hello, since the last IOS 15.0.2 update I have Zlink which freezes when connecting Carplay with a total loss of the Carplay function and the stopping of the usb port neither charging the phone nor detection. you have to do a complete reset of the Dasaita and redo the pairing of the iPhone with Zlink to review Carplay before it crashes after 2 connections! Apple is due to release IOS 15.1 tomorrow night hoping it will fix the bug if it comes from the iPhone. And also hoping that Dasaita will post an update soon with Zlink.
[MTCD Android Head Units General] ikerg:
Which version of zlink do you have?
[MTCD Android Head Units General] Ramias:
I have the PX6 from over a year ago that came with Android 9 and I used the tool from a community member here to update it Android 10 and have been using the Max10 firmware for it. I see here Dasaita has newer firmware and has Android 10 now for the PX6 https://www.dasaita.com/community/forum/topic/36770/firmwares. Should I use that now or stick with the Max10 firmware?
[MTCD Android Head Units General] Bob_Sanders:
The old saying:

"If it ain't broke, then don't fix it!"

If something isn't working then you may want to try an update, but if everything is working to your satisfaction, there is no sense in possibly breaking something while updating.
[MTCD Android Head Units General] benoa.h:
I switched to the Telenav Vivid 10 version and I must say that the system works much better for Carplay especially on the start of the workstation where the Carplay connection is done instantly.
[MTCD Android Head Units General] Topper59:
How did you get Vivid 10 installed? I get "assert failed: update_dynamic_partitions" error when I tried to flash it.
[MTCD Android Head Units General] benoa.h:
Try to delete the Update file and put it back on your usb stick to do the manipulation again.

Dropbox

www.dropbox.com
[MTCD Android Head Units General] Topper59:
Yeah I tried that a few times with different sticks, same thing. Were you on MAX10 firmware before?
[MTCD Android Head Units General] ikerg:
You must have an android 10 previously installed to move to vivid ....if not you have to upgrade your recovery partition first to android 10 and then to the desired android 10 based rom
[MTCD Android Head Units General] Topper59:
Yeah I was already on the latest 10 version. I fixed it with ModInstaller by going back to 9, then back to vivid.
[MTCD Android Head Units General] benoa.h:
yes indeed attention I am under android 10.

Hello, i own a dasaita px5 android 8 and i connected tpms original dasaita . After one of sensors was disconnected, i tried to recalibrate it with no success, tried to recalibrate all sensors, but now all shows 0 bar pressure and 50 °C temp.

Is there any video or instructions of how to pair them to show correct information? Thanks
[MTCD Android Head Units General] ionutlup:
Try to change batteries if not working nothing else.

I have downloaded telenav_vivid_rk3399_10.0_ota(20211203) 3 times, and used 3 different flash drives. Everytime I get Error 21 during install. Does anyone have the MD5 checksum so I can compare? Or a fix for this issue?
[MTCD Android Head Units General] ikerg:
From which version are you trying to upgrade?

Did you remove any other usb or sd card except the one containing the upgrade fro the device?

[MTCD Android Head Units General] kebo3473:
Im not sure if this is the right place for my question, but i got help in here once before. I have an issue while using my head unit with Android auto. Sometimes when i get notifications, my volume gets low. I've found that if i hit the Google microphone button, it will fix the volume. In looking for a solution, i found a YouTube video with the same issue. I hope it's ok to post this link. I'm not totally familiar with the rules here , but this is it-

. Any help would be appreciated. Thanks.
[MTCD Android Head Units General] ruinertt:
I have the same issue (Dasaita 10.2" running Android 10) and the only way to bring it back is to hit the microphone/voice button 2x quickly. It's been this way for a long time. At least we can fix it without getting a txt message.
[MTCD Android Head Units General] graycorgi:
Just updated my MAX6/MAX10 to the 20220120 update. ZLink went from 4.0.32 in the December update to 4.0.39 in this January update.

If you use Android Auto, this update completely breaks it (especially wirelessly) if "HD Display" is ON in the ZLink settings. Previously, this was ON and it worked fine. I never could tell a visual difference but Android Auto WILL NOT WORK if this is ON in the 4.0.39 version. Just wasted about an hour troubleshooting that.

Also, if you are like me and have the radio power off (not sleep) after 30 seconds so it does a clean reboot, the bug where ZLink thinks your headlights are off until you turn them off and on again is still there. Still get blinded by bright google maps / waze screens on first boot at night and have to flick my lights off and on to fix it. Mildly irritating and hopefully one day they will fix that.
[MTCD Android Head Units General] ravipe:
Hi guys, I have a PX5 on my BMW X5 E53 currently running MTCE_KGL_V2.80_2 Mar 1 2018. Can you please share can I get a safe update for my device? If you could also point me on the right direction regarding how to update it safely that would also be fantastic. PS: my px have both GPS and SD micro sd slots. Thank you in advance.
[MTCD Android Head Units General] graycorgi:
Another annoying bug that seems to be introduced in the latest update: When I get a phone call, I see the caller's number in the HUD (screen between speedo and tacho) with prompt to press either answer or hang up. If I answer the call, that screen should get dismissed. Instead, it is staying on the screen all the way until I end the call. That blocks half the screen in the HUD. It was not doing this for me before the 20220120 update. Car is a 2014 Nissan Rogue

Edit: Anyone know the best way to report a bug to Dasaita? I posted this to their forum but this one is annoying enough that I'd really like them to fix it by the next update.
[MTCD Android Head Units General] marchnz:
Reseller/dasaita - but they won't care or english with you :)

Another example of leave it if it's not broken on Chinese origin head units.
[MTCD Android Head Units General] graycorgi:
Thanks, I emailed them anyway. Was hoping some of the ZLink bugs were fixed in the new version which is why I updated (something's always broken, so I always gotta try to fix it unfortunately)

In case anyone needs the version without this bug, this is the update from December: https://www.dropbox.com/s/bw8w2a1h7k16e1j/HA3_rk3399_10.0_ota(20211227)升级包.zip?dl=0
[MTCD Android Head Units General] marchnz:
With respect, zlink on an Android headunit, I don't understand, think about a genuine Android auto unit for this use case.
[MTCD Android Head Units General] graycorgi:
I couldn't find any genuine ones that had a 10" display and fit my car with a factory look. ZLink sucks, but the problem I'm having now with the phone call showing on the HUD isn't even a ZLink problem, that's a problem with the Dasaita firmware itself.
[MTCD Android Head Units General] ruinertt:
Good looking out. I have YET to find a solution to the 'headlight/bright map' issue with Android Auto, either. It's been an issue since I can remember (well over a year ago). That includes both zLink and AA updates as well. I think that it has to deal with perhaps my truck's DRLs (Daytime Running Lights?) but I'm not entirely sold on that. It's funny because my headunit will illuminate the 'dark' lights at the bottom, but AA won't change until I turn my lights completely off/on (like you have to do). I've tried all permutations of using the auto/dark/light settings in AA as well. Go figure.
[MTCD Android Head Units General] ruinertt:
Maybe you can try and revert. The latest MCU is what...3.78? I have a Dasaita 10.2" head unit so I am in the same boat. By the way, while using AA, do the callers on the other end have a hard time hearing you while driving?
[MTCD Android Head Units General] graycorgi:
Yeah, but I've been using mcu 3.78 for months now without issue so it isn't the mcu this time. Its a problem with the 20220120 software version for the system, and unfortunately it doesn't let you flash an older version of that.

I've been told my mic sucks, but I was also told that with the factory mic in my car lol. I use the mic in the unit. There is a mic boost option in the MCU which I tried. I was told it still sounds sucky, but louder. I do have a hard time hearing people in my car who call me from an iPhone on speakerphone, for some reason I have to have the volume on 30 and I can still barely hear them if there's road noise. But they can usually hear me fine.
[MTCD Android Head Units General] ruinertt:
Maybe I'll try the on-board mic again. I switched out my external mic a few times and am working with Iris to perhaps replace the chip/mainboard. I dunno. Everything else works well, but people just have a hard time hearing me (sound like a lot of background noise I am told). By the way, I just installed a front cam (it was very easy to do). Paid about $15 for the camera and it is quality. Helps me 'better' park my truck for sure.
[MTCD Android Head Units General] NikosPot:
Hello. I have a PX5 rk3368 - 4GB ram, MTCE with Android 9. I flashed the latest MCU 3.78 from this thread but I am a little confused with the roms. Which rom is the latest and suitable for my unit? Thank you!
[MTCD Android Head Units General] graycorgi:
I rolled back to the december firmware and it was still doing it. I installed the generic HCT7 firmware from here and now it's not doing it anymore. I think i'll just keep using this one, the interface is better than the dasaita HA3 one anyway: https://www.dropbox.com/s/vd8xf4qirre8vw5/HCT7_rk3399_10.0_ota(20211009)升级包.zip?dl=0
[MTCD Android Head Units General] ruinertt:
i switched out my launcher a long time ago. I think that I use the FCC launcher right now (I've been through many). It's not bad.
[MTCD Android Head Units General] gvillo89:
the workaround that I found for the headlights issue (bright map) it's to put the key to accesories let the headunit starts and then start the car (it's like 15 seconds), headlights will light up when I move the key to contact and start the engine. At least for my car. But it is still an annoying bug
[MTCD Android Head Units General] graycorgi:
Good point - I noticed I don't have the problem when I use my remote start and I think that's because it doesnt turn on the headlights.

Hi, could you please send a working link to the BMW K720-Series Update

this one doesn't work anymore thank you very much in advance

PX3 7.1 https://www.sendspace.com/pro/dl/9l5zkf
[MTCD Android Head Units General] ikerg:
Go to dasaita.com. there are published all the firmwares for bmw series units
[MTCD Android Head Units General] drstoms:
Thank you for your answer, but when I enter desaita, I only see sales when I enter bmw px3, nothing is found when I enter the firmware, I have no idea where to find the firmware for the bmw px3. she fell into bootloop, she needs to connect to the power supply outside the car and upload the firmware, but when I connect the cables yellow red to plus and gnd to minus, no signal pops up on the screen. I connected other radios to the power supply and there was no problem and here, however I did not connect, no signal pops up
[MTCD Android Head Units General] drstoms:
I'm sorry, I have already found, I did not know that the firmware is in the forum section. In that case, the only question about connecting to the power supply will be grateful :)
[MTCD Android Head Units General] ikerg:
To connect the unit to a power supply ... Both red and yellow to +12V and black to ground....
[MTCD Android Head Units General] ikerg:
By the record .. i am pretty sure that your unit has a reset pinhole ....by using that you can punt the unit in recovery mode for forcing an update without removing the unit from the dash.
[MTCD Android Head Units General] drstoms:
Thank you very much for any help, i.e. if, outside the car, after connecting to 12v, no signal is displayed, there is no need to combine it, just connect it back to the car? I read somewhere to connect outside the car, all you need is a yellow cable to 12v and a black cable to the gnd, but the gps antenna must be connected. Anyway, thank you very much, I really respect all the help and knowledge and I am extremely grateful :)

Help a newbie please!​

Totally new to all this. I recently factory reset my Dasaita unit, and did some OTA updates (forgot which ones), and never did any flash drive updates (not sure if I need them?). Now when zlink launches, the android auto interface isn't split screen anymore. I'm already engaged with a back-and-forth email with Dasaita, who said they'll send me a zlink update when ready. Still waiting.

Now android auto looks stretched and wastes screen space. Anyone know what's wrong and how to fix?

[MTCD Android Head Units General] rigattoni:
You just may need to wait.
[MTCD Android Head Units General] lomaxxf3:
I read it's a matter of making android auto recognize I have a widescreen, so now I'm wondering if its somewhere in the settings I can't find, or some code I need to change. Other tutorials online are not for zlink.

And thanks. Was looking for more insight as I like understanding things and if I can help myself as a DIYer, why not?
[MTCD Android Head Units General] ikerg:
More recent ROMs (like vivid dated 15/feb/2022) contains zlink 4.0.39
[MTCD Android Head Units General] ikerg:
Dod you have zlink configured to HD? If not go to settings in zlink and scroll down to enable HD
[MTCD Android Head Units General] ikerg:
Dasaita told me that MTCH is for the most recent PX6 motherboard....I assumed that they are not compatible as Dasaita publishes both mcus at the same time (mcte 3.78 & mtch 3.80)...so if I were you stay on mtce.

Anyway...if your unit is working....why tto upgrade?

MCU upgrades rarely add any feature....just includes support for new canbus boxes.
[MTCD Android Head Units General] lomaxxf3:
Thanks! That did the trick. I didnt realize there were more options hidden below the button mapping settings 😅.
[MTCD Android Head Units General] lomaxxf3:
Oh, I heard somewhere certain ROMs are make for certain markets. That doesn't matter? Mine has max10.
[MTCD Android Head Units General] ikerg:
Vivid ROM are made for dasaita units....so completely conpatible. I have an android 11 ROM and I have to check which zlink version is inside
[MTCD Android Head Units General] lomaxxf3:
I couldn't find any responses to this, so I'm wondering if you figured this out?
[MTCD Android Head Units General] lomaxxf3:
Is there a page /thread outlining why to upgrade? And I wouldn't lose my original zlink license?

I like that my software works fine as is now (except for wired AA zlink, which I'll research another day).
[MTCD Android Head Units General] ikerg:
I am.upgrading ROMs (for testing purposes) once or twice per week.....i never lost my license....just enable wifi and it activates automatically.....

Some months ago I was upgrading only the zlink app (it requieres root privileges) but still activated automatically. You must ensure that zlink apk comes from mcte compatible ROMs (zlink hct channel)
[MTCD Android Head Units General] marchnz:
Most of these people don't even know what they own and that they are posting in a forum specific to the MTCD types.
[MTCD Android Head Units General] ikerg:
You are right....
[MTCD Android Head Units General] GruesomeJeans:
Sorry for the delay, no unfortunately I never did find a fix for this. I ended up putting Hal9k on it and played with that for a while. Then sold the car it was in. Before hand I restored it to the factory shipped software and sold the head unit.
[MTCD Android Head Units General] lupastro82:
Hi, I've a max10 and seen now new update (also vivid) and mtch(??) 3.80. Can i try this or is best to remain to mtce mcu 3.78? Ty 🙂
[MTCD Android Head Units General] ikerg:
Mtch is exclusively for mtch MCU (new dasaita boards)....there is no risk on making the mistake of upgrading mtch over a mtce mcu as the upgrade will not succeed.

I have downloaded the HA3_rk3399_9.0_ota(20211023).7z file for my Dasaita V940 unit, but have some questions about it and how to install it.

- Is this the Android 10 system update? My unit currently has Android 9 running the HAL9K v4 mod.

- How do I install it? I have used the 7 Zip program to extract it and ended up with rk3399-ota-eng.hct.zip file which I copied to a USB flash drive. I then inserted the drive into a USB port connected to my unit and started the unit up. I also tried Settings/System/System Update, but nothing happened.

Any help would be appreciated. Thanks.
[MTCD Android Head Units General] Pavel-71:
It has a bad name, try to rename rk3399-ota-eng.hct.zip to update.zip
[MTCD Android Head Units General] giant53:
It is NOT for Android 10. but for android 9 (MAX6)
[MTCD Android Head Units General] Maxvelo:
Tried that, but didn't work.
[MTCD Android Head Units General] Maxvelo:
Yes, I didn't notice where it said Android 9 because the letters were so small. The link for the file I downloaded was listed under V940 which is what I have so maybe Dasaita linked to the wrong file.
[MTCD Android Head Units General] Pavel-71:
Try to reset Hal9k to factory settings first. Or try to update from recovery.
[MTCD Android Head Units General] Maxvelo:
Thanks for your help, but I decided to leave it as it is. I mistakenly thought it was an Android 10 upgrade but as giant53 pointed out, it's Android 9. Since I'm not exactly an expert at this and my unit is working fine as it is, I don't want to risk screwing it up.
[MTCD Android Head Units General] ikerg:
Try to unzip that file and you could find a update.zip inside that is the one to be used
