Thank you. I eventually got this to work with a different keyboard.

---------- Post added at 02:59 AM ---------- Previous post was at 02:51 AM ----------

You are correct. However, to get it to work the first time, I had to put the MCU update on the GPS SDcard, initiate the update, it rebooted into the recovery screen, navigate the menu with a keyboard and select MCU update, reboot as normal. Subsequent updates worked off a USB flash drive and completed automatically as you described.

Thanks for your help.

I tried everything including paper clips, pins, thin wire, thick wire... straight and bent (to reach further around inside the hole. Still no luck finding the button. Eventually achieved the update using a keyboard but it would still be good to locate the button incase I need it in future.

Out of curiosity and for completeness, I went as far as trying the "mic" hole just incase the labelling was reversed. No luck.

I eventually completed the update successfully but it didn't fix the bluetooth issue.

Hello! I just updated MCU to v2.88 and system to 20180201 on a 2GB Ram PX5. Has anybody noticed issues with sound? Somehow my sound seems muffled? I'm not sure how to explain it but when I skip music there is a momentary increase in volume then reverts back to the muffled sound. I may have to retune my amplifier?
[MTCD Android Head Units General] finkeo:
What MCU version were you on before the update? How does it sound with phone calls? What source are you using for music? Try something other than bluetooth and unpair all bluetooth devices just to see if it makes a difference.

My unit has digital/electronic noise whenever there is audio playing. The noise is only present when my phone (or any phone) is paired with bluetooth and some/any audio source is active. It happens with usb audio, radio and phone. It stops as soon as the phone is unpaired/bluetooth turned off or music is paused. It also stops briefly between music tracks. Maybe it is a similar issue. This happened on the original v2.83 and on v2.88. I might try some older versions.

Dasaita V600 unable to boot from SD Card

I have a PX5 2GB HU that I'm trying to upgrade from Android 6.0.1 to Oreo.

I've created a bootable SD card following Malaysk steps, but when i inserted the SD Card into the GPS slot, the HU does not boot from the card. In fact it just continued the normal boot up as usual.

Am I missing something?
[MTCD Android Head Units General] LnX:
Hi! I was on 2.59 MCU before the update. Phone calls seem the same. I've tested today with different sources just to check ... music from USB and playing it on 2 different players seem the same. I first noticed this on Spotify so I thought it might be because I'm streaming. I've tried turning off bluetooth also and it was still the same.

This noise you mentioned is it like a white noise? I get that when making calls and it happens before the phone rings or before Siri replies through the bluetooth. Basically when Siri replies the head unit imitates a call and my screen has a green red button. The white noise starts a few seconds before Siri replies and turns off when it's done. I think that's normal?
[MTCD Android Head Units General] typos1:
Its as though the BT thinks its streaming a phone call rather than streaming media.
[MTCD Android Head Units General] finkeo:
The noise I hear is like a buzzing and beeping sound, a bit like the sound of an old dial up modem connecting.
[MTCD Android Head Units General] Clandaries:
This is the sound from the smartphone when it is near an radio :)

Try to put it away from the radio.

Regards
[MTCD Android Head Units General] finkeo:
I don't think it is. The noise is still there if I move the phone away, even outside the car. The noise stops if I unpair the phone and head unit, even if the bluetooth is still on.
[MTCD Android Head Units General] maus05:
Can anyone provide the official changelog?
[MTCD Android Head Units General] suspenders715:
If you are getting sound just by having the Bluetooth on then you could be getting interference from something in the unit. Some people have had issues because many of these units have a shared Bluetooth and wifi chip. Some people had success in opening the unit and adding an external wifi antenna to try and separate things. Not sure if this helps or not.
[MTCD Android Head Units General] finkeo:
Thanks for the suggestion but it's already got an external wi-fi antenna. It's really wierd. It only makes the noise while a phone is paired AND audio from ANY source is playing. I can have the phone beside the unit, with bluetooth turned on but not paired with the unit, and play music from a usb flash drive without any noise. Then, if I pair the phone and unit, the noise starts when I start playing the music again. It stops if I pause the music and in the gaps between songs. It's only there while something is being output.
[MTCD Android Head Units General] Hkw84:
For my unit, I noticed most of my noise goes away when I turn off wifi on the headunit.
[MTCD Android Head Units General] Toto1365:
Unfortunately, there is no changelog, I have already asked myself at Dasaita and they could not provide me with a changelog, because the firmware is created at HCT.
[MTCD Android Head Units General] typos1:
Its not quite right to say that this issue has been sorted by adding an external wifi antenna, [MENTION=3269594]suspenders715[/MENTION], youve got that a bit confused. The problem can be on some units with dual wifi/BT chips only have one antenna instead of 2, the solution is not to add an external wifi antenna - most units have them now - its to add an internal antenna so the wifi and BT parts of the chip have theyre own antennas, there will be an unused antenna port near the combined wifi/BT chip if this is the case, but some units have separate wifi and BT chips, so this may or may not be [MENTION=9304898]finkeo[/MENTION]'s problem.
[MTCD Android Head Units General] finkeo:

No, your unit is RK3188/PX5, this thread is about RK3368/PX5 units.

[MTCD Android Head Units General] Trigeek2006:
Thanks Wranglerestyle, when I was on golden UI, my canbus setting was on #37 and all was good. I got good controls from the steering wheel. When I upgraded to blue UI, #37 does not work anymore. Tried #10 also but didn't work too. My ride is Nissan Qashqai 2017. Thus, thinking of going back to the golden UI. Current MCU is on 2.88. I did not record what was my golden UI MCU version. Any help appreciated. Thanks.
[MTCD Android Head Units General] ikerg:
Malfunctioning of canbus is not due to android image Rom

Does your canbus box other functionality apart of swc?

(Door open warning/conditioning air/...)

Did you try if canbus is working properly?

If not...can you check the wires if any connector is loose?

If everything is correct....revert to older mcu software...not android image rom.

When golden UI mcu versions were below to 2.88

So...you have upgraded both mcu and android image versions

Are you sure you are under the same mcu manufacturer?

If your unit is Dasaita and it came with HA mcu...do you have now a HA mcu version as well?

Thanks ikerg, I managed to find the fault of the lost steering control when I upgraded it to the Blue UI. Coincidentally, the can bus cable that comes with the Daisata set was slightly loose. It can be yanked left and right and yet not unclick. Pin 11 of the plug which is the canbus tx must have been not connecting well. It is all good now. Thanks to all who chipped in to assist.

System Update is not recognized?

Hi, I'm trying to update the system with the newest update, but I notice the file that's linked is a .7z zipped file (Blue UI HA_PX5_8.0_ota(20180717). I have tried unzipping and it gives me a update.zip file next. Then I unzipped the update.zip file and it exposes me to a folder. I then go ahead and make that folder a .dmg and then convert that into an .img. When I get it to my radio unit, I click system update, but nothing happens when I do.

Is there a possibility that the uploader could just upload the .img files instead of a .7z file inside of a .zip file, etc? I think some where along that whole process I might be messing something up, but I've re-done the .img file process 5 times and my system won't pick up the file in my usb drive.

My radio unit is currently on Blue UI HA_PX5_8.0_ota(20180516

Thanks, I watched a youtube video indicating that the update.zip had to be an .img file. Everything worked great!

On another note, the hotspot functionality doesn't work for some reason. I've been able to connect to my wifi at home, but when I try to connect to my iphone's hotspot, I get as far as authenticating... and it never ends up connecting to my hotspot. I've seen this with the previous system firmware as well as the one that I just installed today. Is there a way to get the hotspot working correctly that I'm not aware of?

Alfa Romeo 159 use Can-Bus impulses for steering wheel commands (not resistive), nothing related to MCU (need to be "original" XRC). You need check canbus options on HU factory settings then use Key studio. Give a try.

bluetooth issue in my dasaita HA2115-V840

i have Bluetooth issue in my dasaita android 8 unit installed in Honda crv 2012 (MCU :MTCE V2.75 and Firmware :Blue UI HA_PX5_8.0_ota(20180705))

1- interrupting sound when running any video on connected iPhone

2-sometimes phone call stuck on screen although call ended in mobile so need to switch off unit to end call

3-need to click 3 times on answer call button in car to accept call

4-sometimes sound become interrupting during phone call and other person did not here me

5-other times failed to connect to unit at all and when check Bluetooth setting in screen , i found default name and password became blank

Tried different firmware and MCU

*some solved problem temporary and after 5-6 days issues appeared again

*others maintain same problem after installation

All other unit function except Bluetooth are in perfect condition

Should i assign specific firmware version to specific mcu one???

IS it a software problem or hardware problem ?????

[MTCD Android Head Units General] finkeo:
Thanks to everyone who replied and tried to help with these issues. I thought I should return and give an update since I have fixed both issues.

To fix the bluetooth noise, Dasaita/HA sent me a replacement module. I removed the old one and soldered the new one in it's place. The noise is gone.

Regarding the reset button, I discovered that the PCB holding it and the leds for the panel buttons was dislodged. After putting it back in place the reset button now works and I can get into recovery mode.
[MTCD Android Head Units General] iRcKenny:
First you need check if your HU have a canbus decoder box (its a brown box connect to main harness), if not present you need buy that.

To access factory setting tap on "fatcory settings" on HU main settings section; enter password "126" without "" then check your canbus on Canbus section and for Key Study simple use the right section.

P.S.: Making mess on factory setting maybe result in unusable unit, modify at your risk!
