Hi,

I've just bought new HA2049-V600 unit and I have problems with DVD eject. Dasaita instructed me to update firmware MCU and Update files. It didn't help and additionally I've lost all nice icons and functions. Some of the icons became very small and unreadable, I've lost some of apps (for example bluetooth app) and perfectly configured navigation. The difference between original - factory state functionality and the one after update is dramatical. How can I get back to nice - factory outfit? Is it possible that DVD problems were caused by firmware problems?

regards,

Marcin
[MTCD Android Head Units General] insaini:
Thanks for the prompt replies ikerg and Wout2426! I'll try the MCU update first and then the Android update. One other thing, have you guys found another music app that remembers the last track played (upon boot up) and has the ability to use playlists? I find the native Music app is good, but just missing the playlist functionality.

Friend can you tell me how can I replace this app? I mean how to do autostart this app when I turn on engine? Because as default I have set "music" and I don't know how to replace it.

You don't have to replace anything....

If you have car launcher pro there is a widget to control Power amp...

After waking up unit is ready waiting for a play button push to start from.the song you left (the song starts it does not get the time point i which you left the song)

If you untick the options on car settings to not start the music player when inserting scard...the default music player won't ever start.

.in any case if you don't want the stock music player you can freeze it with titanium.backup (You need root access) to block that app.

So with the stock launcher there is no other way to open power amp auto at the start?

I will unselect this options with auto start stock music app when sd is mounted.

No car solution is aimed on excellent sound quality.

[MTCD Android Head Units General] piyush7243:
Well it's not about a price issue. A software bug which doesn't allow proper usb audio routing is the issue. Apart from that everything is perfect.

If only that bug is fixed, it will be an ultimate solution
[MTCD Android Head Units General] ikerg:
Nobody promised you a usb audio feature, didn't he? So no software bug related to that.

FYI: I also noticed that for a past week device do not go to deep sleep and that in normal sleep mode (Auto Sleep setting) draw minimal power and do not drain Car Battery.
[MTCD Android Head Units General] marchnz:
So the scenario is that you buy a chinese android headunit with pre and audio outs, not android auto. The unit has dedicated codecs and input switching to cater for non-android radio tuner, TV, independent reverse camera AV switching/handling and then state that additional USB audio doesn't work for you, that the headunit audio is - anecdotally "crap", without any real context or supporting info - which is a problem for you because USB audio is not properly supported.

Do I understand right?

If the audio is "crap" what is it about the audio and how have you determined the audio is "crap". How do you see an external USB DAC as improving the audio in comparison to the MTCD DAC? Specifically what source audio is being used, how have you tested and what were the results?
[MTCD Android Head Units General] typos1:
Just do the 7floor sound mod.

Or read the MTCB forum threads about adding usb DACs, the same method used on those unit would probably work on MTCD/E units.

How the hell would that improve the sound quality ? Its more likely to make it worse - Spotify uses lossily compressed sound files.
[MTCD Android Head Units General] hv006:
How did you now the formats or codecs of the sound files he is ussing ?

Spotify is fine for me excellent sound quality a lot better than ussing a stock vw rns 510 headunit
[MTCD Android Head Units General] typos1:
If you use Spotify then you stream from the internet and the codecs used are the codecs that Spotify use for streaming - the user has not control over the codec that Spotify uses.
[MTCD Android Head Units General] hv006:
You can listen offline to the content and download it in extreme quality the quality is fine !
[MTCD Android Head Units General] typos1:
No it is not - if you download it will be mp3 or mp4, these are lossy compression formats and by definition are not very good.

For decent quality you need a lossless format like WAV, FLAC etc.

Where is Android 8.0 for px5?

Who says 4GB Ram needed for Android 8.0?
[MTCD Android Head Units General] silo:
I will add my 2 cents:

The audio QUALITY from my speakers is worse than with factory unit. Also whenever I get with my car to the tunel or underground garage I can hear noises from my cell phone in the speakers (those noises I've heard on radios like 20 years ago with first Cell phones https://www.youtube.com/watch?v=R0O1_FYzbjw ).

It's sooo annoying, that the only solution for that is to mute HU!

I appreciate other stuff I've got with this unit (live maps with traffic, Spotify, Yanosik (antiradar), etc.) but there are sooo many bugs that should be solved if only producers would open source for the unit!

I can see on the XDA that we have huge community of brilliant developers (Xposed, F1x, Grasser, Malysiak), but all they can do is to HACK, not develop, and investigate what's messed with software or hardware.

And what's more strange is that people like Hotaudio and other produces doesn't get it is if the unit will be rock solid steady, the would sell MORE devices than now.

No one except from geeks willing to dig in their car stereo systems!

No one, it isnt "needed".

So far all units with 8 have 4Gb. So far also we cant get 8 running . . yrt

There is something wrong with your unit or the way you have installed it,this is not usual.

The components inside these units are the same as many OEM and aftermarket "named" brand head units.
[MTCD Android Head Units General] silo:
I've bought it from here: https://www.aliexpress.com/item/10-...32807958991.html?spm=a2g0s.9042311.0.0.PXDdHu

This came in Dasaita box, and seems to be legit.

I cannot see why I could "install it wrong" it was almost "plugn play".

I've connected even Canbus "black box" and my steering wheel buttons works, and other stuff like opened doors are displayed properly.

Do you say that this particular unit is broken?

[MTCD Android Head Units General] typos1:
Because none of the MTCD/E or MTCB/C units I have experienced have had sound as bad as youre describing - theyre not the best sound but theyre perfectly decent, with the 7floor audio mod the sound is excellent.

Do you have a factory amp in your car ?
[MTCD Android Head Units General] silo:
Actually I do have Bose amplifier.
[MTCD Android Head Units General] typos1:
I wouldnt mind betting that thats where the problem lies.

Some Bose systems use the speaker wires on the head unit for RCA out- when the amp wire is connected the head unit goes into "Bose mode" and outputs a low level signal via the speaker wires. If youre feeding amplified signal from your head unit to your amp it wont sound good.

What car is it and how is the Bose system implemented ?

It may help if you google "how to install an after market head unit into a (insert your car here) wit Bose" or something.

Hahah...thanks [MENTION=7757496]Al Ferro[/MENTION] for your politeness....

Currently there is no solution.....it seems that only new headunits will come with android 8 from.factory.

Old px5 boards can be updated by using rockchip tools with a nand repartition that currently we can't use with a hardware mod (otg cable and soldering into board)

[MTCD Android Head Units General] typos1:
I m not convinced that an experienced dev cant simply re-partition the ROM for use on older RK3368/PX5s as [MENTION=5092263]Hal9k_[/MENTION] did for Nougat on RK3188/PX3 1Gb units.

Does HA know what revision number the SoM on Oreo units is ? I ask because the 4Gb RAM soMs are a later revision to the 2Gb RAM SoMs and it may be that owners of the later 4Gb units can upgrade to Oreo without re-partitioning.

---------- Post added at 10:54 PM ---------- Previous post was at 10:42 PM ----------

I think Mazdas use the type of Bose system that I was talking about, although I ve not seen or had any experience of one that late.

You could try a lead that has RCAs one end and a DIN speaker plug the other like this :

https://www.ebay.co.uk/itm/Autolead...hash=item48a05e55f1:m:ms_CypA7Kv9rQbb9Y7Nclag

and connect the RCA end to your head unit. It has female RCAs and so does your head unit so youd need some female to female adapters, you would also have to cut the speaker plug off of the DIN end as you only ned this not the other DIN plug, assuming your Mazda has a DIN plug.

If it doesnt it may have one like this :

https://www.ebay.co.uk/itm/Honda-Ac...679054?hash=item56a7c1bbce:g:5TEAAOSwJ-5aSP1k

Which you could use directly or just remove the RCA leads from the plug and put them on your plug.

You can also buy adapter boxes but they simply "un-amplify" the signal and are bit crude, the RCA solution is the best for sound quality.
[MTCD Android Head Units General] iwl:
If you can boot something, which you do, you can repartition and don't need hardware mods.

The nand is just a blockdevice if you can write to it partitions you can also rewrite the partition table, thats just the first block or some other.

The px5 ist quite new and they never got the 6.0 rom stable, so why they don't just deploy 8.0 for all devices.

If they have no programmers to make a suitable rom why they don't opensource theyr rom and specs and let the community do. Otherwise every honest person must warn everybody to buy that crab.

Can we use the Witson 4GB PX5 board for upgrade in a Dasaita unit?

Yes and its not a Witson SoM, its an HCT SoM, Witson just sell it.

Rockchip tools/rkbatchtools/androidtool requires a .IMG file, the Oreo image file we have is an OTA/ZIP upgrade. Suspect that the upgrade.zip may not be supported by the current PX5 MM marshmallow recovery.

Although I have not yet tried to apply from PX5 MM recovery as are on vacation.

Interesting.. there was mention that all manufacturer's releasing new devices must use the latest version of Android. Also that the new standard is the dual partition A& B .

Here are my reasons:

1. I'm a Android Developer and would like to have newest system to test my app and customization I've already made to existing apps and tested on 4.4.4, 5.1.1, 6.0.1

2. I'm developing hardware 10 band EQ with Auto Gain designed for amplifier Flexiwatt25 (Vertical) AMP chip that is in 99% of devices and made it controlled from Android app (DIY price is less than 20USD)

3. I'm developing NFC reader App that will automatically make connection to HU, execute commands and presets (Mirror link, Internet tethering, start playback, Driver detection, ...) Joying already supply NFC tag with devices, but it is crude design

4. I'm customizing iGO navigation app to better integrate into HU and support Voice search, ...

5. At time of purchase 1.5 months ago They confirmed me that my 4GB/32GB PX5 will support Oreo 8.0 and thus I purchased 2 Devices cca 700 EUR

Also I've talked with HU manufacturer and ATM not willing to disclose talk, but I'm really thinking to make really bad review and video and open public page ti educate and discourage future buyers. I'm backed with 15+ years of experience and 100k+ active users of my app. Also for now I'll withdraw all suggestions/schematics/apps and hardware upgrades that I made till date in the protest for not listening their users and actively promote DO NOT BUY.

Also as a protest I'm planning to start my own DIY project of making 2DIN Universal HU as the parts price for DIY are less than <100 USD if you buy them separately.

HA5268-V600 not booting

Hello HotAudio, Hello everybody.

I'm new on this forum so please tell me if I post in the right post or not !

I've bought Dasaita HA5268-V600 for VW Polo 1 month ago. The seller (aliexpress . com/store/439394) does not want to help and does not reply to my messages. I thus strongly not recommend that person ...

Anyway I'm trying to get help with good people :)

The device will not even boot. I've plugged it directly on the car connector in place of the old player (which works very well), but the new one won't work.

That video shows the old (which works) and the new (which does not work) : https:// __ drive.google.com /open?id=1DGdoTC9XnxLBb5_Iq7cdhfhkrvboNF5o
