Watchout Erisin aftersales - MTCD Android Head Units General

Be careful when you buy to this manufacturer because I bought more than 4 units and they don't help when 1 unit is defective, only way is to pay shipping back to china when you buy unit from UK warehouse and solution is much easier, send only defective spare part, because I am not willing to pay anything when product is within warranty, and the time I will be without using it.
So they only care about sell, cheap and poor quality devices and later after send few e-mail, they stop answering.
There are other better manufacturers for good car head units so... STAY AWAY FROM THIS BRAND ERISIN!!!!

yeah agree..
worst quality units i have seen so far
what was wrong with your unit?

Erisin are not a manufacturer they are just sellers - they buy from a variety of manufacturers and then sell them on, they know very little about what they sell and are only useful for the occasional firmware release. If you buy from ebay or with Paypal you should be covered though.
To find out who manufacturers your units go to settings/about device, the 3 or 4 letters after "MTCD" will tell you.
The devices have a few bugs but are not poor quality and the bugs can be sorted with help from fellow XDA users.
What problems were you having ? Its very likely that they can easily be sorted.

mate stop telling people what to say it is not polite, specially when you are not 100% sure of what you say
erisin=KLG
they are not sellers, i am 90% sure of that
the units are very low quality. Bluetooth and wifi problems (can't use both at the same time) , and touch screen problems
these are not software bugs that can be sorted. they are hardware
i have had 3 units so i am quite knowledgeable about them, KLG units are just the poorest quality of all

At NO POINT in my previous post did I "tell people what to say". What I did is give advice using my pretty extensive knowledge of these units and their manufacturers
Having dealt directly with several manufacturers of these units, sold some myself, owned around 6 units from different manufacturers and been active in the XDA forums about them for 3 years, I know EXACTLY what I m talking about, I was offering you and @numind help and advice, dont take it if you dont want to, but I know what I m talking about when it comes to these devices as my thanks meter clearly shows.
Its long been established by myself and others on here that Erisin are sellers - I am 200% sure of that, so you are plain wrong when you say that they are not.
You dont have a "KLG" MCU because theres no such thing, what you probably mean is that you have a KGL MCU. If you have a KGL MCU then you have a device made by Shenzhen Kai Ge Le, but Erisin DOES NOT = KGL, Erisin sell units from several different manufacturers, not just KGL and other sellers also sell KGL devices. Indeed I just bought an MTCD unit from Erisin and it has a GS MCU, GS is a different manufacturer - the letters after "MTCD" denote who manufactures your unit, GS are an entirely different company from KGL.
I made no mention of software bugs, I said its highly likely that "any" bugs can be sorted out, both software AND hardware bugs can be sorted using advice on XDA.
If you havent had a unit made by anyone else other than KGL then I m not sure you can say that KGL devices are "the poorest quality of all", but nevertheless I certainly have heard of more problems with KGL devices than others, so I am inclined to agree with that, but the problems can be overcome.
In all my 3 years on the MTC forums I ve not heard about anyone not being able to use wifi and BT at the same time. Have you updated your MCU ? Have you changed anything in factory settings ? If so (I m guessing the answer is yes to both) then you may want to read @marchnz's Cross compatible MCU thread because he has found out that its possible to use other manufactures' MCUs on MTCD devices and this could sort your wifi/BT issues. Also lots of KGL MTCD devices use the Realtec rtl8723bu wifi/BT chip (as do 1000s of other devices the world over from Android head units to computers), it may be something to do with the antennas, KLD MTCD devices also use this chip and people have improved the reception by simply adding longer antenna wires. Maybe KGL have only connected one antenna (the rtl8723bu should have 2) and that is your problem ? In which case it could just be case of soldering on another. Maybe one or both have become detached, I ve heard of the earth lead for the radio tuners on MTCB KGL device becoming detached before. Have you opened the unit ?
I have heard of touchscreen problems before, its often centred around the connector, have you tried re-seating it ? Can you be more specific about your touchscreen "problems" ?

ok i do own 3 other units KLD, KSP and KGL
KGL is the lowest quality and i insist
the unit i have uses the same chip for BT and wifi and this causes interferance. when BT is connected the wifi is useless.. you can search the forum and you will find many posts about that.. my KSP and KLD do not (although they use the same chip for BT) but, i think it is not combined.
I soldered an external antenna but this did not help at all i itried all MCU's but that made no difference..any way it is the implementation of BT and wifi in these units that causes the interference problem on the 2.4Ghz freq. it will not be solved with any software update.
the most serious problem is the touch screen deffect.. the touch screen is a 9 inch, the center part of the touch overlay works ok but 2 cm around the screen the touchscreen has 3 dead zones parallel to the frame so when you draw for example the cursor jumps these dead zones.. any small button that exists on these dead zones is unclickable.
i tried removing the cable change it etc.. and this did not help.

this member has the same problem so it is not a coincidence..
i will probably return the unit and buy something else
i am really not sure who is the manufacturer and who is the seller anymore, and i don't really care.. you might be right i guess and i apologize for that.

OK, we agree about KGL being the poorest of these units then.
It could indeed be down to the mobo and the way KGL designed it, but @marchnz has only recently found out that a lot of MTCD units can actually be made to use other MCU types (unlike MTCB/C units) so it really could be worth you reading his thread as it could help, maybe a KLD MCU for instance, could sort it out ? Its worth trying. And did you have one or two antennas ? You said "I soldered an external antenna" suggesting just one. This could be important as its both a BT and wifi chip.
Does the screen work if you attach a mouse (not that it would help much when driving, although an air mouse might, I guess thats not the point though) ?
I have read of other users buying new screens, have you looked on Aliexpress ?
One of my 9" units has at least a (very annoying) 1 cm gap between the digitiser and the screen, just out of interest does your KGL ?

Almost all px5 units are suffering the bad wifi reception and/or speed.
The closer the wifi source is...the smaller is the issue.
Most of people are using the wifi units by means of wifi tethering from their phones....which is a very close source to the antenna (which is my case)
When arriving home it detects my home's wifi but speed ia very low (when my phone dpes not lack of any speed connected at the same time and from he same place - the car)
So...all we are having similar problems (which can be affected by interference) but specific units are unusable even having the source close to the headunit.
As the software is the same for all px5 units (including the kernel which recently has been updated on the August 3rd ROM published by dasaita) the problem is on the board
We should all open the units and check how our units arw assembled and compare with the ones that are correctly working
The bad quality of soldering on antennas could be the cause of yoir issues...

i have some electronics knowledge.. BT and Wifi both use 2.4ghz so the interfere more or less
this problem occurs in many HTC and Samsung mobile phones also.. and also occurs in most MTCD devices BUT.. the wifi signal is still usable. In my situation playstore fails to even connect, speedtest does not even find a server.. so it is the implemantation.
this device has 2 antennas, one for BT (a cable really) and another for WIFI (another cable).. but it is the chip itself that has the issue.. in my other KSP unit there is interferance and the wifi does slow down but it is not killed like the KGL. I do think the KSP has a separate BT and WIFI chip.. although both state MD725 for the BT in factory settings..
anyway i just tried HA and GS mcu's but the don't help for the touch screen issue.. so it might be a defective digitizer i guess

New motherboard from Dasaita is built by two different chip modules for wifi and bt.
What's is strange is that he new WiFi module is not dual and it seems to be very old

If its only affecting RK3368/PX5 units then its deffo a software problem related to the SoM.

My KLD MTCD unit has holes for a BC6 BT (BT only) module, as used in MTCB/C devices and I have a spare one, I wonder if using that would improve things, leaving the Realtec just to do wifi duties, not sure how youd "tell" the MCU not to use the rtl for BT though.
On MTCB/C units a small heat sink makes the wifi much faster, some people with MTCB/C units also suffer from slow wifi when connected to a router and downloading large files (although I ve not experienced this), but MTCB/C units have separate wifi and BT chips. TBH though all antennas are "cables really" A tiny heat sink is worth trying and costs peanuts. MD725 means its the same rtl wifi/BT chip as KSP/KLDs.
Are all your units MTCD ? Cos if you have an RK3188/PX3 one you could swap the SoM and see if the problem improves/goes away with an RK3188/PX5 SoM, if it does then @ikerg is right and its a SoM/ROM software problem, not hardware, which would probably mean just waiting for updates or hoping a dev on here who knows their stuff can sort it.
Yes I did mean a void, I have two 9" units and one has this void, its weird, just wondered if yours did.

The point is that backlight is dead, only works volume knob led, so I asked to many Erisin contacts if this was a common failure and if they could send to me spare part and I fix it, but they just stop answering.
Also other fail I detected for new PX5 unit is about ignition output filter, there is a sound peak after run the ignition key, and with older PX3 this didnt happen...
Anyway you can't expect too much for these cheap units

They changed it to 6 months.

Regarding these quality problems from Erisin crap, what would you think could be an option for replace the head unit? maybe Dasaita? some modle in the edge between price and quality, about 400usd...
All people should know about different brands, I would support a kind of satisfaction poll with positive and negative points.

All people should know about different brands, - different manufacturers.
The GS and HA units appear to be the better quality units. For the record, I have a JY and while it isnt bad, there are shorcuts. I have a GS board obtained as a spare part, it was with the GS board I was able to create a Jig to recovery bricked/corrupt PX5 NAND.

Eonon or Pumpkin?

I'm trying to decide between two identical systems with minor differences;
Eonon will include a slim IR remote (which I would consider useless, except that the reason I need a new head unit is my old one has a bad screen and a remote would have made it usable)
Pumpkin does not have a remote (but still has the IR port) but has a 1024*600 screen as opposed to Eonon's 800*400.
Thoughts on which to choose?
Anyone have a remote they aren't using they want to sell to make the decision easier?
I recently bought an Eonon GA2114 to replace my old AN21U. First impressions:
-good mechanical build
-internal microphone is much better than AN 21U's
-SWC work way better
-very responsive customer support
-different build from what I have seen on this forum. Wanted to do the BT mic mod but gave up - too much disassembling involved
-slightly wider than standard 2DIN, needs fiddling with the dash frame
Had a weird issue with BT: with any KLD ROM (including Eonon official) I was unable to use BT for phone calls. It does work, however, with Joying ROMs
Hope this helps

That's the one I'm looking at. Have you used the remote that comes with the unit and, if so, is it even useful?
I'm a bit surprised that this hasn't turned into a thread of people arguing that 1024*600 is so much better and others saying that there's no practical difference between that and 800*400.

Haven't touched the remote, not a fan. Don't really see the utility of a remote for the driver, the screen is very responsive and so are the SWC buttons, finally. On my previous unit SWC controls were erratic ( I believe it happened because of the low priority of the control process). A remote would probably become useful if I had multiple displays in the car and the passengers in the back seat would want to change the movie or similar.
As for the screen, I am really happy with it. I actually ended up with this resolution by mistake, I was also looking for a 1024*600 but got attracted by the bigger screen of this unit and somehow missed the fact that it is 800*480. Don't regret that, 7 inch is really a significant improvement over 6.2.
I have a GA2114 too I'm pretty happy with mine, only issue I have with it is that the Bluetooth calling can sometimes be quite distorted and people can't hear me which I know is a problem with most units, I just havent got round to taking mine apart to modify. Mine seems to be fine sometimes though and people say they can hear me fine.
I had a WinCE Eonon unit before my GA2114 and the reason I went for another Eonon unit was because they were so reliable, had it for about 2 years and didn't have one issue with it.
EDIT: One small issue I forgot to mention was my microSD card slot in the front seems to be quite dodgy, the card doesn't click in properly. I can get it to sit in though by pushing it in then putting the cover back over it to hold it in place.

I have bought Pumpkin head unit with ASIN B016I7C7TK on Amazon.co.uk , which includes an external wireless SWC control and it is very convenient.
It has 7-inch 1024*600 screen and Android 4.4 Quad Core 1.6GHz system.
Really impressed so far with this, for the price its definitely worth it! Had no issues so far and customer service has been very good.

I just installed my ga2114 and love it but also do not have Bluetooth audio working for calls. It works great for regular audio. What rom should I be running to fix it?
Also I notice a slight audio hiss. Did you experience that on your unit? It's not enough to drive me crazy but it's definitely there once the radio boots up. Aside from that, I love it so far.
glad to see some praise for these units, I had my eye on one from eonon

Which MTCB head unit has no microphone issue?-

I'm looking to purchasing a MTCB double din head unit, however, I've been reading about microphone issues even with external microphones. This requires hardware modification to fix for some models. However, I cannot determine if all units are like this, or only some. Please let me know!
Thanks!
All the devices I have seen are basically the same and I think actuall built by the same people. They are just sold by many different vendors. So I don't think any of them are free from this problem. The repair itself is not too bad, a fine tip soldering iron really helps. But if anyone knows one without the problem I would be happy to be wrong!
I have a Joying HU and have not done the mic mod or even hooked up the external mic. Using only the onboard mic, my android voice control works fine and BT calls work as expected. Friends say I sound fine and no echo issues on their end.
I too have a joying unit with no mic issues. I think there might have been a hardware revision recently. FWIW pumpkin is selling what looks to be a MTCB with a parrot bluetooth in it.

I've the new Pumpkin and the microphones are still in parallel making the sound as bad as it use to be. No real improvement. Had to cut the wires
on the front one.
The thing is that they promise 24h response, but sine it's Chinese New Year the response time is 7 days.
I have a joying and did not connect the external mic. Bluetooth works fine, I hear them and they hear me no problem. I had an Erisin with no external mic and had no problems either.
I was just wondering which country people are in, I am in Australia so we drive on the right hand side of the car and the mic is on the left hand side of the units, therefore the mic is closer to the user [potentially] than us, maybe that is why it is clearer? just a thought bubble.
LHD, wouldn't think RHD would effect it much, if any. Road noise and speech volume would have a greater effect.

Let's Talk About the Joying JY-UL135

So, this is one part commentary/review(ish), one part questions. Let's talk about this dude. So, I had a Pioneer DVD unit in my 2003 F-150 that I was really unhappy with (for several reasons I won't bother explaining). Being a bit of a tech geek, I really wanted something better, that wouldn't require an extra add on unit for navigation, and would give me a little flexibility wherever I wanted it. I was really surprised that there wasn't a better selection of head units that run Android on the market, but being such, I found Joying pretty fast. I read a bunch on here, and decided it was worth throwing the dice and a few hours at. FWIW, I ordered off Amazon, and got the JY-UL135 unit (Android 5.1.1, 7" screen, 1024x600, 16GB, 1.6GHz quad core). It seems Joying has a couple slightly different units with basically the same specs for sale. I have no idea what distinguishes them besides a slightly different bezel setup. I *think* this is the newer one. Maybe. Who knows.
Thoughts and Comments
Trust the reviews. This unit is a tiny bit bigger than it should be. I don't know why. So be it. So was my Pioneer though, but this is about another 1/8" wider, so I'll need to barely widen my already modified mounting hole.
Soldering up the wiring harness was no trouble. Uncommonly used wires were neatly capped too.
The instructions, labels, and some of the in-system notifications are in pretty rough translated English. Not a big deal, but just be aware.
If you want to do a custom boot logo, for some reason it's hidden behind the Factory Settings, with the code 126 to access it.
Unit feels plenty fast and responsive, and the build quality is acceptable at the price.
Wifi connected right up.
I did have trouble connecting to my Bluetooth OBD2 reader, which seems to be a common complaint. I'm ordering a $10 one that matches the Elm327 unit Joying offers for $20. We'll see if it works.
I prefer OBD Fusion over Torque, personally. Once the above is resolved, I'm interested to see how it compares on the unit.
Included GPS antenna has plenty of length, and seems to get a signal without issue.
I grounded the brake sensor wire right to the chassis ground line to bypass it, need to confirm that works.
Was able to pretty closely match the backlight color to the rest of my dash.
Going to use an old Micro SD card to try storing offline Google Maps data for those cellular black hole areas I travel to.
Also planning to get a dashcam to try out the DVR functionality. You never know when that could be $35 well spent.
Audio seems okay. Not great, but acceptable for my use. I do have one speaker not working that I need to diagnose. And I don't currently have an amp/sub, but do think I'll add a small one down the road.
Overall, I'm not in love with the launcher installed on it.
I still need to test phone mirroring, connecting via tethering to my phone's hotspot for nav data, install my backup camera, modify my external mic connector to be compatible with the input,
Questions for the Hive Mind
Does anyone know if these newer units benefit from the audio hack/mod discussed elsewhere?
Rooting. Do it, or no? If so, what's your preferred process?
What's your opinion on different launchers?
The Factory Settings menu appears to have quite a bit of stuff in it. Anything besides the boot logo really worth paying attention to?
i recently got the Jeep specific one from Amazon, Joying 5.1, should be the same stuff.
Pretty happy so far, I downloaded my city in Google Maps, but I didn't see an option to save it to a micro sd card. I didn't have to solder anything since I got vehicle specific, all plug and play. Also I used an adapter to use the Jeeps existing GPS. Fit and finish seems pretty top notch on mine, at least for the physical buttons.
I was considering rooting to try to do Apps2SD or something, I just want my Google Play Music playlists downloaded. I can do it, but it fills up the memory, and I dont have the option to put it on the micro sd card.
I was also confused by the Factory Settings options. There was an IPOD part listed as No. I changed it to YES and it gave me an ipod app, but it just immediately crashed, so I turned it back off.

I didn't even actually realize they made brand specific models when I ordered mine, though I think outside of the wiring harness, that maybe doesn't matter. My truck is a 2003 too, so there really isn't anything in the way of fancy electronics in it to deal with, which probably helps.
I just got my backup cam mounted on my license plate, going out after work to wire it up hopefully. It's hot as hell here right now though, so we'll see how much I want to stay out there and do it with the sun still shining though.

IPOD I believe is quoted to not be working with that model.. How is the audio with the Jeep specific one? It looks just like the current 4.4 version and I was not sure if any hardware has changed. I was also looking at the 7in universal one that is mentioned by OP but wanted to know if it is better than the jeep specific one as far as audio hardware and sound. I know the screen size is smaller but was not sure if there is anything else. Any complaints so far on the 5.5 version of the Jeep one??

I dont know anything about the 4.4 version. All i have is the 5.1 version, but i find that many complaints I read about these things are not evident in my version, so maybe stuff did change. For example people say you have to buy some antenna adapter, which I did not need, it had one in the box. FM radio sounds fine, although I dont listen to it. I just tried it so see what's up.
I have a 2016 Jeep Wrangler Unlimited, I had the 430N with the base audio. I had replaced the factory speakers with the Mopar Kicker upgrades. Sound is 100% better with the Joying.
I have a lot of details and pics here:

I'm thinking about buying this head unit for my car, and I was wondering if anyone can give an input after a few months of usage.
What I'm worried about is the 1gb RAM , when there are new versions with 2GB of RAM
Do you think the 1GB is a deal breaker?
Thanks!

If you dont mind things going slow, otherwise get the 2gb. Also, if you plan to use a dashcam and rexord, then def get a 2gb. I just ordered the UL135N2 this morning. Should get to my place in Wisconsin just after new years.

So, did you buy one 2gb ram model?
or replace with 1gb ram model??
I'm using 1gb ram model and I want to upgrade to 2gb ram.
Your F150 is a non-standard DIN fitting. It is about 2 mm too short (vertical face) for a standard 2-DIN head unit. No matter what unit you bought it will "appear" incorrect but it's really just Ford brilliantly coming up with their own size to be special.

I had a Jeep specific unit from Joying that was a MTCD, Android 5.1, and only 1GB of RAM. I loved it at the time.
I got a new unit. 8inch double din, Intel, and 2GB of RAM
I love the bigger screen, and the performance is no comparison

The Chinese units are not quite Double Din either. I know on the Jeep forums, every time someone puts in an American double din, people have to file things down to fit.
But when I put the Joying Double Din, it fit just fine, no filing required

This is what you're looking for;
https://en.wikipedia.org/wiki/ISO_7736
To summarize, USA double DIN = 7" x 4" (177.8mm x 101.6mm)
Metric double DIN = 180mm x 100mm (7.09" x 3.93").
In other words, the Metric double DIN is nearly 1/10th of an inch wider than a USA double DIN.
The Chinese head units are made to 178mm x 100mm for the UL135[N[2]] or 178mm x 102mm for the UL128[N[2]]. Don't ask me why they went for 102mm on the 128's. But essentially, the USA DDIN is just a little bit TOO NARROW for these head units, which seem to be targeting METRIC dimensions. Well, except for the 128's height, which is a bit closer to USA spec, but still marginally over.
Hello the team XDA,
I have mounted a joying UL-135 in a my car with a special harness.
I have a problem with the sleep mode. Head unit never shut down completely.
When a turn off the keycar, head unit shut down...then after few minutes, touch lights are shuting down too.
Then it's impossible to turn on the head unit.
After a night of parking, when i turn on the car, head unit start quickly to the previous postition without booting from Logo.
Do you have a solution ? i have tried to enter in the developer menu but it needs a password and i dont have it ?

Is it a UL135? Or is it a UL135N or UL135N2? The latter two will deep sleep when the ignition is turned off, allowing them to start up *instantly* when the power is resumed. Your description of device behavior is consistent with N[2] units. In fact, I'm not even sure it is possible for a UL135 to do what you describe, since if it wasn't shutting down, the screen would remain on.
sorry it's the JY-UL135N
Anyone been able to root the UL135? I don't have the factory settings menu.. So I have no idea what to do..

is there reasonable radio reception on new units with integrated twin fakra connector

Hello,
as i crashed my old pumpkin head unit, i am looking for a new one, for my Audi A4
(my current model is out of stock)
I consider ordering this one now:
http://www.erisinwholesale.com/special-car-dvd/audi/erisin-es3078a-7-android-51-car-dvd-gps-dab-for-audi-a4-497.html
This one has already the Audi/VW main-connector right at the radio, also a twin fakra connector and even an integrated CAN-modul. So there will be way less wiring spaghetti behind the unit, which seems really nice to me.
But i am a bit afraid, that the radio reception could be bad...
I don´t really trust this ex China-factory twin Fakra connector there. Usually one had to use a external powered antenna boost-adapter for those android head units. And even with those boost-adapters, the reception was never as good, as with the original radio. Because no adapter could replace the twin-receiver diversity function of the original VW/Audi radios.
Sooo....
With this new unit, i would have to directly connect my antennas... without any adapters or boosters...
Has anyone an idea if this really works well on those new units??
I don´t think those new units have two receivers installed?! Or do they?
Is this twin fakra adapter at least powered?
I hope someone has already played with a similar unit and can give some comments..
thanks!
In theory it should be better with a port for the diversity antenna as well. At the end of the day this is the main reason why the original radio has better reception.
I've got the Erisin ES3015V which I suspect is similar (it has the same VW-specific connections). I have never owned any other android head unit, so I can't compare the radio reception, but I can tell you that it's not as good as the original radio. My guess is it's somewhere in between.
Hi,
Thanks!
Yes, your ES3015V should be pretty much the same, just with a different front cover. I have ordered this ES3078A now anyhow... Hope for the best...
Do you know, is this Twin-Fakra Connector at least powered? (12V) or do we need to add something here on our own?
Are you satisfied with the rear speaker volume?
This is also something, i had to modify on my first head unit.

Sorry, don't know if it's powered or not, but I'd be very interested in hearing about your findings .I haven't noticed the sound from the rear speakers being too low, but then again, sound quality overall isn't exactly brilliant. I've been thinking about adding a powered subwoofer, but I've read a lot of stuff on here about these units being underpowered on the RCA outputs, so I'm not sure if it'll be worth it.

those 10" units are known to have a space between the display and the actual touch, resulting in almost a 3D / depth-like effect of the stuff onscreen (when watched from an angle, which happens usually where the driver or passenger are looking at it, no one is looking straight perpendicular to the screen). Is this also the case with this unit?
Is it known under different names? I’d love to find a thread’s talking about software options. Anyway, I don’t really notice any kind of a 3-D effect, if you look at it from an extreme angle, it does look like there is a small gap, but I definitely don’t feel it when pressing on the glass. It’s a beautiful display, a lot nicer than I would have expected.
Bluetooth seems not working in the 20190428 update.
Tried update and clean install, neither Bluetooth worked. The rest so far so good.

yes, the display is beautiful, very good contrast and color saturation.
i've seen one installed in a car few days ago, and the first thing i noticed (was sitting in the passenger seat) was the depth effect. This effect is not present in all other units 7", 8" or 9". You could see it more in the launcher main screen (it was an Ownice), less in FM radio app or mediaplayer, navi, etc...
another thing that i didn't like was that for my car i had to cancel the airbag warning connector since the unit comes with own mask and for VW/Skoda the mask that is used for 8 or 9" units has a airbag connector. The Ownice 10.2" did not. Also an issue is the huge screen at night with white background apps which even at lowest brightness they still blow your eyes off
I may buy the dsp version soon from ali express.
I need to find out if the mcu is an MTCE first, as hal9k will be developing his rom for px6 mtce, and i wouldnt be suprised if malaysk adds it too

to clarify this, i suspect the ownice i saw had that 2.5D+nano screen, because my 10.2 dasaita has no depth issue whatsoever on its ips screen.
reg. airbag warning, it's just not visible, you need to take it out from the old cover together without unplugging it and just place it behind the screen. it won't give errors but it's not visible either...

also no issues on my IPS screen either! Great unit for what it is. Of course there are little issues here and there like all units.
I rooted mine so I could freeze apps I don't need and really clean everything up

Do you have advices to root dasaita px6 ?
Thank you
Waiting infos on root aswell
What about fastboot? Can it do 2s boot? and sleep with <1mA low power?
Has anyone looked at (somehow) adding HD Radio?
My Rav4 HU has this and I've found it to be much better at receiving a signal (where I live anyway). I'm looking at a PX6 dasaita unit on Ali (also), but they all have the 6686 radio chip, where the 6688 radio chip has HD Radio included. I wonder if the 6688 couldn't be somehow retrofitted? Yes of course there would have to be pin compatibility etc, has anyone looked at that by chance?
I'm so tempted to just buy one and say scr*w the HD Radio... but sadly it's about the only thing I use the HU for! it would be hard to give that up as I almost always have the screen off
Cheers, they sure do look nice, would love to have one. Not sure if it would suit my needs though, when all said and done.

Do you also have carplay wire/wireless chip on unit? did you see if that is able to charge your iphone with carplay on?
ALso have you driven longer than 2 hrs? with this unit ? I had PX5 and it used to reset over using it continuously for 2hr or more. and also PX5 was not charging iPhone while carplay was on.
If possible could any one update me on this?

It does charge while doing CarPlay because it’s wireless so I just plug it into my charger. Works totally fine for hours on end. I’ve got an annoying bug with VLC thinking it doesn’t have delete permissions unless I manually grant it twice, but that’s unrelated. Also a bug with my iphones voice to text requires me to type a character first before it’ll pick up mic input, but I think it’s an iPhone issue.

So far looks good then.
I do not find any description on link you got on amazon, specifying about wireless carplay, i tried contacting Iris he replied that there is option to get carplay wire/wireless on PX6. I ask him to send me link to product he is yet to reply.
Did you have to specify Dasaita to get you wireless carplay? or its just standard now?

I could be mistaken, but I think it's wireless. I hadn't asked for anything in particular, so it might be standard now.
I have dasaita - car play works on wire plus you have to have additional box/device ( can buy it in bundle with head unit). When iPhone connected through it - CarPlay works seamlessly and your phone is charging.
One more thing - you need to have application for CarPlay too.
