instead of only the time.

- Scroll the text to fit more.

- Stop sending to car display when in sleep mode.

(And Lot's of things not for type 44 removed.

And so on, still very much work in progress and only for the 44 type canbus.

Also I use as music player custom app compiled from Cyanogenmod sources with the headunit functionalities added. (So it is a replacement to the std music player)

Also doing custom radio app based on the one from the PX3 Android 7 beta build. (Liked the visuals on that one)

Again all still work in progress, even more now that I 'have' to adapt them to Android 6 and PX5 'specialities'.
[MTCD Android Head Units General] Nomader0:
Nice work indeed!!!

Is everything related to canbus inside canbus.apk?

---------- Post added at 08:20 PM ---------- Previous post was at 08:02 PM ----------

This is very strange indeed. As far as I know, PX5 units don't even have the setting to change the sleep time, it simply does not exist on the settings.
[MTCD Android Head Units General] AndHead:
Mostly, it also enables/disables the two other related apps (car info/car settings) based on selected canbus model. (And in some cases also based on the manufacturer code)
[MTCD Android Head Units General] typos1:
X Trons sell units from several manufacturers, there are no "X Tron" units, there are no "Witson" units, Witson are also sellers and sell several different types.

We already know that PX5 SoMs will fit any MTCD, there are no "Witon PX5" the PX5 SoM is the same for all MTCDs.
[MTCD Android Head Units General] chaps:
Mine does. Under Android settings/extra settings/ACC power. It is a Witson unit (MX MCU).
[MTCD Android Head Units General] Nomader0:
I guess it is the mcu that is adding this to Android settings.
[MTCD Android Head Units General] typos1:
This behaviour will be down to your car's CAN Bus system.
[MTCD Android Head Units General] Nomader0:
Can bus has nothing to do with that.

The car cuts the 12v acc then the head unit starts sleep procedures..

Some cars cut the 12v when you take the key out, some other when you open the door, some even have a delay. It depends on how you wire your head unit.

Read the thread.
[MTCD Android Head Units General] Kalti94:
I just got my PX5 Board and pluged it in. The performance of the radio has more than doubled.

When opening, I also soldered 2 external wifi antennas, so that the wifi reception even reaches the hotspot in the near building. A small adjustment was necessary. The PX5 board has a cooler which conceals a mounting hole on the motherboard. This I have drilled bigger(but even without this aditiona screw, the new board would keep it perfectly safe but I just love the perfection)

[Edit: Pictures of the old PX3 Board mounted. Of course i mounted the PX5 with the cooler!!]

[MTCD Android Head Units General] martrobgray:
Dec did you contact Witson through the email address on the website bob@witson.com? I want to get a board in and fitted as I'm getting it in the ear from the wife how slow it is on a daily basis.

Have you fitted yours yet, is it a worthwhile investment?
[MTCD Android Head Units General] Dec64:
Yes i just emailed him and he sent me payment invoice same day, dispatched soon after.

Fitting it was a little fiddly, it is not difficult at all, mine was just a bit fiddly with screws as I have a dvd/cd reader screwed and mounted above the main motherboard that needed removing. Then just unplug the board and plug new board back in. The new board came with a heatskin on top but my old one did not have one, therefore the screws would not work to screw the newboard down if I left the heatskin on, so that came off.

Overall 110% worth it, now radio instant starts as soon as the key is in, less then one second. Everything is 100% faster, radio stops when media plays, gps apps load snappy. All for $100 and unscrewing 5 or 6 screws.
[MTCD Android Head Units General] techo91:
You removed the heat sink to be able to mount the new board?

Mine also came today I was informed. When I come back from work I will install it and see the difference.
[MTCD Android Head Units General] martrobgray:
Cheers Dec,

Sounds awesome, I've got no problem ripping the unit apart, more than confident in that area. I just need Bob to reply and send me an invoice. I want these people to take my money....:laugh:
[MTCD Android Head Units General] Dec64:
Yeah it was held in with two or three screws, just removed them. Heatsink will only help with 1 or 2 degrees of cooling and I like in the UK so nothing too hot. If it was hot outside all the time i'd consider buying some longer screws from a hardware store. The difference is night and day. PX3 was not fit for selling really.

Yeah it seems you have to catch him when he's replying to his emails may take a day but he does send out the boards eventually haha.
[MTCD Android Head Units General] martrobgray:
Well lets hope he pulls his finger out soon. So is your unit now running android 6? are there any changes to the user interface. I am assuming that the board is plug and play or do all settings need to be reconfigured and apps re-installed?
[MTCD Android Head Units General] Dec64:
Yeah android 6, the user interface is slightly different but you can install another if you want, I mostly use android auto. It's plug and play but all apps are reset to the default for px5. Things done in the factory settings behind the password are saved tho, such as bootup logo ect as they are saved in the MCU.
