[MTCD Android Head Units General] BluPhant:
Couple small issues with this HU- My goal is to have my music library with me in the car, to that end I salvaged a 250g SSD drive from a laptop and put it in an enclosure and mounted it in the glovebox. My library is about half that size. The drive is connected to the head unit via usb.

When starting the car, if Poweramp was active when I turned the car off, it attempts to go back to the last song playing, which hasn't yet been mounted (as it takes Android a few seconds, say nominally 15) to get everything sorted. It appears that once it tries a couple times, Poweramp then goes through and does a full library rescan (which takes some time with my library). In the interim, everything appears to be gone (artist/album/etc info all "nothing to see here".)

I found the setting for "don't scan automatically" and have ticked that, and will be experimenting going forward, but I can't be the first person to have this issue, and was wondering what other folks have done

One of the other things I want to do with the Xtrons is stream content directly from my phone; mostly audiobooks. This may or may not be related to Poweramp (to test I'd have to uninstall it I guess) but I'll detail it to see if anyone has some sage advice for me. The Xtrons has an A2DP app which handles the audio streaming inbound from other devices. This app launches for a moment, and then goes away. Sometimes it plays a second or two of the most recent Poweramp track, other times it just closes. My phone is connected for sure, and the Xtrons is pulling the title/etc info from my audiobook, but it never plays. It almost appears to me to be some kind of contention between the A2DP app and Poweramp. I've gone into settings and disabled all the bluetooth controls (at this point I don't need them) to no avail.

Any help with either of these issues would be appreciated!

Thanks-

-Blu

I have the same problem with poweramp, let me know if you find a solution :(
[MTCD Android Head Units General] djshotty:
I've got 850 or thereabouts 320kbps 48000Hz joint stereo MP3s in the head unit's internal NAND storage, using JetAudio to play them, and having no issues. I used MX Player on my previous unit, in a similar way to what I am with my Xtrons now and yep, no issues there either. Having only ever evaluated PowerAmp on my Galaxy S6 and hating it, I wonder if your issues might be with PowerAmp itself. Have you tried a different player app.? Also, what does the stock ROM's player think of your library? Does it rescan every time?

The new MCU is 2.93 found here:

https://docviewer.yandex.ru/view/0/...mcmFtZSI6ZmFsc2UsInRzIjoxNTM4NTYyMTE1NzY3fQ==

Has anyone in this thread tried it yet? I'm apprehensive to flash it as my unit is working, wonder what improvements it might bring?
[MTCD Android Head Units General] bogdi1988:
I might try it later today. I read on another forum something related to improved audio. A different amp app is required as well though. https://www.audi-sport.net/xf/threads/xtrons-free-sound-update-dramatic-improvement.378941/

---------- Post added at 02:19 PM ---------- Previous post was at 02:08 PM ----------

I might have found an update to the Android build as well. I'll try it later today and update you guys. If it works well, I'll share the link here.
[MTCD Android Head Units General] skezza:
I'd really appreciate you letting us know :)
[MTCD Android Head Units General] bogdi1988:
Both worked great! Gimme a few minutes to upload the files.
[MTCD Android Head Units General] bogdi1988:
Here's a screenshot of the new versions.

Just got a new car and looking round..

Would these comments still hold true now?

It's tuff wading through the posts and internet..trying to find out which one is worth the $$$..

My last Joy is still working but went with the car and of course it's stuck on 4.4 as never moved it up to 5.1.

But dam had some fun with it..

So.. verdict anyone?..

The 4g and 32gig make these worth looking at..
[MTCD Android Head Units General] Oberbergler:
Yes, it's still my best HU I've ever had. If I would upgrade now, it would be definitely again a Xtrons :)
[MTCD Android Head Units General] bogdi1988:
Agreed as well ?
[MTCD Android Head Units General] skezza:
Any noticeable benefits/improvements?
[MTCD Android Head Units General] bogdi1988:
I haven't had enough time to check that. I did a quick functionality test and it worked well.
[MTCD Android Head Units General] skezza:
I'm thinking sound quality, maybe a solid beeper when reversing etc?
[MTCD Android Head Units General] Flemischguy:
Solved!
[MTCD Android Head Units General] bogdi1988:
I think the audio sounded a bit more crisp
[MTCD Android Head Units General] bogdi1988:
The sound seems a lot better. The highs are really crisp. So overall I would say it was worth the upgrade ?
[MTCD Android Head Units General] skezza:
Is that the modified MCU?
[MTCD Android Head Units General] bogdi1988:
I think it was stock MCU. Just updated one.
[MTCD Android Head Units General] bogdi1988:
I will test the sound patched one tomorrow and update here.

---------- Post added at 06:56 AM ---------- Previous post was at 06:42 AM ----------

Well, I lied ?. Went ahead and tested right now. The bass sounds quite good and clean after the sound mod. I included the files in my Google Drive link. There's the latest MCU, latest Android build and the sound patched MCU. Overall, kick ass ?
[MTCD Android Head Units General] eDooM85:
Is the reverse camera equiped with sensors, mine doesn't do any sound when reversing
[MTCD Android Head Units General] skezza:
No, but the OEM sensors hook into the system via canbus, but there is no solid beep apparently :-\
[MTCD Android Head Units General] DAVIZINHO:
Hello,

Sorry for my post if is stupid, but is my frist radio and im testing in home with a pc power supply and after some test i install in my car.

Now I have 1 (maybe) stupid question:

1.- how can I upgrade the rom or the MCU. I must put the 7zip or the rar in a sd card? or in a specific folder? uncompresed?

EDIT: in my un-editted post i make 2 more questions, but i solved :)

thanks a lot!
[MTCD Android Head Units General] bogdi1988:
Unpack the MCU file and put it on the root of the USB drive. The ROM update keep as a zip and don't unpack. Same thing, place on root of USB. Plug USB drive in stereo. Doesn't matter which plug. Go to settings, and in one of the menus you'll find the update MCU and update ROM options. From there it's a straight shot.
[MTCD Android Head Units General] naplesbill:
Here is the pic of the 10.1 as promised.

Also, to get to developer options you have to install an app from Google Play.View attachment 4407029
[MTCD Android Head Units General] tabocaw:
I tried that and it force closes itself. I also tried kingoroot and does the same thing. Maybe a factory reset is needed.
[MTCD Android Head Units General] bavarianblessed:
How is the start up time on this unit?
[MTCD Android Head Units General] tabocaw:
About 45 sec to a minute for cold boot and 1 to 2 seconds forbsleep mode. It's only done a cold boot twice. Haven't had it since first start up and after I did a factory reset.
[MTCD Android Head Units General] Chetski:
Thanks for posting the picture. Is the display adjustable vertically?
[MTCD Android Head Units General] naplesbill:
It tilts forward and back.
[MTCD Android Head Units General] Chetski:
Ok, this is very helpful, but if you would be so kind to tell me if the bottom of the display is flush with the bottom of the Head Unit. In other words if you set the HU on a table is the display also sitting on the table. I need the Display to not go much below the HU. Thanks!
[MTCD Android Head Units General] naplesbill:
it only slightly overhangs on the bottom side. Most of the overhang is at the top. It doesn't sit completely flat with the screen installed though
[MTCD Android Head Units General] Chetski:
Thank you! Just to clarify "slightly" would you say less than 1/2" (12mm) or even better 1/4" (6mm) below the deck. Any more than 1/2" and it will block my AC controls somewhat.

I might be able to tilt the HU downward in the dash to help if needed. I'm really looking forward to this upgrade in my Ford Excursion.:fingers-crossed:
[MTCD Android Head Units General] naplesbill:
If you find that unit on eBay, it should have a picture showing all the dimensions, including the upper and lower overhangs. Not sure why they don't have that info on Xtrons web site.
[MTCD Android Head Units General] tedkord:
Does it receive HD Radio? Thanks for any help.
[MTCD Android Head Units General] bogdi1988:
I don't think any of the Android units support HD radio
[MTCD Android Head Units General] Paul2482:
Can any one tell me if the AV out shows everthing the head unit shows, want to show Sat nav in the headrests
[MTCD Android Head Units General] pac.eden:
Dasaita has the same model hardware and design wise, but they said they updated Bluetooth and amp (TDA7850, 2x50 W), which is supposed to improve sound quality. I am getting conflicted information.

Xtrons says that TDA7850 is older and that TDA7851L is newer, Dasaita says the contrary + that TDA7850 is mkre expensive...and I would really like to come to the bottom of this. Units also differ in rear heat sink design - so which unit is better overall?

You can get both units with Android 8.0

Dasaita V600:

http://s.aliexpress.com/BnyMfYve?fromSns=Copy
[MTCD Android Head Units General] bogdi1988:
7850 is newer and a bit more powerful

---------- Post added at 06:09 PM ---------- Previous post was at 06:07 PM ----------

The problem is that Dasaita is still 2GB while Xtrons is 4GB
[MTCD Android Head Units General] naplesbill:
If you look up the datasheets for both modules, the TDA7850 has been around longer.

The first datasheet revision for the TDA7850 is from 2006. The first datasheet revision for the TDA7851L is 2011.
[MTCD Android Head Units General] Flemischguy:
The 7850 is indeed older, Version 6 http://www.st.com/content/st_com/en...-class-ab-audio-power-amplifiers/tda7850.html

the 7851F Version 4.0 http://www.st.com/content/st_com/en...class-ab-audio-power-amplifiers/tda7851f.html

The 7851L Version 3.1 http://www.st.com/content/st_com/en...class-ab-audio-power-amplifiers/tda7851l.html

All the MOSFET class AB audio power amplifiers above, are on active
[MTCD Android Head Units General] bogdi1988:
You are correct. I was looking at a newer datasheet for the 7850. It does seem to have more power though?
[MTCD Android Head Units General] naplesbill:
It does seem to have a marginal amount of increased power. I doubt that 2 watts per channel will be at all noticeable though.

I always use an external amp anyway though.
[MTCD Android Head Units General] bogdi1988:
For me, the killer is still the 4GB of RAM. I messaged Joying as a curiosity and they said they can offer me a 4GB unit but it would be still Android 6.0 and their TDA7388 amp chip which I think is a really crappy amp chip vs the Xtrons or Dasaita...
[MTCD Android Head Units General] xxxdauser:
I was having severe Bluetooth quality issues such as distortion and cracking. I reached out to xtrons and they provided me with the link to the newest firmware files: (replace xx with tt as I’m a new user and cannot post URLs) hxxps://1drv.ms/u/s!AjrY0uqbW_kBklRpld7xEiS8BqW-

After installation of both the MCU and System Update my Bluetooth sound is 100% better and does not crack or distort. I am having an issue with audio from calls. When making a call from the head unit I can dial out and receive calls but I get no audio. If anyone can help I would greatly appreciate it. my Bluetooth is using driver WQ_BC8–I have tried WQ_BC6 as well without luck.

Update: Xtrons has instructed me to update via the Recovery Mode for the software update first followed by the mcu update once booted into Oreo in the update settings. This will result in me losing all my data and starting fresh but I am happy to attempt if it means all functions will operate properly. Also I fixed my link to the latest update from Xtrons (20180920).
[MTCD Android Head Units General] bogdi1988:
What's the MCU version? And looks like One Drive is down? ?
[MTCD Android Head Units General] skezza:
That's not great..... don't really want to update now :D
[MTCD Android Head Units General] xxxdauser:

[MTCD Android Head Units General] dorz:
Hi all, just bought this head unit and it seems amazing! i have tried google maps, installed spotify, got Torque running with my bluetooth OBD reader, and audio sounds clear.

the day after i installed it i started having it freeze at random, it would be playing a song in spotify or on the radio and then randomly stop playing, and flash up with the X logo (Xtrons). it would hang like that for a while, sometimes i would try and reset it and other times it would automatically reboot, but then it displays an error message saying cant load android system, your data may be corrupt. try again or factory data reset. none of the buttons appear to work, however i have read somewhere plugging in a USB keyboard will work. has anyone seen this before? i have included an image of the error message below. note this is straight out of the box with 1 app added, i signed in to google, and have connected 2 bluetooth devices. it appears to do it about 30 seconds after it powers up now.

sorry i had to put xx in the link, it wont even let me attach image as a IMG to the post for some reason.
[MTCD Android Head Units General] xxxdauser:
Hi,

Use a paper clip and press the reset button to change option and long press to select option. Hope that helps.
[MTCD Android Head Units General] bogdi1988:
So that MCU and ROM update from Xtrons are the exact same files I liked here a few days ago ?

Oh and you should try out the sound modified MCU... It sounds better
[MTCD Android Head Units General] xxxdauser:
Thank you for the recommendation! I accessed your google drive share and was wondering if you were to start from scratch, would you simply update the software in recovery mode then update with the modified mcu once booted into the os?
[MTCD Android Head Units General] bogdi1988:
Just do MCU from OS
[MTCD Android Head Units General] xxxdauser:
Update: Everything works for bluetooth audio via A2DP and making calls. I made the mistake of changing the bluetooth driver in the "factory settings" to WQ_BC6 when it is supposed to be SD_BC6 (in my case anyway). I'm keeping it OEM with the mcu and software update from Xtrons in the link above.

Issue: Anyone else notice that the bluetooth audio via A2DP is different from driver SD_BC6 vs WQ_BC6? WQ_BC6 sounds wayyyy better than SD_BC6, but I cannot get phone call audio. This is super lame.
[MTCD Android Head Units General] dorz:
Hey xxxdauser,

The first few times it came up i didnt even have a sd card in it, and i am not trying to do an update! Wondering if i should just to see i f it goes away, or just do a factory reset?
[MTCD Android Head Units General] dorz:
update on my issue, not sure what the cause was. i did a factory reset, wiped all data and started again. it appears to have fixed it. i noticed when i factory reset it that torque was no longer installed, however i have previously bought it anyway so that wasn't an issue. i have also since updated the unit using the packages from bogdi1988, which updated perfectly fine and i havent had any further issues. loving this head unit!
[MTCD Android Head Units General] padave12:
Does anybody know about kunfine android head units - and how they compare to the Xtrons? This is the only HU with Android 8.0, Octacore and 4Gb that has a custom fit for my current vehicle. It comes pre-equipped with steering wheel controls - which is also important.
[MTCD Android Head Units General] lupix7:
Xtrons te706pl. Is there an option for when reverse gear is inserted to keep the radio audio on?

i connect a 3g modem to the usb port. It works if i plug in with the radio power on.

If the usb 3g stick is connected and then power on the radio, the 3g dont work.

After this i unplug, then plug and works.

any idea?

thanks!

hello.

I want to launch some apps on startup (dvr recorder, spotify, radardroid, maps, etc...) its posible to select a list of apps to startup automatically on startup?

thanks
[MTCD Android Head Units General] bogdi1988:
I think you might be able to use something like IFTT and set that up
[MTCD Android Head Units General] DAVIZINHO:
i think tasker maybe the solution but i dont find the option "on boot" to launch the list of apps :(
[MTCD Android Head Units General] eDooM85:
The problem with tasker it's that forgets the accesibility setting and no longer works as intended
[MTCD Android Head Units General] DAVIZINHO:
with tasker i can launch all the apps that i want in the start of the unit. this was solved :)

I have 2 problems now:

- How can i reboot android????, its stupid but i cant find the option to force a shutdown and start again :( If i push the power button the unit fall into sleep mode, not shutdown

- I use a app for speedcams in backgroud (radardroid) but i listen it very low. i force in the app the volume to top but it still low. is posible to force more volume for apps?

Anyone knows Eunavi?

It looks like exactly the same as Xtrons but much more cheaper:

https://es.aliexpress.com/store/pro...r-radio-universal-GPS/410439_32891343573.html

Edit:

They also say it has IPS screen, but it's more cheaper.

How it can be possible?
[MTCD Android Head Units General] Jkteam:
yes in the settings. mine is at volume -2
[MTCD Android Head Units General] jtrosky:
I bought both a GM-specifc Hizpo-branded unit and a GM-specific Eonon-branded unit (both 7"). Both had the exact same specs, but the Hizpo was about $75 cheaper and advertised an IPS screen (whereas the Eonon had a TN screen). When I compared the two side-by-side, the screens were *exactly* the same. Same brightness and exact same color/brightness-shift issues when viewed from an angle.

Long story short - the Hizpo unit that claimed to have an IPS screen was just plain false. It really had a TN screen even though they specifically advertised it as an IPS screen (and advertised it *boldly*).

You just can't trust what these companies advertise. "If it sounds too good to be true, it probably is". :)

Also - most of these units come from the same manufacturer - just sold by different companies that slap their name on them and resell them - which is why so many of them look exactly the same...
[MTCD Android Head Units General] Sivioke:
Just ordered this unit... can any help me understand what the best harness would be to connect to a 2007 chevy impala ss and retain steering wheel controls?

I'm comfortable with soldering however I'm quite the noob when it comes to car audio
[MTCD Android Head Units General] jtrosky:
They sell a Chevy-specific version that comes with the harness and CANBUS adapter. That would have been the way to go. Plug-and-play and OEM-look (you don't need any fitment adapters or anything like you will with a "generic" version)...

Is there any particular reason why you didn't buy the Chevy-specific version (which is compatible with the Impala)?
[MTCD Android Head Units General] RogerClark:
It depends on how the steering controls work on that car.

The unit can be controlled by either CAN bus on newer cars, or the 1 or 2 wire control system on older cars.

I found on my old Subaru that there was just a single wire which was connected to all 6 buttons on the steering wheel, so I just had to solder that wire to the first of the 2 wheel control input wires.

The second wheel control input wire, was left not connected to anything.

You then just need to go into the Settings -> Car screen and get the unit to learn what each button on your steering wheel does - by pressing each button, (one at a time) and then configuring the button to an action in that screen in the settings.

Unfortunately, it its not a very flexible system.. You can only configure it to do the options in the settings screen, and AFIK you can't use external programs
[MTCD Android Head Units General] Sivioke:
Thanks for the reply... i wasn't aware of the harness... I bought the unit off of ebay (impulse/last minute change of heart. Was going to go w/ Pioneer then some youtube videos swayed me to the xtron) so I didn't quite know what i was getting into..

Anyway do you have an appropriate link for what i need?
[MTCD Android Head Units General] jtrosky:
The Impala is a CANBUS system.

Here is a link to the Chevy-specific version of the Xtrons unit:

http://xtrons.com/pb78jccp-android-...ustom-fit-for-chevrolet-buick-gmc-hummer.html

Unfortunately, I have no idea how to get the generic version working with the Impala. At the very least, you are going to need a physical fitment adapter (GM radio is a little bigger than standard 2DIN), a custom harness for the radio and some sort of CANBUS module with speaker (needed for turn-signal sounds, warning chimes, steering-wheel controls, reverse-detection, headlight-on detection, etc). I'm not sure if you need to use one that is specific to the Xtrons unit or if a "standard" retail CANBUS adapter will work with the Xtrons. It's not going to be easy to get a generic 2DIN unit to fully integrate with your Impala...

I would reach out to Xtrons and get their input.
[MTCD Android Head Units General] naplesbill:
It appears that this is what is needed for a 2007 Impala SS to retain steering controls and install an aftermarket radio:

https://www.sonicelectronix.com/ite...-and-Radio-Replacement-Interface-DKGM-49.html
[MTCD Android Head Units General] jtrosky:
What I don't know is if these Android units will work with any CANBUS module (such as the one linked above - there are many different types). I know that there are a few different GM-related options in the Factory Menu CANBUS setting - just not sure if one of those will work with this type of CANBUS adapter (vs. the CANBUS adapter that comes with the GM-specific Xtrons radio).

Then again, maybe they all follow some "standard" and are interchangable?
[MTCD Android Head Units General] Jkteam:
I shop that was working on my car broke the gps cable on that unit. I dont' remeber that plug of the gps that it came with. Can someone help. Falka?
[MTCD Android Head Units General] Dev0882:
I managed to do the same thing when pushing the unit into the dash, the cables were so tight the weakest part broke which was the GPS connector.

This site won’t let me post links, but to fix I used a FAKRA MX-73403-6282 connector (eBay item 192334571540) and a longer Wi-Fi cable (eBay item 112462513121) and soldered it to the board in place of the existing.

The FAKRA connector now attaches to the other end and tucks safely behind the unit with the other wires and so no longer sticks out the back.
[MTCD Android Head Units General] Eventer_:
How good is the radio and wifi reception?

Better than the previous generation?
