Last month, I found this this Android 5.1.1 Headunit on Aliexpress for $227 shipped. I decided that the price was low enough to take the risk and purchased. The vendor's store is TONGTAI HONGKONG INDUSTRIAL CO.,LTD I am not endorsing the vendor, I didn't need them for any support yet, but I assume people will ask due to price.
Today was the first nice day since I got it, so I did the install this morning. I'm not going to recreate the install here, as there are already many for the Eonon, Dynavin, Avin, and others. This is just like those. I will note where I came across anything I wasn't expecting below.
A couple of points, I did not install a backup camera. My E46 is a Cabrio, and visibility is fine, I just don't think the benefits are there for me. Additionally, DVD is not important so I didn't check that out. I do want a working Radio, Bluetooth Calling and streaming and Navigation. This unit is doing all of that.
Opened Box
Retail box - I've seen other units that have the identical packaging
As Packed
Parts laid out
Parts laid out 2 - Note- connectors for the early and late radio's and early and late antennas. My car is one of the 2006 330's, and one of the last off the line.
Closer pic of unit - These look exactly like every other unit on the market.
Navigation SD card included - I read a lot of different solutions on where to put the GPS antenna. I was going to put it in the spot behind the instrument cluster, but BMW already had a factory installed antenna there. I guess by 2006, it was cheaper to put the antennas in all cars (like the factory Bluetooth). I used the metal cross bar above the radio. The antenna has a magnet on the base and i just sat it on top, it won't move. Reception, for me, is fine.
Back of unit. Cleaner than many - Note On many of these units the can-bus plugs into the back. I have been told that that makes fit difficult because of the amount of wires back there. The can-bus came off a pigtail on the mail unit and was easily tucked out of the way.
Another pic of the back of the unit - Note the white input plug under the antenna in. Those were for the RCA connectors for pre-amps. It wasn't needed it this install, the factory harness took care of everything, left those pigtails out.
Top with wiring diagram - All I did was remove the screws and plug it in, I didn't have to refer to any wiring. I will say I had trouble getting the adapter to line up with the factory plug. I almost broke the harness side. Not sure why it was so hard to align, but eventually it did.
Climate controls moved to the lower spot -Here are the climate controls moved into the lower section. I got a used navigation bracket off eBay for $20. The lighter clips were broken on one side, but not off. I had to use a cable tie to "lock" it in. If I had caught that before install, I would have swapped the lighter for a USB
Unit Installed
Radio Screen
Bluetooth Phone Screen
System Screen - Originally this was on a July MCU release, when I went into the about screen, it offered an update. An old ROM was on the Nav Card, and I overwrote the newer ROM with the older version. I sent the vendor a message to see if they can send me the link to the newer one. That said, I am not having an issue with this one.
Here is a walkthrough of it live. The video stops when I use bluetooth, not because of the headunit, but my phone stopped recording when making a call.
https://youtu.be/Vtv2tJte5oQ
All said and done I am very happy with this unit based after installation. I have been reading many people who have issues, so maybe I got a "good" one, or maybe issues are yet to come. If you have any questions, fire away.
Well it was great for 2 hours. Screen is unresponsive now. Any suggestions...

Sorry I cannot help with the unresponsive screen, but I have a question
For the few hours you enjoyed it, how was the display in direct sunlight?

It was ok, this morning driving to work their was a good bit of glare, but still very readable. I will try it with the top down and see what it can take would assume that would wash it out.
Pretty sure a matte screen protector would solve any issues with glare. Something like this should do for my screen
http://www.staples.com/Iessentials-...ctor-For-7-inch-8-inch-Tablets/product_210060
I have a car with a targa roof.. I tried a matte protector with my newsmy NU3001 and it did not help. I really like the idea of the Touch screen UI but I think I am out of luck for seeing it on the screen. I have a MTCD unit too but have not tried it yet.

Have you tried to reflash the unit? Factory ROM for you unit should be available somewhere on the forum. It looks like it lost touch calibration.

I thought that was exactly what happened. I reflashed both ROM and DMCU, but didn't help. The vendor sent my video over to his engineer and they are going to get back with me today. I am thinking its a physically problem with the screen like something worked its way loose or the heat of the day effected it.
System Re-Flash from recovery mode.
I just went into recovery mode and did a full reflash again hoping it gives some information about what is happening. I videoed it, and it will (in about an hour) be available here. https://youtu.be/9Q70WxcMzzg Warning beginning to end its 8:21. May be of use to someone trying to understand how to get into recovery mode and reflash
I went ahead and typed the messages on the screen after selecting "Update system/mcu image from sdcard and clear all" all the text that followed is below. I see an error came up in parsing the backup, not sure if that effects the loading or not, it seems to be running the same

The vendor got with his engineer and is pretty sure it is the touch screen itself that is the issue, not the software (I was thinking the same thing). Their guess is the cable has somehow worked loose and want me to open the unit and check the cable connections. He sent me a photo of what to look for (below). Any recommendations/warnings before taking this thing apart tonight?
Thanks, this thread may be too much me, but if someone else is having the same issues, I want to make sure there is somewhere they can look for troubleshooting and hopefully an eventual solution.
BTW, so far vendor communication has been really good.
Hi, have you been able to fix it? I'm thinking of getting the exact same head unit (as opposed to universal one with all the extras I would need, like fascia, cage, harness)

Mailed I back, they received today and are returning a new unit. Will update when it arrives

I got an update from the vendor, and the issue was a touchscreen cable worked loose. Absolutely a problem with the assembly in China, and probably something I could have fixed if I was skilled in electronic repair. My new unit is on the way here.

Are there any benefits buying a eonon unit compared to this one? Are they from the same factory you think? The new eonon has Bluetooth 4 compared to others? How can that be if they are all from the same manufacturer?
I suspect they all come from same factory, Eonon, Joying or no brand - the only difference seems to be the software.
I'm quite happy with my "generic" unit, so far so good. But didn't test bluetooth more than just paired with my phone, no calls yet or any obd2 readers used.
My main use is navigation and that seems fine, but my phone seems to be getting a bit more accurate gps lock according to gps test apps.
PattonD, have you tried a Bluetooth call? How was it? Did you use the internal mic or an external?
One of the most important features for me...
The unit you bought is very interesting.
I got the unit. I tried the unit at home. Internal mic seems fine.
However, how is the reverse camera installed? Is reverse signal coming from the canbus system or must i cut the brown cable (cable 8, back car cable) and connect it to the reverse lights?
it is the plug
I'm not really sure what you mean mate
so planning to catch some of the commons issues I seen over the forums, and want to see where people managed to fix issues, and I will add my own from experience, I had read through the forums, and tried many of the suggestions:
this on Erisin KGL PX5 Unit for VW.
I had tried factory MCU firmware, Factory andriod system
then
latest MCU firmware Malaysk andriod system.
and while the unit improved. this did not have any effect on the following problems:
NOISE ISSUE
1- when unit isoff, no sound at all from speakers
2- when unit is on, but muted very low volume constant tune hissing sound.
3- slightly louder volume constant tune hissing sound when the unit is NOT muted (does not go up as volume in increased)
4- data like noise, (like old computer onboard audio, noise is relevant to how much processing is done), this does not go up as volume is increased
a) I had looked into lowering the aux input gain from factory menu, thinking it might be aux in being not connected causing some of the above
b) tried removing every single cable (apart from the harness that is powering the unit)
c) what I will try next, is to see if I can provide cleaner power to the unit, or improve the ground, I am not electrical engineer, so some advice is needed.
-----------------------------------------
"Here Maps" Audio skips milliseconds of speech.
so instead of saying "take the first exit at the next roundabout", it sounds like "take the fist exi at the nex rou bout"
I had tried downloading other voices, but the the problem persist.
I really have no idea why this is happening but will be nice to know how to solve it.
--------------------------------------------
dreaded wifi issue:
unit wifi is really bad although I literally parked next to the router, at my house, and there is only a window rather than a wall i between.
only remedy so far is to improve line of sight, however I read that improving the grounding, or getting better wifi antenna might solve the problem. so will give this a go later.
----------------------------------------------
Radio performance was appalling out of the box. so I purchased fakra radio adapter (powered)
this improve performance significantly, and now it picks up most of the radio channels.
still the radio is not as good as stock radio that came with the car.
as most channels have a bit of crackling sound, very few sound perfect.
----------------------------------------------
the screen is very reflective and barely visible in daylight, (I have light color leather seats) which makes the screen even worse.
so I am thinking of buying anti gloss screen filter.
I would think it will wash out the colors a bit, but I am willing to do that in order to see the screen properly.
as of night time, even when lowering brightness to min, its still bright, so I am thinking of getting something like Lux or automatic adjustment based on time (since the unit does not have ambient sensor)
------------------------------
2 months ago I had also a KGL / Erisin radio for VW with sound problems. You always heard a noise from the speakers. The Boise came from the AMP chip. Then i had a Ownice C500 that also Bad noise from the speakers. Now i have a Xtrons PX5 Unit and there is no noise. Additionally i have made an upgrade from TDA 7388 to Pioneer PA2030A, now the sound is perfect.
how did you upgrade the MOSFET?
are they pin compatible and you can desolder the old one and replace it with the new one?

Exactly. You can buy the AMP on eBay.
I've not audio issues, but for me radio reception is not so good, in particular the AF option works very bad!
Wifi performances are intermittent (I've a 4g wifi dongle; the signal comes and goes...) but when it goes, it downloads at full speed.
Screen is very reflective but lights are ok for me.
I have some problem with google maps app: it locks and I've to restart it 2 o 3 times... I don't know if it depends on the app or on the system.

I have the Erisin 6405V in my VW Golf mk5. All seems to be running fine, haven't noticed the wifi issues really as I mainly use a USB 3G Dongle I have connected.
For your navigation audio, goto Settings > Navigation Settings and change audio mode from switching to fixed(?) (basically the other option, I can't remember off the top of my head) I found this fixed my issue in google maps.
Also highly suggest to do all google play updates (maps/google app/play services) that's improved the stability of alot of the apps I use on my headunit.
I'm (I think) running their KGL_PX5_6.0(20170502) that erisin sent me to fix my bluetooth echo.
My -only- issue I'm finding. I had a previous headunit's I had tried and sent back for various reasons (xtrons and eonon) they detected my car doors open etc correctly but the erisin one doesnt seem to. Not that this is a problem, just wondering where the issue could be as the CanBus settings seem to be correct.
The hissing you hear is caused by the Wi-Fi. Turn off Wi-Fi and you will see that the noise is gone
turning off the wifi does not fix the issue.
as for mixing vs fixed mode in navigation audio, that did not make a difference.
I will open the unit soon to upgrade the amp, and maybe dampen the noise with a help with an electrical engineer

I also have the noise, this is my second head unit, I had to return the old one due to issues with the buttons... Is swapping the mosfets very complicated? I am comfortable with soldering irons, have used it for other works... Do you have any pictures of the work done?
Thanks

Here is the link: https://workupload.com/archive/49a8wjT
I contacted them via email.
I had took my unit to hardware lab, and powered it, and connected it to oscliscope.
it seems that there is 25khz noise on the speaker output all the time.
I had tested also pre amp output, and that have some noise too. so my guess is that good amp would cut off those high frequencies, and thats why it sounds better.
I will try to use ferrite cores, and see if it improve the situation, although I think it will not be able to cut low frequencies, but it never hurts to try espacilly this means no need to open the unit. I will report back later
j0nnymoe, can you tell us the MCU version for your unit after the update. thanks
Did you try 2.47 MCU? That's the latest for MTCD KGL PX3/PX5.
I have experienced noise issue #4 when I am using WiFi hotspot from my phone and phone is next to the unit.

This noise is so annoying, it makes me miss my OEM head unit, my car has an OEM Bose sound system with an amplifier under the seat and a subwoofer in the spare wheel, I don't know if this might be the issue for me, the subwoofer and all 8 speakers certainly work, as soon as I mute the head unit, the noise is gone, as soon as I step it up to Vol 1, I xan hear the noise, when the music or radio is playing, I can't really hear it but if the volume is up and it comes to the end of the song, I can hear it and it's bugging me... I don't know of replacing the AMP chip with a Pioneer chip (As mentioned before) would be the ultimate solution to get rid of that noise...
The other problem I am facing is the brightness of the screen in daylight, I have a Dasaita V600 (Specific to my 2012 Mazda3), I barely can see anything during the daytime, the brightness is cranked up to the max, are there any other settings to play around with? Contrast maybe etc...

opened the unit today, nothing obvoius of whats wrong.
I noticed that the wifi antenna connected to realteck chip that claims antenna diversity, however the second antenna does not exist.
as for the car amp, still looking into the problem cause, might start digging into the pcb further to see where its going wrong.

I have almost the same issues with the same unit for my Mazda 6 2015.
1. frustrating with the noise at low volume.
2. poor quality of WIFI signal (I'm sending my internet via mifi router)
3. poor quality of bluetooth phone calls.
i had wifi problems with my eonon ga6200f (kld-mtcd) just would not connect at all logged into my router and manually set the channel to channel 3 and its been fine since connects every time now.
i also have a problem with background sound when unit is not playing anything i have an infinity amp so im running through a spdif box from front left and right speakers so figured thats what the problem was been trying to find out if any of the pins not laid out in the manual are spdif out but not getting very far with seller or eonon
Hi all,
I just installed a px5 unit from witson in my seat Leon. Most settings seem to be present, but I do not see the calibrate tires setting. Now I cannot get the message gone in my display behind steering wheel telling me that one tire is missing pressure. Which was indeed the case, especially after cracking on the highway, but anyhow, it's replaced now, so I need to be able to calibrate.
Anyone know? It's not in the tire section....
Thx
Hmmm, no one? Hard to believe I am one of the few or only one who has a car from Volkswagen, Seat, Skoda etc with such a calibration system and an after market px5 android car radio...
EDIT: Never mind, I've got it. I looked for it in the Tire section, but since I wasn't familiar with the term TPMS I did not look for it under that menu option

It is under Vehicule app. Scroll down and you will see TPMS, just press ok and it will calibrate the tires.

Hi,
i`ve got a problem with my
PX5 Octa Core
it`s using MTCE_XRC_V2.93_2
suddenly the sound disappeared.
Everything working nice for about 2 weeks and then it happens.
I checked wiring, trying to back to factory defaults, and nothing.
Strange is that the "clicks" when you touch the screen, or when you setting volume with knob are audible.
I`m looking for solution for about a month and find nothing.
Maybe someone has the same problem, or know what to do?
Thanks in advance
What did the reseller suggest when you contacted them for support?
to update MCU, to that one i wrote before.
no change.
They suggest to send it to them, but for now i`m abroad, and the shipping costs are horribly big

Hi I am having the same issue with the same unit. When i use the CD the sound is perfect but the Radio Tuner has no sound at all. Did you find a solution without sending the unit back?
