hi.. i am new to xda.. if i posted in the wrong forum please inform me..
recently i have bought this unit.. CAR-DA FOR LEXUS IS250 (i cant post links yet)
it’s an 10.4" screen
Android: 4.4.2
processor: QuadCore-R16 1.6 GB
MCU: 5.3.19-23-30-E43101-170207
System version: 4.5.10_20170317
DVD version: 2.13.13-1200xh
RAM: 1GB
ROM: 12 GB
i have two issues with this unit...
1) within the original unit i have an air cleaning button that recirculate the air through an carbon filter.... but this unit have no button to do this (all the other buttons work fine)...
when i change the unit configuration to a LAND CRUISER setting. the unit will show this specific button but it is not working.....
2) the original unit have two lights to tell if the passenger air bag is on or off... this unit haven't which cause the warning sign for the airbag fault to show at the cluster which mean that the airbag system is faulty and not working ... when i reinstall the original unit the sign has gone...
are these issues related to software thing or hardware?? can you help me to solve these out??
thanks in advance..... if there is any more info needed please inform me..
70 + views.. no single reply???
Is it so unusual to have problems lik this??
I am afraid that no one answered because no one can really help you with this kind of problem. Your best bet is to write to the seller/manufacturer and maybe you get lucky and they do something about it.
The integration of these headunits with the car features is usually flimsy at best. For instance, my Chinese headunit can't communicate at all with my Ford Mondeo, no parking sensor detection, no information sent to the car dashboard main display and so on.
It's also true that for some cars is better then others, for instance for WV (Passat, Golf) they managed to have a better integration... it seems that they managed to decode the CAN.
I had similar issues. I missed with it A LOT before it finally changed to the right car. Did you try accessing advanced mode and change the car to your lexus?
So I bought -what I believe- is this Android Head Unit over a month back (Apparently I can't post links yet, but if you search Amazon for "Car Stereo Touch Screen Bluetooth GPS DVD Double Din In Dash Sat Navigation Vehicle Head Unit for VW Volkswagen Jetta Golf Passat Tiguan T5 VW Skoda Seat Hands Free Call Free Map Backup Camera" the result is the item that I got. ) It worked fine once I got it installed, then about a week ago it started having issues (Screen would freeze, buttons unresponsive, and would stay like this until car had been off for some time. Still switched to backup camera on reverse.) I tried to go into settings and do a factory reset to see if that would fix the issue, but now it's stuck with a black screen and the word "Erasing". It still seems to be doing something because overnight the next time I come out the screen is on and it says, "Recovery 7.1.1 :failed to mount /cache (invalid argument)" I've tried several different button pressing methods to try and get to the recovery screen, but it just keeps coming back to the "Erasing" screen regardless of whether I use the Reset button or the Power button (held). I have a couple pictures of settings from the "Droid Info" app (because I couldn't find anything helpful in the settings themselves) that I took before I started having problems with it. So I'm looking for some help regarding getting it into recovery and/or finding out what I'm doing wrong.
Brand is confusing, roundabout on Amazon I found "Malanzs", but it looks exactly like and has the same Manufacturer # as the TMOTEC brand (DS02P051S01C0) and a lot of the pictures of the Malanzs one look like they photoshopped them from the TMOTEC pictures.
One of the things I was trying to find on my pictures but I don't have is the MCU version (apparently this is important for where I will get the most help with my post)
Any help is appreciated, thanks for your time.
I can't help get it working (it sounds defective), personally I'd return it to Amazon quick !

Thanks for the response, I'm in communication with the seller to try and get it returned, but as it's been longer than a month, it's outside of Amazon's return period. I was just hoping to possibly find a solution here.
im not sure the region in which u live ...
but sounds like it possibly overheated ...
and something fried,
ive a px3 rockchip 7.1 hizpo (for ford fusion/f150/exploders)
had it bout idk 8 months, put in some nice sundown 12's in my trunk w/a 40k orion amp and between that and summer in full swing early, im drawling alot of heat, and the same things happenin to mine...
seems over 96 degrees the unit just shats on it self...
the heads still on but android system(ui) crashes...
imma try these few idears while i wait for my px5 upgrade to get here from ebay...
other then this fabricating trick,
im outta suggestions... ive tried everything to get it too

Hi everyone,
Due to the lack of (and dispersed) information about these particular head units, here's a thread where we can discuss and help each other out to make the most of these units. Please note this thread is not for Sofia or MCDB/C/D/E units, there are ample threads about those. I am not a full-time software developer, so please do correct me if you think I'm wrong about something. Please do think twice before experimenting on your unit, no one else is responsible for it but yourself. I'm also dying for a custom ROM, if there's any dev making one for these, please know I'm availing my unit for experimentation. It is a powerful Unit which unfortunately is plagued by software problems which is why I believe a dev can make a better job than the manufacturer.
Also, special thanks to @surfer63 for his Joying Extra Tools (JET apk) which has been a critical tool for rooting, among other things.
I will be taking the unit out of the car and opening it up to install a heat sink and take some pictures of the insides, let me know if anyone's interested in close-ups of anything on the board.
{Reserved for Hardware}
The unit was advertised as compatible with BMW X5 and E39 (5series 1996-2001). My car is a 1997 520i with the low-end dashboard so that's the context I'll be speaking in. The unit shipped complete with adapter cables which connect to the original connectors for the radio, magnetic GPS antenna, external mic (more on the internal mic later), 2 USB ports which are permanently attached to the unit (as well as an sd card slot), a couple of flimsy brackets which screw in place of the original radio holder. However 2 screws which attach the unit to the brackets were not provided and i had to rummage around until i found 2 screws that fit. Unfortunately the original radio antenna cable on the car doesn't fit the unit, however the bundle of cables has an antenna plug with it, it's just a matter of replacing it (someday, as I don't really use radio at all).
The Unit is reporting to have an ARM64-v8a architecture and an rk30sdk board, 4GB RAM as well as 32GB of internal storage. External storage is detected almost immediately as well and I had no problems with files stored on a pendrive. The CPU tends to run hot, occasionally going beyond 80degrees Celcius, I therefore have a small fan and heatsink ordered which I will try to squeeze into the single-DIN box. Worth mentioning it has buttons and a knob on either side of the screen which are backlit and positively responsive. Regarding the in-built microphone, it "works" in theory, ie. it hears you if you tap on it, but it doesn't hear my voice even with the engine idling, let alone cruising down the autobahn. Fortunately it comes with an external mic, I'll hook it up when I pull it out for the fan job.
{Reserved for Software}
This is the latest ROM & MCU update from the manufacturer:
Android Version: 8.0.0
Build number: px5-userdebug 8.0.0 OPR5.170623.007 eng.bsp.20181107.190240 test-keys
System info: APP 1024x600 2018-11-23 08:48:14
MCU Version: 2018-11-23 16:12:28 JY_(R68*)__26_C26_CAN(All)
BT Version: BLINK_8723DS_RELEASE/2018:10:08:17:05:26
DigitalAmp Version: Unknown
CAN Version: Unknown
Serial Number: 00000000
I'm not going to give the Wifi Mac address for obvious reasons.
Cold boots are pretty quick, it's usually done in half a minute. It has a rudimentary "recovery" mode which is achieved by pressing the reset button with a needle 3 times, and after a pause, a countdown is shown under the boot logo, at which point one has to insert the SD card into the right hand slot. If it identifies the ROM on the SD card as equivalent or better, it starts flashing. If it doesn't recognise it, it does apparently nothing and leaves you with a black screen until you remove the SD card and boot it up again.
I have on several occasions attempted to flash TWRP recovery image as well on the unit, with no success.
Description of operation & issues:
Ever since the latest ROM Update, I've been having issues with the WiFi: despite the dozen wifi hotspots around the neighbourhood including my phone and home wifi, the unit doesn't "see" any until I completely reboot it.
The ROM provided by the manufacturer doesn't have a proper bluetooth menu. Despite being equipped with Bluetooth 4.0, as it stands for now, there is no proper bluetooth menu like you get on your phone/tablet/etc... a bluetooth app shortcut does open this menu but the menu doesn't offer any options or work at all except for the on/off toggle.
The CPU runs hot, it is a well known issue and I'm intending to install a heat sink and fan on it.
Several other settings menu items usually found on phones are also missing.
There buttons of course are lit up but the colour options are just 7. There is no way to choose your own colour and I don't know of any app that can do it on this particular model.
So I've opened up the unit and took some pictures before i stuck on a few small heatsinks on the FYT6026 bigger metal heatsink as well as a small fan. I've not taken pictures of what I've done, but you can all suppose how it's set up. It's pretty easy. I've got more closeups of the board for whoever wants to see them, just ask.
Hey @surfer63 or @gtxaspec @xxRaiyanxxYT do you know what the connector circled in red (4 pins) is for? It was not connected to anything in my unit. The other 2 are USB (5 pins) and the one on top (2pins) is microphone.
Sorry didnt upload for some reason.

Connect those Plugs Red, Green and Blue
Wondering that myself... Could it be power for a fan?
I have the same unused plug in mine.
Any info would be appreciated
Cheers,

What? No you didn't understand. I disconnected the plugs before i took the picture to get a clearer view of the board. The 2 plugs in the Blue circle are both for USB cables that go out from behind the unit, and the green one is for the external microphone which I also use. The one I don't know about is the one in the red circle. it was not connected to anything when I opened the unit and I'd like to know what it might be useful for.

I was thinking the same thing, I was going to hook the fan up to them but I needed to measure the voltages across those pins and my car is downstairs in the basement and I don't have a proper kit to power the it up on the bench. I would've made one but I was in a hurry yesterday. I need a whole day to mess around with it properly and find out what each part does but right now I'm working through the weekends until the end of the year. Until I get some time like that, I'm trying to gather some more info about it so I won't take it out for nothing (it's a ***** to install this unit back in the car).

I will see what I can do.. Running my unit on the bench right now with a CPU power supply...
Might be able to test it tonight.. If not it will go to this weekend I'm afraid..

Good stuff, that'd be great, thanks! Which unit have you got? (specs) And have you managed to change the bootloader or flash a custom rom on it? Feel free to share pics of the motherboard.

I have the JY-HOS01P4
8.8" 4GB/32GB
No Hardware button at all. Not reset hole.. nada (Will make it easier to weatherproof.. )
Will at some point put a heatsink on it.. But being single DIN the room is limited...
So far I have only have it rooted and JET installed on it.
I do not think I will mess with the bootloader/custom ROM as it does pretty much what I want out of the box.
Testing different software now.
And the unit will be installed in my HD Roadglide.
So basically the sound output will be 2 fold:
Speakers driven by an external AMP so I can shut of sound by turn the amp off thru the settings
Bluetooth comms headset connected to a bluetooth transmitter taking it's input from RCA jacks
My requirements are the following:
Launcher: CarWebGuru
Radio -> will use stock app
MP3 -> Still testing players but for now I'm happy with google play music
GPS -> Osmand+ with data on SD card
Phone-> Android Auto + Headunit Reloaded (will finish testing and probably will buy.. Do not link ZLink.. even thought it works sort of ok) At this point I'm able to dial/see the phone on the radio and hear/talk with my BT headset
That is pretty much it.. Might attempt to put a DVR at some point...
I'll take a pic tonight of the board but aside from the location of that big capacitor (Mine is beside the wall of the radio) it is pretty much the same as yours.

Ah I see, so what they're doing is basically hooking up a different screen to the same single-din box. Have you had any issues with the wifi since the last update?

I have not seen any issues.. Mind you I only have an internal network.. Still waiting for internet to be installed ^%@%#
I had to hotspot my phone for connectivity when needed but it is chewing my data!!!
I did all my downloads from work and brought the files/apk home to install.
What kind of issues are you seeing?
Which version of the latest do you have? the first 2018-11-7 or the 2nd 2018-11?
(I hate how the have they same file name.. Joying is pretty bad naming stuff...)
Hi,
I tested the header last night and got nothing. 0 power
Now, I have not had the time to play with the settings in the radio so I do not know if something would turn that on.
Cheers,
haven't tested it myself, but from my memory this red-circled connector has something to do with audio (either Ins or Outs).
Here is the picture of the inside of the single DIN unit

I didn't realise they published the 2018-11. I downloaded the previous update, 2018-11-7. I think they published the second one after the first november update gave us issues and somehow forgot to put the full date on it. I'll try flashing that update at some point and see what happens.
Hello, i am new on this forum and i can see that there are a lot of expert with really precised answers.
I am french and i bought one head unit on aliexpress.
I am on android 8.1 SP9853i and MCU version in attached.
I am facing some sound issue... everythings works great (option camera etc ) but i have some intermittent sound cut like if the system try to load something. This issue is for the global sound (bluetooth, radio, internet ) it' cut for around 2 or 3 seconds everytime and sometime the lighting button on left swith off quickly.
i tried with canbus disconnected and all other wires but still occurs.
If somebody can help me..

Like all chinese sh...t, you need to open the HU and check all the flat cable.
Unplug and plug very gentle on motherboard and videooard (behind display).
Thanks a lot for your reply !
I already did that for flat cables byt it's not better. I will do that again to be sure.
It's really like the system search something. I changed the car model in MCU, i tried to unplug all option cable behide but nothing better. Do you think that could be a problem of MCU version?
And another thanks to take time to help me !!

Maybe you have problems on tension plugs(12 volts).
Try to understand if the issue come only on bad streets when the car is shaking.
Hello guys I have added a fan to this unit in ACC pin , but the touch and touch buttons no longer work I tried to correct the touch calibrator but it never responds, it works fine by usb mouse, I want to know if re-flashing the firmware fixing the isse , I don't think Hardware issues because all connections and cables are good, can anyone help me to know which firmware is suitable for this unit and how I can download it and flash to the unit, or how to fix it, cuz i bought from just 2 weeks ago i didn't install to my car yet,
Thanks
