Questions;

I am on Android Version 8. Can i upgrade to Android Version 10? How?

The Build Number has HCT on it. Can i update with HA? Or need to update with HCT?

What does OTG stands for?

I am on PX5. I shud not install PX6 correct?

I am on MTCE HA. I have already update to the latest (image is the one not yet updated)

Thanks for your reply.
[MTCD Android Head Units General] talrhv:
You need to get the update for PX5 unit PX6 will not work for you.

OTG is the usb port that is used for CarPlay\android auto.

you can use the HA version of PX5.

HA = Hot audio = Dasaita, but it can be used with all PX5 units even of other brands.
[MTCD Android Head Units General] Sylvan151:
Thanks.

How about the Android Version?
[MTCD Android Head Units General] talrhv:
you can update to Android 10. just use the PX5 HA android 10 version.
[MTCD Android Head Units General] mel0ntek:
Hey all, been lurking a few days and read through the entire thread. I do embedded software engineering at my current job, so I hope I may be able to apply some of that knowledge here.

I just picked up a PX6+DSP unit for my WRX.

I am using this with a Pixel 4xl.

My unit had some pretty old revisions running on it out of the box:

RK3399-10-2020.06.09

MTCE_HA_V3.57_1

(factory settings password:126)

Android Auto was working sporadically over USB on this version and no wireless capability.

I updated to the 12.17.2020 OTA update and 3.69c. Upon rebooting, Android Auto connected itself automatically over bluetooth and setup the wifi connection. Seems to be working great, however I would prefer to use the head unit normally and only connect AA when I want to. Disabling wireless in AA settings on my phone prevents it from auto-starting every time I connect the phone/HU.

I also went into the factory settings and enabled BT network sharing (BT tether on phone settings) and rebooted. I now have the <--> icon at the top of the HU display. However, I cannot get any network connectivity (load a webpage for example) on the HU.

Are you able to tether data over BT while connected or otherwise?

The issue I am seeing here is that since the HU acts as a hotspot when AA is connected, it doesnt seem to know what to do for its own internet access. Android falls back to Mobile data if it's available when a wifi connection doesnt have internet access, so the phone still works fine. I would assume that the HU would do the same even in hotspot mode and fallback to "ethernet" (<--> symbol) but it doesn't seem to in my case.

Then again with AA disabled I cant get bluetooth tethering to work for mobile data either even though the <--> shows up. Have any of you done any testing with these connection scenarios/sharing data while AA is connected?
[MTCD Android Head Units General] h@wk3y3:
Care to share how you got wireless android auto to work? I've installed versions you suggested but for the life of me I can't get wireless android auto to work!

I have a Pixel 2xl running Android 11....all stock.

Thanks heaps!

Hello someone can help me how to upgrade my android version from 8 to 10 or 9?
[MTCD Android Head Units General] mel0ntek:
I do not have a PX5 model, nor have I gone through the process. However, there's a bunch of people who have in this thread. The search function at the top of this page that allows you to select "this thread" to narrow down the replies to search terms if you want to read through people's experiences/etc.

That said, my understanding is that upgrading Android versions is a bit more involved than OTA updates. It can be done with the factory method, or using Hal9k_'s mod installer (you may have to buy it).

Here is a link to his post on upgrading

Here is a link to his mod installer (he recommends using it instead, it's in his signature)

Best of luck!
[MTCD Android Head Units General] Sylvan151:
We have the same HU. Let me know if you are able to do so as i want to upgrade as well from 8 to 10.
[MTCD Android Head Units General] marchnz:
See my thread detailing ways to upgrade to Android 10 for free.

Also those with incompatible MD725 Bluetooth module, I have located a replacement Android 10 compatible Bluetooth module on Aliexpress

Hi everyone, I wanted to know which MCU version: MTCE_HA for DASAITA is the most recent to be installed, my radio is a PX5 (ex PX3); now I have loaded an MCU: MTCE_HA_V3.67_1. Which is the most recent for DASAITA?
[MTCD Android Head Units General] Sylvan151:
It's 3.69c
[MTCD Android Head Units General] njoule:
Thanks, where can I download this MCU? Is it compatible with PX5 and Android 9 Mod Hal9k?
[MTCD Android Head Units General] Seggszpir:

Hi,

so I tried to set up wireless android auto but didn’t succeed.

It only giving me option to use it with usb.

I have the latest zlink and I tried with Mi 9T

(K20) with android 10.

can someone point for a solution?

Thanks
[MTCD Android Head Units General] Ramias:
If it isn’t one thing it is something else. iOS 14.4 seems to connect more reliably and no longer auto resumes podcasts.

but just tried to have a phone call and the other person could not hear me. Until I switched my phone to speaker phone.
[MTCD Android Head Units General] ruinertt:
I don't know enough about your head unit to tell you exactly what to do. On my Dasaita, I had to forget the hotspot on the head unit, forget bluetooth, and clear the cache for Zlink. At that point, I connected with the USB and started from scratch (BlueTooth) and then it setup the hotspot for me. Now, when I start the car, my phone connects to bluetooth AND the hotspot on the head unit. Android Auto then launches.

I have a Samsung Note phone. I remember that Samsung and Pixel phones were the first granted with the ability to run AA Wirelessly with Android 10...the other phones have to wait until Android 11. Maybe that has changed, but Android 10 and wireless Android Auto is limited support. Then again, this is more mirroring (Zlink) so that requirement might not be needed anyway.
[MTCD Android Head Units General] ruinertt:
I don't know of anyway to manually trigger wireless carplay (like with a button or anyway). It's an app that either connects or it doesn't.
[MTCD Android Head Units General] ruinertt:
Not sure that internet data will pass over bluetooth (maybe?). Setup a hotspot on your phone and have your head unit connect to it. Assuming that your provider allows for tethering, that should be all that you need.
[MTCD Android Head Units General] ruinertt:
Remove the hotspot, remove bluetooth, and clear the cache on the zlink app.

Connect your phone with the USB cable to the head unit and go through the steps. It SHOULD automatically setup the hotspot that will be recognized when your phone connects to its bluetooth....should. Does your phone try to connect to the head unit's hotspot after bluetooth connects? That's a key step.
[MTCD Android Head Units General] majidkorai:
Since I updated the firmware, I am able to connect to android auto wirelessly, it works ok. except that its laggy sometimes. But thats fine.

The issue for me is that now whenever some one calls , the call rings not only on android auto, but also on the headunit itself, since it is connected using bluetooth.

Did anyone of you guys experienced this issue ? Is there any solution to it ?
[MTCD Android Head Units General] talrhv:
mine is also Dasaita PX6 - max6 HU. I'll try what you suggested thanks.
[MTCD Android Head Units General] Bob_Sanders:
Sorry, I haven't got an answer to your question... I'm just curious... is there any advantage to running android auto on an android head unit? I ask merely because I don't understand why AA would be required or even wanted if the head unit can do what your phone can... or is there something I am missing?
[MTCD Android Head Units General] ruinertt:
Cellular data is the main issue. When you are connected via Android Auto (cable or wireless), it basically mirrors your phone. Thus, when you need to use data (Google Maps or Spotify or something of the sort), it uses it much like you would when you browse your phone. Android Auto is basically controlling the apps on your phone and putting them on your head unit. Most people get unlimited data that way.

However, if you want to use native Android (and then use those native apps), then you need to provide a data source for them. If you want to use native Google Maps or YouTube on your head unit (non-Android Auto), you need some type of internet connectivity. That requires you to make a hot-spot on your phone or any other device that can share data. Maybe tether your phone if you can. Most plans cap hot spot/tether data usage, so you have to think about that. Some phone plans don't even have it. Also you have to think about how you need to turn on your phone's hot-spot each time you get into the car and make sure that your head unit connects to it.

Sure, running Android natively is possible (gives you A LOT more freedom), but there are steps that you need to take in order to do so.
[MTCD Android Head Units General] rayaraya:
hellow, sorry if i do repost, i hope not. i have dasaita px6 max 6 android 9 for accord 2007 , it is integrated ac with HU. the problem is the ac doesnt display on the HU. do you know why?

and what is the lastest MCU for mine? where to download? thank you all
[MTCD Android Head Units General] majidkorai:
100% agreed. There is no benefit of using AA other than what you mentioned. Even I think you can do more with the actual os installed on your HU coz its a full fledged android device as compared to AA which is very limited in terms of availability of apps.

Update working great here. ZLink still 4.0.14, and still crashes when clicking Settings (even after clearing data and re-activating ZLink). Same problem past 3 versions though, and AA otherwise works fine.
[MTCD Android Head Units General] ruinertt:
Notice any changes?

The issue that I'm having involves 'dark mode' with my maps and headlights in Android Auto. When I first start my truck, it has auto-sensing headlights that turn on when it is dark/night. However, by default, the maps (and other apps) start in the 'dark mode' even when the headlights are off. It takes my turning the headlights on, then off (manually) for it to go back to 'light mode' with the brighter colors. Then when the headlights come on (auto-sensing) it switches to dark mode like it should.

There was initially an issue with AA and 'dark mode' on the phone itself (which I run) getting confused, but they were supposed to have fixed that. Of course I can go into the Developer Options in AA and permanently set it to light/dark, but I'd rather not do that.
[MTCD Android Head Units General] demetry14:
Are all of the MTCE MCU updates through 3.71d still fully compatible with PX3 and PX5?
[MTCD Android Head Units General] talrhv:
Hi, I didn’t figure how to forget the hotspot on the head unit itself. Can you tell me where in the menu to do that? Thanks.
[MTCD Android Head Units General] Guillermo h:
These updates are official from Dasaita ?. I have directly requested these files from Dasaita and they have given me the one corresponding to December 17, 2020, which of course I already have. Thank you.

Hi guys,

on android 9 I had an option to adjust manually the back view camera ruler with touching the screen and move the lines.

Now on android 10 there is only option to pick ruler number 1,2,3 without adjusting it.

is there a solution for this?

Thanks!
[MTCD Android Head Units General] graycorgi:
Mine still does this. I usually use dark mode so I never paid too much attention but it looks like this is still an issue.
[MTCD Android Head Units General] Guillermo h:
They have answered me from Dasaita:

"Dear, this one is more stable"

; that is, the version of December 17, 2020.
[MTCD Android Head Units General] pakoner:
Credo che il tuo contatto a Dasaita non sia aggiornato. se non ti fidi non installare.

attenzione che aggiorna il bootloader

Mod translation

I think your contact in Dasaita is out of date. if you don't trust it, don't install.

beware it updates the bootloader
[MTCD Android Head Units General] checksum123:
So I was trying the recovery again via OTG, and this time I chose to erase flash first. I started the erase process, but it failed at the end. I tried going back to recovery mode, now it won't let me enter recovery anymore.

Any ideas?

I probably bricked the unit :-(

You need to remove any SD card b4, otherwise the ERASE will fail

[MTCD Android Head Units General] Bob_Sanders:
There is so much crap out there now that has been uploaded, downloaded, side loaded, in between loaded, copied, 'fixed', 'adjusted'.... you don't know what you are actually putting on your machine anymore.

In general, I don't "update" at all unless I have a REAL problem that I can't live with because there seems to be an equal chance with these so-called "updates" to make things

worse

rather than better, but I CERTAINLY WOULDN'T use an update that is not on the official list. Now maybe they are just slow in updating the update list, but those updates (so far) are not official.
[MTCD Android Head Units General] marchnz:
I don't know what you mean by 'not official', it's not like anyone outside of the factories and HCT has access to the source files or modifies these.

I'd agree that people get hung up on bigger version numbers and a ostensible belief that updates are somehow better. Especially MCU updates, which few people understand what the MCU does.

I mostly see complaints after updating and a lack of ability to do anything about bugs.
[MTCD Android Head Units General] marchnz:
Got a hammer?
[MTCD Android Head Units General] Bob_Sanders:
There are modded mcu's/updates ALL over this forum. People extracting this, adding that, modding here and there. Not that I have anything against that mind you. It's all part of the fun for many, but you do need to be careful to check the source on these updates. Certainly no disrespect towards @pakoner in post 3942, but we have no idea where those updates came from, or if they were uploaded properly... maybe they got corrupted... maybe someone made a mistake and those are actually updates for a bosch dishwasher.... who knows. There is no real description or verification that I could find on them, anyway.

People also tend not to be clear and concise on these updates either... like the 600p/720p mix up for example.... but that's more to do with the typical lack of proper instruction set from the Chinese.

Hi guys!

Just installed a couple of days ago my Dasaita MAX 10 on my mx5 MK3. Everything works flawlessy , from what it seems, but I want to update my unit.

Maybe suonds a little bit stupid but I'm unsure on how to update the unit itself.

I just need to put both MCU and the 10.0 HA3_rk3399_10.0 (20210111) inside the same SD card and then select MCU update?

Also, it seems from the thread this is the recent one (for Android 10 )

MCU: 3.71d https://www.sendspace.com/pro/dl/bmo68b

PX6 10.0 HA3_rk3399_10.0 (20210111) https://www.sendspace.com/pro/dl/1q8cpf

It's right?

[MTCD Android Head Units General] Bob_Sanders:
Could be just a misprint. You never know.

I'm sure the community thanks you for the uploaded updates. That said, they are not on the official update list and someone specifically asked if they were "official" because that is not what they were sent when they asked for updates. Just more proof thees "updates" are a disaster with no apparent rhyme/reason to them (no fault of yours) and you need to be careful what you install.

Hi all,

I’m experiencing random disconnects from CarPlay wired and also on wireless.

I have dasaita max6 with zlink.

it is not a software issue to my option because it happened also on android 9 and also on 10 on any zlink version.

does anyone else experiencing this?

Heads up to any that install the 3/24 update: this one was a full wipe on my system. Had to setup again from scratch. One noticeable addition: there seems to be a "Wireless Update" option now listed with System Update / MCU Update. Not sure if this function actually works, however.

I have a 2015 lancer ralliart with rockford amp. Purchased the new 10.2 unit with android 6.0 from the ebay hotaudio-store along with the canbus adapter for 2014+ vehicles.

I setup the unit like shown in various youtube videos. https://youtu.be/v5B9q_Hf8dU

I still do not get any audio. I'm going to flash the firmware update shown in the first post here and try again but am I missing some step here or configuration?

Everything is plugged in that can be plugged in (no wires were soldered or spliced either).

Below is an image of the canbus we were sent. I assume this is the correct one for a 2015 rockford system. I have the 2015 lancer ralliart.

[IMG="canbus"]http://i.imgur.com/HgTdqkY.jpg[/IMG]

Edit: Also, updated the system to the latest version in first post, and used that separate mcu link for 2.41 since i wasn't sure if the mcu was linked separately because the one in the rom zip was valid for this hardware. System update eventually said that the update failed once it fully booted, but i dont think it actually failed. I then flashed the mcu and that seems to have gone through fine, settings shows 2.41_1. Despite all that, still no audio.

Also, with the failed update of the 3/24 system image, my screen now flashes off periodically. Yay. Gonna try and re-flash the image and see if it goes away. It did not clear any of my settings so I assume it really did fail.

edit2: I re-flashed the firmware again (3/24) and it completed. It did not clear any user data though, and didn't ask me to delete the file afterwards. I verified in the settings app that it is running the new firmware. Everything but sound appears to be working. I tried every combination i can think of in that factory can-bus setting screen for #57 but nothing seems to work.

Also, i managed to screw up the touch menu calibration of the screen buttons (not the touch screen itself). How do you recalibrate? The settings screen says to touch the menu buttons (which i do) but it appears to have no effect. Resetting also doesn't put them at any sort of default.

My unit came with no instructions ...is there a manual? Preferrably in english.

Hi guys. Can I use these updates in PX3 board system?
[MTCD Android Head Units General] droc.noles:
See link below - this is what was sent to me. Pretty simplistic, however, and titled for the 5.1.1 version of this head unit.

https://www.sendspace.com/file/kgam8j

---------- Post added at 08:23 AM ---------- Previous post was at 08:05 AM ----------

A few notes that I've seen that possibly stem from the 3/24 update:

Native USB Audio works - no more wild popping clicking short of the occasional stutter when the CPU appears to get pegged. Can't confirm that this is what is happening when these few intermittent stutters occur, but that is what it appears to be. That said, I don't see a direct way to control the volume in software. USB Audio Player can control the hardware volume of my Audioquest Dragonfly, but I have to enable USB Tweak 1 to stabilize audio within this app. As expected, only audio routed directly within Android is sent to USB audio - radio, etc directly from MCU does not route through USB audio.

Bluetooth seems to be somewhat stabilized with Google Smart Lock not enabled for the connection between the stereo and my Pixel

Just an FYI for anyone who may be looking to get USB audio working and / or is having any issues with bluetooth connectivity.
