I had a similar problem with an new PX3 RK3188 (2GB Android 7.1) and my solution might help you out. After reading the threads here and how the issue seems to be resolved when there's no demand on the system (no apps running, less demand on processor, etc.), there's one thing you might want to try - clean-up the incoming power. When there's more demand on the power, there's more chance for noise to come in and throw things off. If there's too much noise on the ground, or incoming 12v power, that noise can cause a lot of problems.

When I first installed my (new) PX3, I had issues with wavy lines in my backup and DVR cameras, a slight, barely noticeable whine when FM was playing, and the mic didn't work at all - people just said I sounded all garbled. I had installed the newer PX3 in place of an older RK3188 (1GB Android 5.1) system, and that one had zero noise issues and the mic worked great.

I went ahead and installed a noise filter directly on the incoming power behind the stereo. All my problems went away. Cameras are clear, the mic works, and no stereo noise. At the same time, I also added an external mic, but I never opened up or modded the system. I've had a few conversations with people in the car and no one has complained about the call quality.

One thing I noticed on my PX3 was that the power wires (mine is specific to VW) were all made from steel (or aluminum), when the wires from the previous system were all copper. I'm not sure if this is the cause of the problem, but it can't be good. It's just a lot cheaper.

Hope this helps anyone - and Thanks to typos1 for sending me over here from another forum. :)

My button colour mapping app doesn't exist anymore under settings. Panel buttons are now dark (no LED light).

Is that an mcu issue or android issue? I'm guessing mcu so I'll need to find a more compatible one.

I am prettty sure heat has nothing to do with it. Today it happened to me - I was driving for less than 5 minutes this morning (outside temp was 12 deg celcius) and the sound from Pocket Casts went silent, and the unit went black - but still with backlight, and still light in the leds for volume and power. I reset the device with a toothpick, and the screen looked like it disintegrated for 3 seconds, before resetting and booting back up - after that there where no problems. I listened to music for the remainder of my 20 minute drive, without any hickups

This is interesting to read as I've got an a3 with a px5 unit that has a few glitches so I'd be interested in trying this.

Where exactly did you put the filter? I'm quite new to this forum aswell so just getting my head around everything to do with these units. I'm guessing you put the filter somewhere in the loom that came with the unit that plugs into the quadlock connector?

Hi..

Is it possible to find a 4G / LTE USB dongle, that works on MX Headunit?

I have E3131 3G now.. And it works.. But I would love more speed.

I have a E3372h 4G LTE dongle that only works with ppp widget.

And then I dont get fast speed.. Only a little more speed than 3G
[MTCD Android Head Units General] markmorto:
I used a noise filter like this that I bought at my local auto parts store: http://www.ebay.com/itm/Universal-12V-Car-SUV-Noise-Audio-Filter-12V-DC-Car-Stereo-Installation-Engine-/253091257513?hash=item3aed6a1ca9:g:-0MAAOSwr~lYrVTe&vxp=mtr

The filter has three wires:

1 for input from the car's 12v power

1 for output to the car stereo 12v power input

1 for ground

There are other filter options, some smaller than the one I used, but it did work well.

I installed it directly behind the stereo, and had to squeeze it in on my VW. Luckily there was a space behind and under the stereo for it to fit.

As for the wiring, I cut the ACC (alternator power) 12v line about 4-inches from where it goes into the back connector on the stereo, and put the filter wires between it. I just tapped into the ground wire - didn't need to cut it.

---------- Post added at 08:56 AM ---------- Previous post was at 08:54 AM ----------

You guessed right - I actually cut the wire between the car's connector (I have a VW with a special connector) and the connector on the back of the stereo.

Hi..

After a 4 hour trip in high summer temperatures i measured with an industrial laser temp gun 83c on the cpu cover..

So i desided to do this..

I used this size to cover only the cpu and leave as many holes empty on the som cover to let the rest circuits breath like before.

I dont know if there is a real benefit on performance since i dont know if the cpu was thermal throttling..

But it feels much better that i will be sure that this thing inside there is not burning like lava and reduces its already short cheap chineese life..

I used thermal glue and a quiet 12v small fan.

Connected on the amp trigger (12v) and ground on the board screw near right.

It would be better without the cd rom ( better clearance and air circulation..) but i desided not to go this way and installed it.

No clearance issue with the cd-rom ribbon also.

The measures i took show there is no need of an external fan as with this setup seems i have lowered about 20c on cpu temps comparing before and after.

Unfortunately there is no data to post as there is no app to monitor px5 temps accurately.
[MTCD Android Head Units General] typos1:
Yes, this is a good idea and has been done before on RK3188/PX3 MTCB,C & D untis, indeed Klyde MTCB/C units used to have a fan mounted on the back of the unit and even their MTCD units seem to have an unused connector for it - you could have used it on yours -its the white connector on the motherboard, which looks like its a KLDE one.

There is also some factory thermal throttling on RK3188/PX3 units, not sure a bout the RK3368/PX5 ones, theres a thread in the MTCD forum about it. AFAIK like the RK3188?PX3 cpus, the RK3368/PX5 ones dont have a thermal sensor so its not possible to monitor the temps.
[MTCD Android Head Units General] lefterisa3:
Motherboard had 3 2pin connectors.

One near left of the som

One up left near the plugs and another 3pin uper midle.

Tryied all of them got no power..

Maybe they are not software enabled
[MTCD Android Head Units General] typos1:
Hmm, strange they bothered adding them at all then, I d have thought theyd have been hardwired anyway.

You can try the app "kerneladiutor" to see if theres any throttling.

Xtrons PB76ATTARP

Hi i was just given the latest firmware by Xtrons for the Audi TT Mk2, PB76ATTARP Head Unit if anyone is interested, It has a new interface and various improvements seems much more fluent and the interface is much improved.......... It includes GS MCU 2.56 And PX5_6.0 20170721.

I am not allowed to post outside links due to post count so PM me for link.

Hope this is of use to someone. :D
[MTCD Android Head Units General] typos1:

Its not "by Xtrons" though, theyre just retailers, its by MTC, the developer, for GS, the manufacturer.
[MTCD Android Head Units General] ThiBor1:
Yes i am aware who develops and who retails etc but if you read my post i merely stated who gave it to me, and it was given to me "by Xtrons".

You're still better off with the Malaysk ROM though IMO.
[MTCD Android Head Units General] ikerg:
All the roms are the same....normally some manufacturers ask developers for some particular esthetic changes to customize it....but if any improvement is included due to some bug removing or something relevant developers include them for all manufacturers (as they present common hardware and, therefore, same issues)

[MTCD Android Head Units General] markmorto:
Even with the noise filter installed, there are still noise problems under load. I made this video https://youtu.be/1xBegb27S8k to show how the backup camera gets distorted when the stereo is cranking - you can see the waves flash when the bass kicks in.

I ordered a better power filter, but these units do not have adequate power supplies.

[MTCD Android Head Units General] typos1:
I dont think its the units, its something to do with the RK3368/PX5 SoM - I ve not heard of any similar problems with other units.

The rear usb ports on MTCB/C devices only have 3.3.v (which can be easily modified), but thats really a different problem and doesnt affect the whole device.
[MTCD Android Head Units General] lefterisa3:
It is the som..

With the unit disasembled if you loose the right screw of the som you will hear the noise geting 200%louder!

Under the metalic plate of the som in that position is a lip that acts like a rfi shield for a cirquit on the right of the som.

Its not sealed 100% and if you look closely it has gaps as the metalic plate is not totaly flat on it..

[MTCD Android Head Units General] markmorto:
That's exactly how I first found out that my power supply was noisy - I tried to put a filter on the camera, but it didn't help, mainly because the camera gets power from the stereo, so the noisy stereo power is causing the waves and noise on the camera under load. When the stereo isn't really loud, the camera image is mostly clean.

---------- Post added at 10:30 AM ---------- Previous post was at 10:20 AM ----------

So it sounds like the fix is to add some RF shielding tape to the leaky metal RF shield then?
[MTCD Android Head Units General] DanB0y:
Without any speakers connected to the headunit and volume high, does it still waves and noise on the camera ?
[MTCD Android Head Units General] typos1:
Sure does.
[MTCD Android Head Units General] :
Can you please repost link. This one does not work. Thanks
[MTCD Android Head Units General] :
No easy way to test that, as the power connection includes the speaker connections. I see where you're going, but if you remove the speakers, and the load, the current draw on the unit would be a lot less.
[MTCD Android Head Units General] DanB0y:
Yes exactly thats my point :)

If you dont have power draw from the speakers but still have the same problem, maybe the problem is'nt with the power supply.
[MTCD Android Head Units General] markmorto:
At this point, I think the previous posts about the SOM causing noise are the root of my problem. The head unit I had before, an Android Xtrons (HH, 5.1, 1GB) had zero problems with the exact same car/power, and without an inline filter. Before that I had a Joying WinCE system that was probably the best manufactured so far. Zero noise, and rock solid camera images, microphone, etc. It just worked. I upgraded to get 2GB performance more than anything else.

My in-line power filter helped make things a little better, but it was more of a bandaid than anything else. I plan to take it apart and see if some creative use of some RF tape will make everything better.

My new problem, after trying a new filter yesterday, is that my radio (not SD music/Pandora, etc. - it all plays great at any volume) now buffers music when the volume goes above 50%. It's stuttering like crazy, and I think I caused the problem myself. With power removed, when I pulled the first wire of my (capacative) filter, it touched the stereo case and discharged with a spark. After changing the filter out, and restarting the system, everything seemed to be OK, until I tried the radio. It stuttered at high volume - anything over 50%. I put the old filter back in, and it did the same thing. So, whatever radio preamp they have in these things is probably fried to some extent.

Do they make replacement radio modules for these, or would I need a new unit altogether?
[MTCD Android Head Units General] typos1:
I think you should try the RF filter for the SoM.

"HH" ?? You mean that was the manufacturer ? ie its MCU was "MTCD HH" ?
[MTCD Android Head Units General] markmorto:
Yes - it was an Xtrons.
[MTCD Android Head Units General] typos1:
No it wasnt an Xtrons, there are no Xtrons units, Xtrons are sellers they buy from manufacturers, stick their badge on and sell on, on XDA we identify units by the manufactuere, ie the letters after "MTCD". Are you saying the letters after "MTCD" were "HH" ? If so this is a new manufacturer.

[MTCD Android Head Units General] typos1:
To identify your unit we need to see what the MCU version is, Erisin are sellers, not manufacturers, they sell lots of different units from different manufacturers.

Again we need the MCU type and the car type also and you have to have a car with CAN Bus.

CAN Bus support can depends on what make and model of car you have, what level of trim (for instance non electronic climate control does not normally appear on the head unit) and whether the built in CAN Bus apps support every function of the CAN Bus system on your car.

Enviado desde mi D6603 mediante Tapatalk
[MTCD Android Head Units General] typos1:
ANY car with CAN Bus and electronic climate control COULD display the climate settings on screen because the body computer will intercept ALL signals and the CAN Bus decoder will know about it . . . but ONLY if MTC has included software for that function in the pre-installed CAN Bus app (and its associated apps, "Car Settings", "Vehicle" etc).

But support for different cars is patchy at best, its most likely to work on VW group cars, less so on others, this is down to MTC.
[MTCD Android Head Units General] ikerg:
That's the point....

1) the can bus box shall be programmed to intercept that signals

2) mtcd software shall be prepared.

What I said is that there is a lack of information about the product capabilities....and we think that specific model will be Interacting in the same manner as VW or other brand that we saw once lot of information and interaction with the car (it should be) but for others brands...the interaction is minimum....it depends on the brand model but the canbus could be limited to only give you signals for reverse camera and swc

[MTCD Android Head Units General] typos1:
As I ve said so many times, there are no Erisin units, they are a seller only, they sell units from lots of different manufacturers. To find out what unit you have got to settings/about device, the entry in the MCU field will tell you what unit you have and the manufacturer.

It could be on the wrong setting in factory settings, have you checked ?

It depends what module you have, all the ones I ve seen have multiple pins connecting them to the board which your ll need to de solder, your ll ahve to take your unit apart and have a look.
