Hey guys...just wanted to say there's some excellent information here, thanks all for your contributions :good:

I'm in the process of fitting an Xtrons unit to my Land Rover Freelander, I've been doing it gradually over the space of a week now.

When I first fitted it, I noticed the WiFi was very poor. I had an old PCI WiFi card and took the antenna from this, it is twice the size of the original, and it made things better, but when the unit is fitted into the dashboard I get no/poor connection. I have purchased an SMA extension to re locate the WiFi antenna to somewhere better, I am just wondering where abouts in the car other people have put their antenna in order to maximise reception? I have seen that people have soldered an additional connector, I am good with joining large electrical cables in the street but not so much soldering onto circuit boards, maybe I will revisit this later on.

The only other issue I have found so far is that the volume seems to be much quieter than the stock head unit, even with the loudness turned on in the equaliser. I have not updated rom/mcu to latest version yet, I'm waiting for SD card to arrive in the post, maybe this will solve the issue.

Try disable your phone bluetooth when using wifi.
[MTCD Android Head Units General] Ga73:
Funnily enough this worked for me on my Galaxy s6+ on O2 as I was having problems with tethering wifi if I had both wifi and Bluetooth on..... , I've upgraded to the galaxy s8+ on Vodafone and now everything works using both Bluetooth and WiFi
[MTCD Android Head Units General] ikerg:
On the factory settings menu. You have some predefined volumes for each source audio: radio, Bluetooth, music, gps....just go to music and increase it

I can confirm that Disabling Bluetooth on your phone definitely helps WiFi to work (not tried bluetooth enabled without pairing to the headunit yet).

Hi all

I have noticed two problems.

First one I posted a couple of days ago regarding the brightness of the screen. Is there any way to increase the brightness of the display? On my unit, even at maximum level, when the sun is shinning hard, sometimes isn't enought...

Second one is regarding the GPS. I have noticed that randomly, sometimes when i start the HU, there is no way to have GPS signal and sometimes, GPS signal appears instantly and strong. Any idea about what can be the problem?

My HU is an A-MEDIA MTCD with MCU v. 2.44 and PX5_6.0 UPDATE (20170324)

Thanks and regards

How do I know if the yellow B + wire is powering the car radio without dismantling?

Are there any other symptoms than Google's localization message that appears every time you start?

Thank you ;)

Hello,

I just got a px5 witson unit.

Managed rooting it with kingoroot.. Took 2 attempts with kingoroot and 3 attempts with supersu.

Does anyone know a good app or way to add a screenlock or password on startup? I would like the option of locking the device when the car goes for service, etc. Don't want someone reading my mail and/or screwing with my Google account.
[MTCD Android Head Units General] Ga73:
I'd GUESS you'd lose your radio stations each time if you've tuned them in if the constant and switched power are the wrong way around
[MTCD Android Head Units General] macandnews:
Ok, my car does not lose the radios when it's stopped, so my problem does not come from there.
[MTCD Android Head Units General] kovlaszlo:
Easily: when you start the engine (or turn the key to ACC), your headunit starts, thats not new. The decision criteria comes here: in case it starts with a cold boot (Xtrons logo / car brand logo / Android logo is shown, and takes 20 seconds), your yellow wire does not deliver the +12V when ACC is off. In case the headunit start instantly in a second, your yellow wire is connected correctly.

The "radio stations remain" approach is not working in this case.

---------- Post added at 21:00 ---------- Previous post was at 20:58 ----------

Read my other comment, that is a WRONG criteria. The radio stations are kept, even in case the unit gets no power. I swear, my unit restarts 20 times a day with cold boot :laugh:
[MTCD Android Head Units General] macandnews:
Thank you.

My car stereo starts immediately, so the yellow wire is well powered.

My problem is elsewhere, I do not know what to do to make this message no longer appear at boot!

I am the only one with this problem after I upgrade?
[MTCD Android Head Units General] kovlaszlo:
I think your issue is software related. When it appeared first time, you were right after a FW update, and if I am not mistaken (maybe I am), someone else also claimed for this, maybe in this thread, maybe in Xtrons forum, I am not sure
[MTCD Android Head Units General] macandnews:
Yes, I have this problem since the firmware update.

I tried reinstalling it several times by erasing the data and cache, but I still have the problem.

Yesterday I tried to install the version posted by alautobot, but it does not change anything.

Whatever choice I make in the location setting, the car radio always returns to: activated and high precision.
[MTCD Android Head Units General] TheKeymeister:
That worked great...thank you :good:
[MTCD Android Head Units General] halloj:
First, I've it on my bench. It's powered by a standard 12V 3A power supply. Second, standard colors for B+ is yellow and red for acc.

As I suggested to the other guy I saw the same symptoms like he had when pulling B+. It came out that he had another situation.
[MTCD Android Head Units General] alda.cerny:
hi users with PX5,

have you noticed problems with overheating or is cooling sufficient?

Have you measured the temperature during the load?

Thanks for answers
[MTCD Android Head Units General] trap63:
I get no echo using a 9100MK microphone of Parrott and adapter for 3,5 jack, I run on Samsung S7 Edge with Nougat, try to reduce volume in factory settings under "BT" range.

set passkey on unit to "1234" and you can pair their ODB, might be possibile after several times to pair other devices i.g. ODB Link LX of Scantool. They modified standard BT API for selling their products. We hope that [MENTION=3590033]Malaysk[/MENTION] will solve the issue.

All the unit is on trouble with permissions, I rooted the unit and tried to fix permission (Mmallow fixer) and issue still lives asking me to grant access. Same as above, we wait

See #post1 for MCU upgrade to 2.43.1

Try to solve reducing volume under factory settings as explained.

Hi,

I have MTCD_KGL_V2.21_5 (Feb 16 2017)

Can I update this to V2.43_2 using menu item MCU Update?

Can I keep the existing FW or I have to update the FW as well?

Is V2.43_2 the latest available MCU update for KGL type?

What is improved/resolved in this version?

Many thanks!

Hi,

I have 2014 Ford S-Max and I recently bought XTrons PB76FSFAP-B HU. Everything works well, except of echo during phone calls and low quality of BT A2DP streamings. Do you have any idea who to solve those issues... Xtrons support is useless, except of sending time to time new SW updates. Anyway SW seems to be not even developed by Xtrons, but rather OEM HU producer.

Another question I have is related to parking sensors - How to enable GS boxes to work (audio & visual) with CANBUS PDC sensors???

I have a factory build-in sensors. They used to beep through original radio speakers, but after replacing radio with Xtrons, they stopped to work. After installation of some special ford mini speakers connected to ford PDC module and reconfiguration of the on-board car computer, I restored the beep functionality. Question is if you know if there is any way to enable visualisation of parking sensors on the android HU.

I have searched an internet and found that Eonon, which seems to be another brand for the same OEM HUs, has radios with such parking sensor visualisation functionality - https://www.eonon.com/Android-Car-GPS/Vehicle-Specific-GPS/GA6162F.html

Is there any special software for that? other Canbus box or the radios of Eonon are canbus enabled, unlike to xtrons.

Thx,

Karol
[MTCD Android Head Units General] Arjen-S:
I have the same problem, it is a firmware problem in the KGL update.

My unit bought with a previous KGL version works fine.

Used Dasaita / hotaudio firmware after that to solve Google maps problems, that firmware works fine also, but I do not like the User Interface.

So I think we have to wait for an update or use other firmware.

Thats the fun with Android, always something not working :)
[MTCD Android Head Units General] eter711:
damn it, firmware update wipes everything :/

i did not check the wipe box.
[MTCD Android Head Units General] timo-n:
I have the Echo Problem also without the external Mic so it only can be a Problem with the Firmware.

Sometimes the Bluetooth Connection disconects completely during a call and reconnects after 5 or 10 seconds...

Each manufacturer has different launchers ... but same ROm is used. Perhaps it is related with the launcher itself?

[MTCD Android Head Units General] Arjen-S:
Yes, that's possible, problem is the same.

If you load the firmware the problem is there.

You can also choose an other laucher but how do you do that?

After loading new firmware you hope everything will be OK.

You do not want to tweak anything so the story is the same.

We need an update to solve the problem.

I bought the app a month ago, it's an awesome app. you can try before buying
[MTCD Android Head Units General] kovlaszlo:
This 5-10 seconds break in the connection I have as well, but i think it is not related to the HU (at least in my case), because i had the same problem with the Parrot Asteroid. I have a Huawei P8 lite. The problem comes after a longer time of discussion (10 minutes maybe)

---------- Post added at 07:21 ---------- Previous post was at 07:02 ----------

Sorry, i do not understand this, and i never will.

First of all, regarding being free: nothing on earth is for free. You have to pay the price always: sometimes not with money. Sometimes in money, but not immediately - but you pay. In case of an app, you may get the commercials. If no commercials, maybe you pay with your data, and the commercials come later. You may steal the app, but if everyone would do it, one day noone would develop apps any more... So those who do this, are stealing from other users, and - sorry, if i hurt anyone - they are petty criminals: most apps cost less, than 6 EUR / USD. This car launcher is e.g. 3 EUR...

second: security. Hey, didn't you see? We are using an android system, which was developped in China, by noone knows, whom, was installed on a hw by someone else, who can also make his "adjustments", and your data may be a value for both of them. And the adjustments they made are so extensive and deep, that they could hide many things inside... You should not be worried about security, when you install apps :)

Thank you!

I have downloaded the update.img file from the link in the 1st post (4pda). "PX5_6.0_14.04.2017.7z"

How do I actually do the update? I'm a bit confused about this.

My current installation is rooted.
[MTCD Android Head Units General] Grumpycat62:
I'm running MTCD_KLD_V2.35_1, and my seller sent me an update file, however it appears older than the ones you guys have posted. If anyone knows if I can flash the update.img from this forum it would be greatly appreciated.
[MTCD Android Head Units General] sirleeofroy:
I have the Xtrons unit so I just place the .img file at the root of the micro SD and pop it into the GPS card slot, the system detects the update image and does the rest for you.

Your current system will be wiped so you'll need to root and load your apps back on after the update.

:good:

---------- Post added at 04:04 PM ---------- Previous post was at 04:00 PM ----------

For sure, you'll be able to use the update.img but make sure that if you want to update your mcu, that you get the right one for your machine.
[MTCD Android Head Units General] corpcd:
I have my unit back from support (xtrons), or better said, a new unit (different s/n). It does not have physical buttons, are they backlighted? I dont remember if the other unit had it, or if you can set the color of the buttons.

Edit: Solved, the illumination wire was not pluged in correctly. Now it works. The setting to change the color is called "Element"... weird.

Also, the contrast is different from the first one, this one has more bright, even at lower level.

Finally, i can´t get to see certain videos (for example, from the youtube app), from the navigator, m.youtube.com works fine (i can see the videos there, but not from the app). Is it related to flv format, maybe? I've tried MXPlayer and VLCPlayer also, no suceed.

Edit: Solved, i had the "see videos while driving" option disabled.
[MTCD Android Head Units General] eter711:
you must allow video while driving in the settings
[MTCD Android Head Units General] corpcd:
Yes, that's it!!! Thank you, in the old unit, it was enabled by default.

Another question: where is the option to disable the rear camera. I dont have any rear camera installed but when i put the reverse gear, the music stops and the screen goes black. I bet there is an option to disable that.

[MTCD Android Head Units General] Floston:
Unzip to the root of the USB drive, insert it into the device - the system will automatically detect and install the update file and prompt you to update. Select the checkbox for "wipe data" (all previously installed applications and user files are deleted)

The device will reboot and installation of the update will begin - installation may take about 15 minutes (on the screen the logo will rotate all the time, Then start optimizing applications and most likely there will be several reboots) !!! Do not touch or turn off the head unit until you see the main application window!
[MTCD Android Head Units General] kovlaszlo:
There is no option for this in the software. Unplug the reverse camare signal cable! In my case it was a blue wire, separated from all the others (not plugged into ISO) - the label was "BACK-CAR"
[MTCD Android Head Units General] ZeligPC:
Well, there IS an option for that...

In "factory settings" (enter with password 126), one of the last options in the last menu ("other") is called "prohibit reverse". Set it to "disable". ;)
[MTCD Android Head Units General] user602:
My HU has an option under Factory Settings (accessible with password 126) called "prohibit reversing," or something similarly nonsensical (I don't remember exactly, I'm away from my car for a couple of days). Change the option from "enabled" to "disabled" and your music will continue to play when in reverse.
[MTCD Android Head Units General] kovlaszlo:
After two different persons telling the same I have to say, I must have been wrong :o
[MTCD Android Head Units General] ikerg:
Prohibit reverse is for enable or disable the reverse display once reverse is triggered

There is an option on settings (i dont remember which) for let music to be above the reverse image (avoiding interrupt music when in reverse)

I remember on rk3188 that during boot you could get reverse image from camera but I dont find that in the new units.

Or this feature has been disabled as it is supposed to not cold boot (my Intel sofia mtcd still cold random reboot)

I dont have rear camera, so i dint pluged that wire. In fact I only have the wiring harness on (I'm testing the unit at home using a PC PSU).

Thanks, I'll check it.
[MTCD Android Head Units General] msb111:
Hi,

Did this. The update was detected and it cycled through.. Reboot.. Installing... Erasing.. Optimizing, etc.

But the version number under About Machine still shows the old one - MTCD_MX_V2.40_1 MAR 20 2017.

Edit: Figured it.. The Build Number changed.

There was also a DMCU file - dmcu_MX_2.44d_14.04.2017.7z

Do I need to flash that as well?
[MTCD Android Head Units General] kovlaszlo:
In this case your issue is not clear to me. Your first related post was this:

Sorry for the joke, but I guess you had no reverse on the PC where the PSU is coming from :D

Let me explain. The standard solution is the following: in case you have a rear camera in your car, you should attach the cable I was explaining about to +12V coming from your reverse light. This requires taking a wire all across your car from the backlight to the HU - there may be other tricky ways depending from your car, so this is an example, but let's make it simple. It is a different story, if you have a CANbus box, and/or a factory fitted reverse camera in your car: in that case the signal is already there, and you can attach it to the HU. BUT: without connecting this cable (BACK-CAR), the HU doesn't know, if it should switch to reverse camera, so you should have no problem, when you install the HU in car, and therefore there is no need to change the SW setting.

EDIT: I was still thinking about what you were explaining, especially that you power the unit from a PSU. Maybe you have a different problem that you/we supposed! Please let me know the following: when the black screen comes and the sound goes, do you see a yellow triangle with an exclamation mark in the center of the screen?
[MTCD Android Head Units General] ZeligPC:
True. I don't know exactly how it's "traslated" in english (I have my unit set on italian language), but it should be something like "extention settings". There you have "reverse sound" and you can set the sound attenuation level (you can just lower the volume or, if you set it to 0, let the music play as before).
[MTCD Android Head Units General] Alcaone:

Hi,

I have a unit from China, no brand but the MCU version says GS, is it safe to apply the GS rom and mcu update?
[MTCD Android Head Units General] ChromeSkull:
Hello fellow E46er That does look like an Xtrons Unit and as its an MTCD GS it's the same as mine so yes it will work. Seriously use the 20170407 update. It's fixed my stuttery maps audio.

BTW ignore the 1.5ghz in the CPU speed in that menu. It's max clock is locked at 1.2ghz even with a root and "SetCpu" app cant increase it lol.

Not tried any other methods of increasing the speed but it seems to not be required.
[MTCD Android Head Units General] samer88:
Thanks a lot m8! Will apply the update today :)
[MTCD Android Head Units General] corpcd:
Yes, when I installed in my car I noticed that everytime I put the reverse gear, the screen went black with a orange or yellow triangle and an exclamation. I do not have a rear camera installed, so the wire of the rear camera is not pluged.

When I wrote the text you quoted I meant that right now, the unit is at home, because I send it to support and got a new one that I am configuring and installing things. I power the unit at home using a PC PSU, something like this:

[IMG="PCPSU"]http://www.meanwelldirect.co.uk/public/ranges/images/1636/yp-450A-AA_300.jpg[/IMG]

You only need to get a 12v and GND from it and attach to the wiring harness (12v to ACC and B+ and GND to GND) and it powers on.

Obviously, I cant check if the solution provided for the reverse camera issue works because I have not installed in my car to put the reverse gear.
[MTCD Android Head Units General] kovlaszlo:
In general, regarding the PC PSU: I have a built complete box based on it. The box is integrating the PSU itself, four speakers, some switches which can simulate ACC, illumination and reverse :), and a car stereo ISO cable connected to all of these components.

OK, now it is clear now where you are. I do not want to make a short story long (although I am already making :) ): in case you can solve it via SW settings, should be sufficient. Just one last question, for my personal interest: do you have a car-specific unit with car-specific harness? I guess you do.
