[MTCD Android Head Units General] BlueVan:
Thanks for this useful report. I have one question:

Are you sure the fan turns off when the head unit powers off? I believe the unit usually goes into a sleep mode rather than a complete shutdown when you turn it off. Are you sure the 5v rail goes to 0v when the HU is "off"?

I also updated my PB96MTVAPL to 20170506. I followed the instructions exactly (except I was using a USB memory stick, not an SD card) and it was very quick (<10minutes total) and all my data/apps were preserved.
[MTCD Android Head Units General] Peppergrinder:
Strange....updated it twice this morning but version number remains unchanged @ 2.47_4.
[MTCD Android Head Units General] careles:
really, pretty much... and no changelog avalaible, this version came direct from seller as is
[MTCD Android Head Units General] McIber:
Ok, It is the same mcu I Installed yesterday, but mu version shown is 2.47_2 [emoji37]

I'll try to flash it again later.

Hello

Although I have checked that the fan does not run in standby mode, I have priced the 5v on the internal connector of the USB1

cordially
[MTCD Android Head Units General] alda.cerny:
Hi, I have the same HU and I plan to add a fan too.

Do you have some photos of your HU with fan?

edit:

Can you post a link to download version 20170506?

I plan to use Malaysk ROM, but I want to try the latest official Xtrons ROM

Thank you
[MTCD Android Head Units General] DropperGK:
Hi ,

Please could you explain which DPI changer as well as how (sorry not very good with this)

I have noticed that the xtrons dab adapter is sensitive for interruptions from wifi dongle. I moved the wifi dongle from USB in glove compartment to back of my car, and voila the dab reception is far better and the dab app is more stable (had sudden crash from the dab app in the period I had the wifi dongle and dab stick near each other)
[MTCD Android Head Units General] bettuccio:
Guys, how come suddenly no longer works wifi? It connects to the cellphone but there is no data exchange. The other day, I tried to update a firmware other than MX but the flash failed. I did reset from the hole to boot and returned normal. Will he be the guilty?
[MTCD Android Head Units General] toyoneco:
Please, upload firmware

Hi, Ihave a KLD v 2.09 could you upload the firmware somewhere? I havent seen so much KLD's here (I think they're from Klyde)

Thanks!

How to buy? Thanks!
[MTCD Android Head Units General] sirleeofroy:
This is not to buy, we helped fund the purchase of a PX5 unit so that [MENTION=3590033]Malaysk[/MENTION] could make custom ROMs and improve the usability of these units.

You can find links to the first version of his Firmware in this thread:

https://xdaforums.com/android-auto/...lopment/rom-malaysk-roms-mtcd-device-t3598908

He made ROMs for the previous model and made vast improvements so it only made sense that we assist in getting him the new model, if he were to make ROMs for that too. However, I'm sure he would appreciate any donation towards his hard work, just hit the "Donate to me" button on any of Malaysk's posts.

I haven't found a new MCU version for KLD units. I was hoping my seller could provide one, no luck thus far however.
[MTCD Android Head Units General] MozzieT:
Hi all, first of all thanks so much for all this info on what i originally thought was a very niche and unknown product.

I know people asking the question of "which unit is better" is not usually very well received (understandably) however I'm really feeling quite lost with all this info.

I'm almost ready to pull the trigger on the GS varient of this unit HOWEVER

Could someone provide some comment as to whether any of the variants mentioned have found to be better quality than the others? Also. EONON (MX variant I assume? But I can't fully work it out as this unit seems to have very different apps and has a windows CE optional skin on it) has just released the 7150A. Could anyone point me in the right direction as to how to find out what unit this actually is? I have had an EONON before (px3) and it was good build quality but the main hesitation I have is that their radio app seems hideous compared to the others I have seen. Can you Install the radio app from other units onto this?

(Sorry I'm sure this is the sort of post everyone around here hates but I just don't think I can absorb any more info without some help :P )

Thanks in advance!!!

Hey TOYONECO, do you own a PX5 Octacore head unit with Marshmallow 6.0 from Klyde? if you do, can you share your Launcher apk ? it would be really appreciated . thanks.
[MTCD Android Head Units General] ikerg:
If mtcd and px5 the software is compatible between them (launchers and other apps could be compatible as well)

All px5 units have same hardware but specific can bus and physical buttons for each brand. That's why mcu software (which controls all these stuff) must be brand proprietary

In terms of quality... obviously not same quality as recognized brands (Sony/Alpine...). Even they could use same or better components...quality process should be better (some joints are badly welded....)

Perhaps are some brands that have better quality inspections than others...just see which brand are others buying and see comments.....even most brands could be the same hardware related, the difference is in the support

I have had Dasaita (hotaudio) and the support is very good

[MTCD Android Head Units General] MozzieT:
Thanks so much! Clears up a lot. Doesn't seem like many people on this forum have the Klyde PX5 so may steer clear for now. The GS (XTRON) seems to have regular updates for their MCU so will probably be a decision between that and HA.

---------- Post added at 03:00 AM ---------- Previous post was at 02:53 AM ----------

How have you found the Klyde unit so far? Specifically wifi range (wondering if it also suffers from poor quality soldering on the antenna) and overall build quality/overheating etc.
[MTCD Android Head Units General] ikerg:

Thanks will take a look. Also does anyone know whether KD MCU updates are the same as KLD?

Edit: found the info on another thread. No firm answer as to which manufacturer KD is but it's not Klyde. On a side note it is apparently comparable with Joying MCU updates.
[MTCD Android Head Units General] bettuccio:
What do you think about Witson? My unit has no physical keys and the MCU is "MX". Confirm that it's Witson? Now I'm having problems with wifi connecting but there is no data exchange! Anyone who advises which firmware solves this problem? I noticed that "Witson" updates are slower to come out.
[MTCD Android Head Units General] Mattsch:
I asked my dealer iceboxauto for the updates, had nothing in reply. I found the firmware and mcu updates through this forum !

[MTCD Android Head Units General] Floston:
I had similar problems with wifi

I repeatedly rebooted, then deleted the wifi hotspot in HU and in the phone, and only then it worked. It is said that the problem with the fact that hotspot creates a channel older than 8, if below everything is connected normally. I'll check it out today.

Anyone know if a TPMS module from ISUDAR will work on an Xtrons HU?
[MTCD Android Head Units General] bettuccio:
So is the problem in any Firmware? Then I go and try how you advised. I'll update you about this. Thanks friend.

---------- Post added at 12:26 PM ---------- Previous post was at 12:24 PM ----------

I use TPMS USB and it works fine. I had already mounted on my Android 4.4.4 unit.
[MTCD Android Head Units General] aarick:
Thanks, but I would prefer the ISUDAR one which looks the same as the xtrons one and would work on the MTC layer. Does the USB one work with the native TPMS app?

I have a bluetooth one, but unfortunately, that will not work due to the crippled bluetooth.
[MTCD Android Head Units General] bettuccio:
Isudar does not know what it is. I can only say that mine has a receiver attached to the USB and works fine. As soon as the unit is switched on, it starts automatically without danger of being killed by the system. Bluetooth TPMS do not work on these unit, I understand this.
[MTCD Android Head Units General] aarick:
Thanks for the info. Which usb tpms are u using may I ask?

The isudar one I am referring to is this one:

https://www.aliexpress.com/item/Tir...d-system-Car-DVD-Player-TPMS/32787320200.html

which looks the same as the xtrons one but a lot cheaper.
[MTCD Android Head Units General] bettuccio:
This seems like a real installation. My only need to attach the receiver to the USB. But you have to put the sensors in the tires of course ..! I can not deny that Isudar seems to be mailed to your unit.

Do not look at the blue interface. I have updated and now it is different more beautiful. On my drive is working fine.

Mirrored Fates

oh finally I found someone who made the same mistake as ME! :laugh:

not that I am happy you made it, just that I'm not alone :p

I bought from them too back in November a 5.1 PX3 for my Peugeot 308 CC, it was slower than even the slowest PX3 units and they sent me the wrong canbus so I had no steering controls, headlight detection, nothing, nada.

And when I asked them for the factory settings code (126) they sent me a LIST of wrong codes and then denied responsibility!

They were unprofessional, they were rude but they changed their ways (with me at least I guess) after a hard-written complain I bought a 6.0 PX5 from them and they sent the right canbus this time and everything works like love with ultrasonic speed. <3
[MTCD Android Head Units General] ZeligPC:
Hi! Since we have no brightness sensor, I'm trying at least to auto dim the screen brighteness at evening...

Is it normal that no app is able to change screen brightness of the unit???

I run latest KGL official firmware with root. Tried specific apps and automation apps (Macrodroid, etc.) with no luck. :confused:

Of course no problem to change it manually.
[MTCD Android Head Units General] mojo4321:
I installed this update too and mine shows 2.47_2 also. I wonder if the "2" is the Customer version under Factory settings.

This version seems to have fixed my issues with WiFi and Bluetooth. WiFi has been working perfectly since the update. Bluetooth used to disconnect periodically, but I have not noticed issues.
[MTCD Android Head Units General] Grumpycat62:
I haven't had any of the issues the other users have described regarding WiFi or Bluetooth. Build quality is good, or what I've come to expect of these chinese android headunits. Hope this helps.

[MTCD Android Head Units General] semaj4712:
Wow great thread with lots of great info. I have an xtrons unit and have had no issues, the wifi is pretty good once connected but it does take sometimes longer than expected to connect to my phone. But I am hoping to install a usb dongle with ppp so maybe that will solve the issue. Also hoping to eventually change the app loop but from what I understand thats not possible at the moment.

EDIT:

I was doing some research into the ppp setup and it seems that it is not designed to work on the android head units. I am trying to us an ATT Beam AC340U on the unit. Anybody have success with this or with using ppp widget 3 to get connection with a usb dongle?
[MTCD Android Head Units General] ZeligPC:
True, but I can't rely on that, because here in Italy is mandatory to have lights on all day and my car doesn't have daylights, so I have to leave lights on (and disable auto dimming based on lights, or the screen will be too dark in sunlight).
[MTCD Android Head Units General] phazei:
So I finally got my Xtrons PX5 unit in!

It was working pretty well, but then it had some odd issues with bluetooth. The devices kept on showing up and disappearing in the bluetooth list. Then it kind of halfway froze, then after it started moving again, the capacitive buttons stopped working and volume controls wouldn't come up from settings or status bar or anywhere. Left it all and came back a few hours later and volume worked at least.

I'd contacted their support and they provided me a link to the latest firmware and MCU. I installed it and it was the 2017-5-6 version I saw posted here, and the MCU didn't change, stayed at the same 2.43_1 that it was at when I got the unit. Since updating that, it's worked great so far. Even updated google play services and maps and installed android auto just to try it out. All seems ok, not even any echo on calls.

There's only one big issue and a couple questions left. The wifi signal is kind of weak, even with my phone right next to it or on my home wifi, just really low signal, slow slow connection. It does have a tiny little antenna that screwed into the back for wifi, maybe I need an extension for it? That's the biggest issue. GPS also is a bit slow to get going, but no big deal, I moved it further up on my dash and I think that helped.

Two questions: The "application switcher" in the status bar only shows up when on the desktop, it disappears in apps, that makes it impossible to switch applications in an app, need to always go home first which is irritating. Any solution for that?

And second, the car info icon that gives temp and fuel, it's given in Celsius and liters, any way to get that in F and us gallons?
[MTCD Android Head Units General] semaj4712:
Not sure about all of your questions, but there is a setting in torque app to change measurements to miles and gallons etc etc. Just go into settings and look around, you will find it.

Also it is a known issue that the wifi is crap on these units. In a previous post I said mine was okay but after doing a speedtest I have decided theres no way it is right. .85 MB/s Down .9 MB/s Up cant be right...If I recall correctly there is a solution which involves soldering a new antenna wire onto the wifi chip inside, is this the best-known solution?
[MTCD Android Head Units General] Mattsch:
I had to deactivate wifi security on my phone, when I make a hotspot connection, to get an acceptable wifi speed.

If i activate wpa wifi gets unstable and unusable.

The wifi on the unit i very weak, its a witson, and I cant connect to my home wifi, eventhough my phone has no problem connecting to my home wifi when i sit in the car.

I guess the wifi on these units is a really bad design.

[MTCD Android Head Units General] McIber:
That makes sense... I get same "_2" in all updates.

In my case the update did not fix the bt echo problem. I think is more related to android system than mcu, as it got resolved with the lastest android system update.
[MTCD Android Head Units General] phazei:
I'd be down for soldering, but I'm concerned about voiding the warranty. I think it had a 3 year warranty on hardware. Has anyone tried screwing on a larger antenna or an extension to I've it out from the back?
[MTCD Android Head Units General] ikerg:
You can use Tasker or lux.

Even non mtcd apps are supposed to be killed on sleep...some guys modified mtcdmanager.apk to allow Tasker not to be killed...so you could set the brightness depending on the time.

wifi issues and 4g usb stick

hello fellas,

I also have serious problems with wifi speed (same with wifi via wifi tethering or my wifi at home - mcu: KGL-Version 2.43 and malaysk firmware). USB tethering is also not working for me (is this working for anyone?). And: is there any 4g/lte usb stick known to work with this HU?

thanks in advance!

kind regards

-triagony
[MTCD Android Head Units General] ChromeSkull:
You have to turn the Bluetooth off on the phone your tethering to. You cannot use the bluetooth on the headunit reliably with any WIFI at the same time due to poor antennae soldering & setup inside the HU.

I get good wifi speed with bluetooth off on my phone, I cannot connect to office or home WIFI either, I was also tempted to re-solder the WIFI antennae cable as I have already fitted a high gain antennae which has not helped. Adding a proper second antennae cable instead of the piece of cut length wire inside the headunit that comes from factory (seriously this shouldn't be done like that for the low price of £1.50? probably less).

[MTCD Android Head Units General] TheKeymeister:
I firstly tried installing a larger antenna from an old PCI wifi card I had spare, it slightly improved things, but I could only get a signal with the unit pulled out of the dash and antenna pointing towards the house.

I then purchased a short (60cm) SMA extension cable and put the antenna further up in the dashboard. It would now connect, but the speed is terrible. I moved my router closer to the driveway but it didn't help. The highest I could get was 5KB/s. The only reliable way I have found to connect to my home wifi is to use a powerline ethernet adapter, run an extension cable to the car, and plug in a wireless access point on the passenger seat...

If you have an Xtrons unit you can access the header for the wifi antenna by removing the four screws holding the screen in place, I'm not sure how possible it is to actually solder it, but accessing it this way means you don't have to break the warranty seal. I was thinking of adding a screen mount wifi antenna as my next step (or possibly even two), unfortunately, as I have a heated windscreen, the wires in the glass prevent any signal from getting in. I'm guessing that's part of the reason I am struggling to get a signal in the first place.
[MTCD Android Head Units General] phazei:
This might be slightly off topic, but I have this thing that came with my PX3 that I returned after a month because it was too slow. Will work with the PX5 I'm sure. I forgot to include this cable in the box but never knew what it was for. I think I just realized.

[IMG="camera thing"]http://i.imgur.com/jlXWvXi.jpg[/IMG]

I'm pretty sure that's what I need since I can't plug directly into my rear power. I returned the unit, but even so, the instructions never actually clarified what it was.

The four wires with sticker tags:

red: "Reverse-In"

yellow: "Reverse+12v"

white: "Camera A+"

black: "Camera A-"

Did anyone get one of those with any of their units? I'm not quite sure how I'm supposed to wire it up, any ideas would be great! Thanks :)

Edit:

oh gosh, I can't read:

white: "Camera+"

black: "Camera-"

So that makes sense, one to the camera ground, one to the camera power. But the others aren't as clear...

Edit2:

Maybe it's a regulator and not a relay?
